# ShouldMatchers

#### trait ShouldMatchers extends Matchers with ShouldVerb

Trait that provides a domain specific language (DSL) for expressing assertions in tests using the word `should`. (If you prefer the word `must`, you can alternatively mix in trait `MustMatchers`.) For example, if you mix `ShouldMatchers` into a suite class, you can write an equality assertion in that suite like this:

    result should equal (3)

Here `result` is a variable, and can be of any type. If the object is an `Int` with the value 3, execution will continue (i.e., the expression will result in the unit value, `()`). Otherwise, a `TestFailedException` will be thrown with a detail message that explains the problem, such as `"7 did not equal 3"`. This `TestFailedException` will cause the test to fail.

The `left should equal (right)` syntax works by calling `==` on the `left` value, passing in the `right` value, on every type except arrays. If both `left` and right are arrays, `deep` will be invoked on both `left` and `right` before comparing them with ==. Thus, even though this expression will yield false, because `Array`'s `equals` method compares object identity:

    Array(1, 2) == Array(1, 2) // yields false

The following expression will not result in a `TestFailedException`, because ScalaTest compares the two arrays structurally, taking into consideration the equality of the array's contents:

    Array(1, 2) should equal (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)

If you ever do want to verify that two arrays are actually the same object (have the same identity), you can use the `be theSameInstanceAs` syntax, described below.

#### Checking size and length

You can check the size or length of just about any type of object for which it would make sense. Here's how checking for length looks:

    result should have length (3)

Size is similar:

    result should have size (10)

The `length` syntax can be used with any object that has a field or method named `length` or a method named `getLength`. Similarly, the `size` syntax can be used with any object that has a field or method named `size` or a method named `getSize`. The type of a `length` or `size` field, or return type of a method, must be either `Int` or `Long`. Any such method must take no parameters. (The Scala compiler will ensure at compile time that the object on which `should` is being invoked has the appropriate structure.)

#### Checking strings

You can check for whether a string starts with, ends with, or includes a substring like this:

    string should startWith ("Hello")
    string should endWith ("world")
    string should include ("seven")

You can check for whether a string starts with, ends with, or includes a regular expression, like this:

    string should startWith regex ("Hel*o")
    string should endWith regex ("wo.ld")
    string should include regex ("wo.ld")

And you can check whether a string fully matches a regular expression, like this:

    string should fullyMatch regex ("""(-)?(\d+)(\.\d*)?""")

The regular expression passed following the `regex` token can be either a `String` or a `scala.util.matching.Regex`.

#### Greater and less than

You can check whether any type that is, or can be implicitly converted to, an `Ordered[T]` is greater than, less than, greater than or equal, or less than or equal to a value of type `T`. The syntax is:

    one should be < (7)
    one should be > (0)
    one should be <= (7)
    one should be >= (0)

#### Checking equality with `be` `=``=``=`

An alternate way to check for equality of two objects is to use `be` with `===`. Here's an example:

    result should be === (3)

Here `result` is a variable, and can be of any type. If the object is an `Int` with the value 3, execution will continue (i.e., the expression will result in the unit value, `()`). Otherwise, a `TestFailedException` will be thrown with a detail message that explains the problem, such as `"7 was not equal to 3"`. This `TestFailedException` will cause the test to fail.

The `left should be === (right)` syntax works by calling `==` on the `left` value, passing in the `right` value, on every type except arrays. If both `left` and right are arrays, `deep` will be invoked on both `left` and `right` before comparing them with ==. Thus, even though this expression will yield false, because `Array`'s `equals` method compares object identity:

    Array(1, 2) == Array(1, 2) // yields false

The following expression will not result in a `TestFailedException`, because ScalaTest compares the two arrays structurally, taking into consideration the equality of the array's contents:

    Array(1, 2) should be === (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)

If you ever do want to verify that two arrays are actually the same object (have the same identity), you can use the `be theSameInstanceAs` syntax, described below.

#### Checking `Boolean` properties with `be`

If an object has a method that takes no parameters and returns boolean, you can check it by placing a `Symbol` (after `be`) that specifies the name of the method (excluding an optional prefix of "`is`"). A symbol literal in Scala begins with a tick mark and ends at the first non-identifier character. Thus, `'empty` results in a `Symbol` object at runtime, as does `'defined` and `'file`. Here's an example:

    emptySet should be ('empty)

Given this code, ScalaTest will use reflection to look on the object referenced from `emptySet` for a method that takes no parameters and results in `Boolean`, with either the name `empty` or `isEmpty`. If found, it will invoke that method. If the method returns `true`, execution will continue. But if it returns `false`, a `TestFailedException` will be thrown that will contain a detail message, such as:

    Set(1, 2, 3) was not empty

This `be` syntax can be used with any type. If the object does not have an appropriately named predicate method, you'll get a `TestFailedException` at runtime with a detail message that explains the problem. (For the details on how a field or method is selected during this process, see the documentation for `BeWord`.)

If you think it reads better, you can optionally put `a` or `an` after `be`. For example, `java.io.File` has two predicate methods, `isFile` and `isDirectory`. Thus with a `File` object named `temp`, you could write:

    temp should be a ('file)

Or, given `java.awt.event.KeyEvent` has a method `isActionKey` that takes no arguments and returns `Boolean`, you could assert that a `KeyEvent` is an action key with:

    keyEvent should be an ('actionKey)

If you prefer to check `Boolean` properties in a type-safe manner, you can use a `BePropertyMatcher`. This would allow you to write expressions such as:

    emptySet should be (empty)
    temp should be a (file)
    keyEvent should be an (actionKey)

These expressions would fail to compile if `should` is used on an inappropriate type, as determined by the type parameter of the `BePropertyMatcher` being used. (For example, `file` in this example would likely be of type `BePropertyMatcher[java.io.File]`. If used with an appropriate type, such an expression will compile and at run time the `Boolean` property method or field will be accessed directly; i.e., no reflection will be used. See the documentation for `BePropertyMatcher` for more information.

#### Using custom `BeMatchers`

If you want to create a new way of using `be`, which doesn't map to an actual property on the type you care about, you can create a `BeMatcher`. You could use this, for example, to create `BeMatcher[Int]` called `odd`, which would match any odd `Int`, and `even`, which would match any even `Int`. Given this pair of `BeMatcher`s, you could check whether an `Int` was odd or even with expressions like:

    num should be (odd)
    num should not be (even)

For more information, see the documentation for `BeMatcher`.

#### Checking object identity

If you need to check that two references refer to the exact same object, you can write:

    ref1 should be theSameInstanceAs (ref2)

#### Checking numbers against a range

To check whether a floating point number has a value that exactly matches another, you can use `should equal`:

    sevenDotOh should equal (7.0)

Often, however, you may want to check whether a floating point number is within a range. You can do that using `be` and `plusOrMinus`, like this:

    sevenDotOh should be (6.9 plusOrMinus 0.2)

This expression will cause a `TestFailedException` to be thrown if the floating point value, `sevenDotOh` is outside the range `6.7` to `7.1`. You can also use `plusOrMinus` with integral types, for example:

    seven should be (6 plusOrMinus 2)

#### Traversables, iterables, sets, sequences, and maps

You can use some of the syntax shown previously with `Iterable` and its subtypes. For example, you can check whether an `Iterable` is `empty`, like this:

    iterable should be ('empty)

You can check the length of an `Seq` (`Array`, `List`, etc.), like this:

    array should have length (3)
    list should have length (9)

You can check the size of any `Traversable`, like this:

    map should have size (20)
    set should have size (90)

In addition, you can check whether an `Iterable` contains a particular element, like this:

    iterable should contain ("five")

You can also check whether a `Map` contains a particular key, or value, like this:

    map should contain key (1)
    map should contain value ("Howdy")

#### Java collections and maps

You can use similar syntax on Java collections (`java.util.Collection`) and maps (`java.util.Map`). For example, you can check whether a Java `Collection` or `Map` is `empty`, like this:

    javaCollection should be ('empty)
    javaMap should be ('empty)

Even though Java's `List` type doesn't actually have a `length` or `getLength` method, you can nevertheless check the length of a Java `List` (`java.util.List`) like this:

    javaList should have length (9)

You can check the size of any Java `Collection` or `Map`, like this:

    javaMap should have size (20)
    javaSet should have size (90)

In addition, you can check whether a Java `Collection` contains a particular element, like this:

    javaCollection should contain ("five")

One difference to note between the syntax supported on Java collections and that of Scala iterables is that you can't use `contain (...)` syntax with a Java `Map`. Java differs from Scala in that its `Map` is not a subtype of its `Collection` type. If you want to check that a Java `Map` contains a specific key/value pair, the best approach is to invoke `entrySet` on the Java `Map` and check that entry set for the appropriate element (a `java.util.Map.Entry`) using `contain (...)`.

Despite this difference, the other (more commonly used) map matcher syntax works just fine on Java `Map`s. You can, for example, check whether a Java `Map` contains a particular key, or value, like this:

    javaMap should contain key (1)
    javaMap should contain value ("Howdy")

#### Be as an equality comparison

All uses of `be` other than those shown previously perform an equality comparison. In other words, they work the same as `equals`. This redundance between `be` and `equals` exists because it enables syntax that sometimes sounds more natural. For example, instead of writing:

    result should equal (null)

You can write:

    result should be (null)

(Hopefully you won't write that too much given `null` is error prone, and `Option` is usually a better, well, option.) Here are some other examples of `be` used for equality comparison:

    sum should be (7.0)
    boring should be (false)
    fun should be (true)
    list should be (Nil)
    option should be (None)
    option should be (Some(1))

As with `equal`, using `be` on two arrays results in `deep` being called on both arrays prior to calling `equal`. As a result, the following expression would not throw a `TestFailedException`:

    Array(1, 2) should be (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)

Because `be` is used in several ways in ScalaTest matcher syntax, just as it is used in many ways in English, one potential point of confusion in the event of a failure is determining whether `be` was being used as an equality comparison or in some other way, such as a property assertion. To make it more obvious when `be` is being used for equality, the failure messages generated for those equality checks will include the word `equal` in them. For example, if this expression fails with a `TestFailedException`:

    option should be (Some(1))

The detail message in that `TestFailedException` will include the words `"equal to"` to signify `be` was in this case being used for equality comparison:

    Some(2) was not equal to Some(1)

#### Being negative

If you wish to check the opposite of some condition, you can simply insert `not` in the expression. Here are a few examples:

    result should not be (null)
    sum should not be <= (10)
    mylist should not equal (yourList)
    string should not startWith ("Hello")

#### Logical expressions with `and` and `or`

You can also combine matcher expressions with `and` and/or `or`, however, you must place parentheses or curly braces around the `and` or `or` expression. For example, this `and`-expression would not compile, because the parentheses are missing:

    map should contain key ("two") and not contain value (7) // ERROR, parentheses missing!

Instead, you need to write:

    map should (contain key ("two") and not contain value (7))

Here are some more examples:

    number should (be > (0) and be <= (10))
    option should (equal (Some(List(1, 2, 3))) or be (None))
    string should (
      equal ("fee") or
      equal ("fie") or
      equal ("foe") or
      equal ("fum")
    )

Two differences exist between expressions composed of these `and` and `or` operators and the expressions you can write on regular `Boolean`s using its `&&` and `||` operators. First, expressions with `and` and `or` do not short-circuit. The following contrived expression, for example, would print `"hello, world!"`:

    "yellow" should (equal ("blue") and equal { println("hello, world!"); "green" })

In other words, the entire `and` or `or` expression is always evaluated, so you'll see any side effects of the right-hand side even if evaluating only the left-hand side is enough to determine the ultimate result of the larger expression. Failure messages produced by these expressions will "short-circuit," however, mentioning only the left-hand side if that's enough to determine the result of the entire expression. This "short-circuiting" behavior of failure messages is intended to make it easier and quicker for you to ascertain which part of the expression caused the failure. The failure message for the previous expression, for example, would be:

    "yellow" did not equal "blue"

Most likely this lack of short-circuiting would rarely be noticeable, because evaluating the right hand side will usually not involve a side effect. One situation where it might show up, however, is if you attempt to `and` a `null` check on a variable with an expression that uses the variable, like this:

    map should (not be (null) and contain key ("ouch"))

If `map` is `null`, the test will indeed fail, but with a `NullPointerException`, not a `TestFailedException`. Here, the `NullPointerException` is the visible right-hand side effect. To get a `TestFailedException`, you would need to check each assertion separately:

    map should not be (null)
    map should contain key ("ouch")

If `map` is `null` in this case, the `null` check in the first expression will fail with a `TestFailedException`, and the second expression will never be executed.

The other difference with `Boolean` operators is that although `&&` has a higher precedence than `||`, `and` and `or` have the same precedence. Thus although the `Boolean` expression `(a || b && c)` will evaluate the `&&` expression before the `||` expression, like `(a || (b && c))`, the following expression:

    traversable should (contain (7) or contain (8) and have size (9))

Will evaluate left to right, as:

    traversable should ((contain (7) or contain (8)) and have size (9))

If you really want the `and` part to be evaluated first, you'll need to put in parentheses, like this:

    traversable should (contain (7) or (contain (8) and have size (9)))

#### Working with `Option`s

ScalaTest matchers has no special support for `Option`s, but you can work with them quite easily using syntax shown previously. For example, if you wish to check whether an option is `None`, you can write any of:

    option should equal (None)
    option should be (None)
    option should not be ('defined)
    option should be ('empty)

If you wish to check an option is defined, and holds a specific value, you can write either of:

    option should equal (Some("hi"))
    option should be (Some("hi"))

If you only wish to check that an option is defined, but don't care what it's value is, you can write:

    option should be ('defined)

#### Checking arbitrary properties with `have`

Using `have`, you can check properties of any type, where a property is an attribute of any object that can be retrieved either by a public field, method, or JavaBean-style `get` or `is` method, like this:

    book should have (
      'title ("Programming in Scala"),
      'author (List("Odersky", "Spoon", "Venners")),
      'pubYear (2008)
    )

This expression will use reflection to ensure the `title`, `author`, and `pubYear` properties of object `book` are equal to the specified values. For example, it will ensure that `book` has either a public Java field or method named `title`, or a public method named `getTitle`, that when invoked (or accessed in the field case) results in a the string `"Programming in Scala"`. If all specified properties exist and have their expected values, respectively, execution will continue. If one or more of the properties either does not exist, or exists but results in an unexpected value, a `TestFailedException` will be thrown that explains the problem. (For the details on how a field or method is selected during this process, see the documentation for `HavePropertyMatcherGenerator`.)

When you use this syntax, you must place one or more property values in parentheses after `have`, seperated by commas, where a property value is a symbol indicating the name of the property followed by the expected value in parentheses. The only exceptions to this rule is the syntax for checking size and length shown previously, which does not require parentheses. If you forget and put parentheses in, however, everything will still work as you'd expect. Thus instead of writing:

    array should have length (3)
    set should have size (90)

You can alternatively, write:

    array should have (length (3))
    set should have (size (90))

If a property has a value different from the specified expected value, a `TestFailedError` will be thrown with a detail message that explains the problem. For example, if you assert the following on a `book` whose title is `Moby Dick`:

    book should have ('title ("A Tale of Two Cities"))

You'll get a `TestFailedException` with this detail message:

    The title property had value "Moby Dick", instead of its expected value "A Tale of Two Cities",
    on object Book("Moby Dick", "Melville", 1851)

If you prefer to check properties in a type-safe manner, you can use a `HavePropertyMatcher`. This would allow you to write expressions such as:

    book should have (
      title ("Programming in Scala"),
      author (List("Odersky", "Spoon", "Venners")),
      pubYear (2008)
    )

These expressions would fail to compile if `should` is used on an inappropriate type, as determined by the type parameter of the `HavePropertyMatcher` being used. (For example, `title` in this example might be of type `HavePropertyMatcher[org.publiclibrary.Book]`. If used with an appropriate type, such an expression will compile and at run time the property method or field will be accessed directly; i.e., no reflection will be used. See the documentation for `HavePropertyMatcher` for more information.

#### Using custom matchers

If none of the built-in matcher syntax (or options shown so far for extending the syntax) satisfy a particular need you have, you can create custom `Matcher`s that allow you to place your own syntax directly after `should`. For example, class `java.io.File` has a method `exists`, which indicates whether a file of a certain path and name exists. Because the `exists` method takes no parameters and returns `Boolean`, you can call it using `be` with a symbol or `BePropertyMatcher`, yielding assertions like:

    file should be ('exists)  // using a symbol
    file should be (inExistance)   // using a BePropertyMatcher

Although these expressions will achieve your goal of throwing a `TestFailedException` if the file does not exist, they don't produce the most readable code because the English is either incorrect or awkward. In this case, you might want to create a custom `Matcher[java.io.File]` named `exist`, which you could then use to write expressions like:

    // using a plain-old Matcher
    file should exist
    file should not (exist)
    file should (exist and have ('name ("temp.txt")))

Note that when you use custom `Matcher`s, you will need to put parentheses around the custom matcher in more cases than with the built-in syntax. For example you will often need the parentheses after `not`, as shown above. (There's no penalty for always surrounding custom matchers with parentheses, and if you ever leave them off when they are needed, you'll get a compiler error.) For more information about how to create custom `Matcher`s, please see the documentation for the `Matcher` trait.

#### Checking for expected exceptions

Sometimes you need to test whether a method throws an expected exception under certain circumstances, such as when invalid arguments are passed to the method. With `ShouldMatchers` mixed in, you can check for an expected exception like this:

    evaluating { s.charAt(-1) } should produce [IndexOutOfBoundsException]

If `charAt` throws an instance of `StringIndexOutOfBoundsException`, this expression will result in that exception. But if `charAt` completes normally, or throws a different exception, this expression will complete abruptly with a `TestFailedException`. This expression returns the caught exception so that you can inspect it further if you wish, for example, to ensure that data contained inside the exception has the expected values. Here's an example:

    val thrown = evaluating { s.charAt(-1) } should produce [IndexOutOfBoundsException]
    thrown.getMessage should equal ("String index out of range: -1")

#### Those pesky parens

Perhaps the most tricky part of writing assertions using ScalaTest matchers is remembering when you need or don't need parentheses, but bearing in mind a few simple rules should help. It is also reassuring to know that if you ever leave off a set of parentheses when they are required, your code will not compile. Thus the compiler will help you remember when you need the parens. That said, the rules are:

1. Although you don't always need them, it is recommended style to always put parentheses around right-hand values, such as the `7` in `num should equal (7)`:

    result should equal (4)
    array should have length (3)
    book should have (
      'title ("Programming in Scala"),
      'author (List("Odersky", "Spoon", "Venners")),
      'pubYear (2008)
    )
    option should be ('defined)
    catMap should (contain key (9) and contain value ("lives"))
    keyEvent should be an ('actionKey)
    javaSet should have size (90)

2. Except for `length` and `size`, you must always put parentheses around the list of one or more property values following a `have`:

    file should (exist and have ('name ("temp.txt")))
    book should have (
      title ("Programming in Scala"),
      author (List("Odersky", "Spoon", "Venners")),
      pubYear (2008)
    )
    javaList should have length (9) // parens optional for length and size

3. You must always put parentheses around `and` and `or` expressions, as in:

    catMap should (contain key (9) and contain value ("lives"))
    number should (equal (2) or equal (4) or equal (8))

4. Although you don't always need them, it is recommended style to always put parentheses around custom `Matcher`s when they appear directly after `not`:

    file should exist
    file should not (exist)
    file should (exist and have ('name ("temp.txt")))
    file should (not (exist) and have ('name ("temp.txt"))
    file should (have ('name ("temp.txt") or exist)
    file should (have ('name ("temp.txt") or not (exist))

That's it. With a bit of practice it should become natural to you, and the compiler will always be there to tell you if you forget a set of needed parentheses.

    Implicit conversion from `Any` to `Equalizer`, used to enable assertions with `===` comparisons.

    Implicit conversion from `Any` to `Equalizer`, used to enable assertions with `===` comparisons.

    For more information on this mechanism, see the documentation for Equalizer.

    Because trait `Suite` mixes in `Assertions`, this implicit conversion will always be available by default in ScalaTest `Suite`s. This is the only implicit conversion that is in scope by default in every ScalaTest `Suite`. Other implicit conversions offered by ScalaTest, such as those that support the matchers DSL or `invokePrivate`, must be explicitly invited into your test code, either by mixing in a trait or importing the members of its companion object. The reason ScalaTest requires you to invite in implicit conversions (with the exception of the implicit conversion for `===` operator) is because if one of ScalaTest's implicit conversions clashes with an implicit conversion used in the code you are trying to test, your program won't compile. Thus there is a chance that if you are ever trying to use a library or test some code that also offers an implicit conversion involving a `===` operator, you could run into the problem of a compiler error due to an ambiguous implicit conversion. If that happens, you can turn off the implicit conversion offered by this `convertToEqualizer` method simply by overriding the method in your `Suite` subclass, but not marking it as implicit:

        // In your Suite subclass
        override def convertToEqualizer(left: Any) = new Equalizer(left)

    This method enables the following syntax:

                      ^

    The `left should equal (right)` syntax works by calling `==` on the `left` value, passing in the `right` value, on every type except arrays. If both `left` and right are arrays, `deep` will be invoked on both `left` and `right` before comparing them with ==. Thus, even though this expression will yield false, because `Array`'s `equals` method compares object identity:

        Array(1, 2) == Array(1, 2) // yields false

    The following expression will not result in a `TestFailedException`, because ScalaTest will compare the two arrays structurally, taking into consideration the equality of the array's contents:

        Array(1, 2) should equal (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)

    If you ever do want to verify that two arrays are actually the same object (have the same identity), you can use the `be theSameInstanceAs` syntax.

     Intercept and return an exception that's expected to be thrown by the passed function value. The thrown exception must be an instance of the type specified by the type parameter of this method. This method invokes the passed function. If the function throws an exception that's an instance of the specified type, this method returns that exception. Else, whether the passed function returns normally or completes abruptly with a different exception, this method throws `TestFailedException`.

     Note that the type specified as this method's type parameter may represent any subtype of `AnyRef`, not just `Throwable` or one of its subclasses. In Scala, exceptions can be caught based on traits they implement, so it may at times make sense to specify a trait that the intercepted exception's class must mix in. If a class instance is passed for a type that could not possibly be used to catch an exception (such as `String`, for example), this method will complete abruptly with a `TestFailedException`.

     f

       the function value that should throw the expected exception

     manifest

       an implicit `Manifest` representing the type of the specified type parameter.

     returns

       the intercepted exception, if it is of the expected type

119. #### def withClue (clue: Any)(fun: ⇒ Unit): Unit

     Executes the block of code passed as the second parameter, and, if it completes abruptly with a `ModifiableMessage` exception, prepends the "clue" string passed as the first parameter to the beginning of the detail message of that thrown exception, then rethrows it.

     Executes the block of code passed as the second parameter, and, if it completes abruptly with a `ModifiableMessage` exception, prepends the "clue" string passed as the first parameter to the beginning of the detail message of that thrown exception, then rethrows it. If clue does not end in a white space character, one space will be added between it and the existing detail message (unless the detail message is not defined).

     This method allows you to add more information about what went wrong that will be reported when a test fails. Here's an example:

         withClue("(Employee's name was: " + employee.name + ")") {
           intercept[IllegalArgumentException] {
             employee.getTask(-1)
           }
         }

     If an invocation of `intercept` completed abruptly with an exception, the resulting message would be something like:

         (Employee's name was Bob Jones) Expected IllegalArgumentException to be thrown, but no exception was thrown
