This section provides a reference list of static metrics displayed in the Create New Component Test wizard for Java™ and EJB component tests. These metrics can help you measure the impact of your test and can help you define a test strategy.
Name | Formula | Description |
---|---|---|
Fan In |
![]() |
Number of public methods + public attributes of the class or EJB |
FanOut |
![]() |
Number of distinct utilizations of methods or attributes defined outside the class or EJB |
ExtUse |
![]() |
Number of distinct classes or EJBs that use public attributes or methods of the measured class or EJB. |
Name | Formula | Description |
---|---|---|
Methods |
![]() |
Methods (or weighted number of methods per class) is a count of the methods in a class or EJB. |
WAC |
![]() |
Attributes (or weighted number of attributes per class) is the number of attributes of a class or EJB. |
Max V(g) |
![]() ![]()
|
The V(g) or cyclomatic number is an indicator of the complexity of a method. This is correlated with the difficulty of testing. Typically, V(g) varies between 1 and 10 where a value of 1 means the code has no branching. A method's cyclomatic complexity should not exceed 10. Max V(g) is the highest V(g) value encountered among all methods of the class or EJB. |
Statements |
![]() |
This metric simply represents the total number of source lines of code (SLOC), excluding comments. |
Max nested levels |
![]() |
The nested level indicates the number of levels contained in the structure. The Max nested level is the highest value encountered among all methods of the class or EJB. This is correlated with the complexity of the structure and, therefore, the difficulty of testing. |
Name | Description |
---|---|
NbTests |
Number of times that the method has been called from a test suite. |
Line (%) |
Line coverage rate (in percent) of the class within all runs. This metric is only available when you have previously run the component test with profiling engaged. |
