Use the Test Data
Sources window to add or change data correlation for any
supported test element.
The test generator attempts to perform automated data correlation.
You can also manually correlate request values with other test data.
The
Test Data Sources window displays the following
types of test data that you can substitute from:
- References
- Datapools
- Custom code
- Test variables
- Built-in variables
You can right-click references, custom code, and built-in variables
to display a menu that contains commonly used commands. In addition,
there is a toolbar and a menu at the top of the
Test Data
Sources window that you can use to perform common operations,
such as creating a datapool or switching from tree view to list view.
The
Substitute From button is enabled when
you select a substitution site in the test editor and a data source
from one of the five categories in the
Test Data Sources window.
Click
Substitute From to correlate the data
source and the substitution site.

- References
- The data sources that have been created in the test and the potential
matches that are available for a selected substitution site. For example,
text that is found in a response and used in a subsequent request
is automatically created as a reference. Clear the Matching
References Only check box to see all the references that
occur before the substitution site in the test. Select Include
Potential Matches to see a list of locations that might
match the substitution site. Replace the text type filter
text with keywords to filter the list of references.
Select a reference in the References table
to display the reference in the pane at the bottom of the window.
Use the buttons to the left of the preview pane to switch between
inline view and tree view.
- Datapools
- The datapools that have been added to the test. To add a new datapool,
click the Add new Datapool icon (
).
- Custom Code
- The custom code that is available as data sources for this substitution
site, if you have written Test Execution Services (TES) custom code.
- Test Variables
- The test variables and their types that are available as data
sources for this substitution site. Replace the text type
filter text with keywords to filter the list of test
variables.
- Built-in Variables
- The dynamically calculated variables, Current Date and Timestamp,
that are available as data sources for this substitution site. To
create a built-in variable, right-click inside the Built-in
Variables page, and select New,
or click the New button at the top of the window.
Detaching the Test Data Sources window
The Test
Data Sources window is detachable. To detach the Test
Data Sources window, right-click the Test Data
Sources tab, and then select Detached.
When detached, the Test Data Sources window is
always displayed in front of the other windows that make up the workbench.
