Test Author Guide
This guide describes how to create test scripts in Rational® Performance Tester and enhances tests by applying different test elements such as dataset, variables, and verification points. This guide is intended for testers.
Editing tests
After you record a test, you can edit it to include datasets (to provide variable data rather than the data that you recorded), verification points (to confirm that the test runs as expected), and data correlation (to ensure that returned data is appropriate for the corresponding request). You can also add protocol-specific elements to a test. When you edit a test, the modified items appear in italic type. The italic type changes to regular type after you save the test.
Adding test elements
You can add a variety of elements to a test, such as transaction blocks, IF-THEN conditions, loops, and comments.
Adding data source controller
Use this test element to control how the data is fetched from the data sources to be used by the test. You can use data from dataset, array variables, built-in data sources, and correlation.

This guide describes how to create test scripts in Rational® Performance Tester and enhances tests by applying different test elements such as dataset, variables, and verification points. This guide is intended for testers.
- Creating tests
  To create a test, you record representative interactions with an application.
- Editing tests
  After you record a test, you can edit it to include datasets (to provide variable data rather than the data that you recorded), verification points (to confirm that the test runs as expected), and data correlation (to ensure that returned data is appropriate for the corresponding request). You can also add protocol-specific elements to a test. When you edit a test, the modified items appear in italic type. The italic type changes to regular type after you save the test.
  - Editing HTTP tests
    After you record a test, you can edit it to include variable data rather than the data that you recorded and can include verification points to confirm that the test runs as expected. You can also edit the test to include [NB1] transactions, conditional processing, custom code, and standard header or custom header to a request or response.
  - Editing SAP tests
    After you record a test, you can edit it to include variable data (rather than the data that you recorded) and verification points (to confirm that the test runs as expected).
  - Editing Citrix tests
    After you record a test, you can edit it to include variable data (rather than the data that you recorded), verification points (to confirm that the test runs as expected), transactions, conditional processing, and custom code.
  - Editing service tests
    After you record a service test, you can edit the calls and message returns to include variable data (rather than the data that you recorded). You can add verification points (to confirm that the test runs as expected), transactions, conditional processing, and custom code.
  - Editing Socket tests
    Improve the Socket tests by adding test elements.
  - Editing Kerberos tests
    You can change the Kerberos realm, user name, and password when editing tests.
  - Adding test elements
    You can add a variety of elements to a test, such as transaction blocks, IF-THEN conditions, loops, and comments.
    - Adding a comment
      You can add a comment to document a test.
    - Adding a transaction to a test
      A transaction is a specific group of test elements whose performance you are interested in. When viewing the test results, you can view performance data about any transactions that you have added.
    - Adding conditional logic
      You can add IF-THEN conditional logic around portions of a test/compound test or a schedule, in this context, is used to refer to both VU Schedule and Rate Schedule to make those portions run if a specific condition is met.
    - Synchronizing users in tests
      By inserting a synchronization point, you can coordinate the activities of a number of virtual users by pausing and resuming activities. You can synchronize all virtual users at the beginning of a test and stagger the release times so that the users do not overload the system. Synchronization points are also useful in stress testing.
    - Adding a loop to a test
      You can define part of a test as a loop that runs a specified number of times. If the loop contains a synchronization point, the synchronization point is released after the first iteration of the loop and stays released for all further iterations.
    - Adding Dataset Mapper
      You can include a Dataset Mapper in a compound test or a schedule to assign the dataset values to the variables that are defined in multiple tests. In previous releases, to apply the dataset values to multiple tests, you had to associate the dataset to each test. The Dataset Mapper is able to map the dataset columns with the variables.
    - Adding data source controller
      Use this test element to control how the data is fetched from the data sources to be used by the test. You can use data from dataset, array variables, built-in data sources, and correlation.
    - Controlling the flow of test
      A test is usually run in the order it was recorded. However, you might want to add some conditions to the test that the users would actually face when interacting with the application under test. For example, if you select a product, you want to know its manufacturing date. If the date is not available, you want to exit. You can now add such control to the test.
  - Searching within tests
    Search request data or response content by right-clicking in the data or content and selecting Find. To search for specific element types and to display the results in a table, click Select. For a still more powerful search and replace, use the Test Search function.
  - Exporting a test
    To share the test scripts with manual testers or reviewers who do not have the workbench, export the test scripts to text files. You can export one file at a time.
  - Copying test assets with dependencies
    You can export test assets, and then import them into another project or workspace without losing any dependencies. Test assets include projects, schedules, and tests. You can export and import test assets to collaborate with other testers.
  - Disabling portions of a test
    When you disable portions of a test, you can still see the disabled portion, but it is not executed during a run. You can also disable portions of a schedule by using the following procedure.
  - Running test elements in random order
    You can record multiple user scenarios in a test and then run each scenario in a random order. To do this, you put each scenario under a random selector and then select the proportion of time that the scenario should be run.
  - Renaming test assets
    As your test assets increase and become more complex, you might want to rename them. Use the Eclipse Rename function or save the assets under a different name.
  - Deleting test assets
    As your test assets grow and become more complicated, you might want to delete the assets that you no longer use.
  - Debugging custom code for tests and compound tests
    If you have custom code added to a test or a compound test, you can debug the custom code for any errors by clicking the Debug button.
  - Providing tests with variable data (datasets)
    You can produce more realistic tests by changing them to use datasets. During execution, a test that uses a dataset replaces a value in the recorded test with variable test data that is stored in the dataset. This substitution allows each virtual user to generate a different request to the server.
  - Test variables
    A test variable is a user-defined, name-value pair that stores and refers to information throughout a test and between tests.
  - Correlating response and request data
    For a test to run correctly, a request that is sent to a server might need to use a value that was returned by a previous request. By ensuring that this data is correlated accurately, you can produce better performance tests.
  - Data transformation
    You can transform HTTP application specific data such as JSON data, binary data and encoded data to a more readable format to use data correlation.
- Compound tests
  You can create compound tests to help you organize smaller tests into scenarios that can then be run end-to-end. You can combine tests from different extensions to achieve end-to-end flow.
- Simulating services with stubs
  Service stubs enable you to simulate the behavior of an actual service for a wide variety testing or integration purposes.
- Sending service requests with the generic service client
  The generic service client enables you to send requests to services for which you do not have a convenient client and to view the responses returned by the service.
- Emulating workloads
  You emulate a workload by creating a schedule and adding user groups/rate runner groups, tests, and other elements to it.

Adding data source controller

Use this test element to control how the data is fetched from the data sources to be used by the test. You can use data from dataset, array variables, built-in data sources, and correlation.

About this task

In the Test editor, the pages/requests succeeding the data source controller makes use of the data source associated to the controller. So, if there are 3 pages in your test and the first controller is placed before the first page and the second controller is before the last page, the first two pages use data associated with the first controller. The last page will use data associated with the second controller.

Procedure

In the Test editor, select the pages for which you want to substitute data and click Insert > Data Source Controller.
Select the data source from where you want the succeeding pages to pick data and click Select.
The data source controller is added to the test.
In Data Source Controller Details section, select Increment for the test to automatically pick the next value from the data source or select Reset to pick the first available value from the data source.
Optional: To change the data source, click Data Source and save the test.
