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.
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.
Adding elements to a Citrix test
You can add a variety of elements to a test, such as user input actions, comments, loops or conditions.
Adding values to an image synchronization
You can replace or add alternative values in an image synchronization element so that synchronization is not restricted to the exact recorded image. Alternative values can also be useful in updating the test if the behavior of the application changes.

  - 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.

      - Citrix test editor overview
        With the test editor, you can inspect or customize a test that you recorded.
      - Citrix synchronization overview
        During the run of a Citrix session, the test uses window events or image recognition to ensure that the correct user input actions are maintained on track with the application events coming from the Citrix server.
      - Verifying application behavior
        To check the expected behavior of the application during a Citrix performance test, you can add verification points at strategic points in the test. You can use window verification points to check that a specific window opens during the test, regardless of its contents, or you can use image synchronization to verify the displayed contents. During the run, verification points produce a pass, fail, error, or inconclusive status in the Citrix Verification Point report. You can also measure response times between two test elements.
      - Adding elements to a Citrix test
        You can add a variety of elements to a test, such as user input actions, comments, loops or conditions.
        Editing a mouse action
        You can edit mouse actions to manually specify how the mouse interacts with the Citrix server.
        Viewing a mouse sequence
        You can use mouse sequences to view complex mouse movements on the screen.
        Editing a keyboard action
        You can edit keyboard actions to manually specify how the keyboard interacts with the Citrix server.
        Editing a text input
        You can edit text inputs to replace a sequence of keyboard events with text strings that are easier to handle as dataset variables or references.
        Synchronizing tests with screen areas
        Image synchronization enables Citrix performance tests to keep track of the contents of a screen area during replay instead of focusing only on window events.
        Manually adding an image synchronization
        You can manually add an image synchronization element to an existing test to ensure that the test synchronizes correctly or to add a verification point. To do this, you must create the image synchronization element, and then perform a single run of the test to retrieve the image hash code or text detected by optical character recognition (OCR).
        Adding values to an image synchronization
        You can replace or add alternative values in an image synchronization element so that synchronization is not restricted to the exact recorded image. Alternative values can also be useful in updating the test if the behavior of the application changes.
        Using custom code with a Citrix test
        You can write custom Java™ code to expand the functions of IBM® Rational® Performance Tester.
    - 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.
    - 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 values to an image synchronization

You can replace or add alternative values in an image synchronization element so that synchronization is not restricted to the exact recorded image. Alternative values can also be useful in updating the test if the behavior of the application changes.

Before you begin

If you are using optical character recognition, simply click Add in an image synchronization element in the test editor to add an alternative value, and enter a new text string in the Expected text field.

If you are using the bitmap hash code synchronization or optical character recognition, you can use the following method to add an alternative hash code or recognized text value.

Procedure

To add an alternative value to an image synchronization:

After inserting an image synchronization element, run the test from the Run menu.
If possible, arrange for the alternative condition to occur before starting the run. The test should produce an image synchronization timeout when the alternative condition is encountered.
In the Performance Test Runs view, right-click the test log container, and then select Display Test Log.
The test log opens in the editor with the Overview page selected.
Click the Events tab.
Expand the top line of the Events hierarchy and navigate to the Image timeout element that was produced during the run.
Select the image timeout to open the Citrix Image Synchronization view.
If necessary, you can open the Citrix Image Synchronization view manually by selecting Window > Show View > Other > Test > Citrix Image Synchronization. When an image timeout is selected, this view shows the actual screen area encountered during the test and the expected image, as well as the corresponding hash codes or recognized text values.
You can either add the new hash code or recognized text value to the image synchronization as an alternative value or you can replace the existing value with the new value.
- To add the actual hash code or recognized text as an alternative value, click the Add value button.
- To replace the expected value with the new value, click the Replace value button.
