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.
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.
Viewing dataset candidates when you open a test
Dataset candidates are displayed automatically when you open a test for the first time. From the dataset candidates window you can view the dataset candidates in the test, bookmark locations of interest, and add or remove dataset references.

- 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.
  - 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.
    - Dataset overview
      Datasets provide tests with variable data during a run. When you record a test, you perform a sequence of steps that you expect a typical user to perform. After the recording, a test is generated that captures these interactions. When you run this test, it uses the same data that you used during recording. To vary the data in the test, you use a dataset, that contains variable data. At run time, this variable data is substituted for the data in the recorded test.
    - Creating a dataset associated with a test
      You can create a dataset that contains variable data for tests to use when they run. This is the preferred way to create a dataset because the dataset is automatically associated with a test. You can create anything from an empty dataset that contains one column, which you can edit later, to a fully functioning dataset.
    - Creating a dataset in a workspace
      You can create datasets in a workspace containing variable data that tests use when they run. You can use this method to create a dataset if you have not yet created the test that will use it.
    - Converting an existing datapool to a dataset
      Starting from 9.5 the dataset formerly known as datapool is in the CSV format. You can convert any existing datapool to a dataset.
    - Creating datasets with multiple substitutions
      Earlier to 9.2, you could substitute one dataset value at a time. Starting from 9.2, after the test is generated, you can view all the dataset candidates, add multiple candidates as dataset values, substitute values, and create a new dataset out of it. You can also substitute multiple dataset candidates for an existing dataset.
    - How dataset options affect values that a virtual user retrieves
      The Open, Access, and Wrap modes that you select for a dataset affect the values that a virtual user retrieves.
    - Enabling a test to use a dataset
      Before a test can use variable data from a dataset, you must update the test to include a reference to that dataset.
    - Associating a test value with a dataset column
      After you have created a dataset and have enabled your test to use the dataset, you can associate a specific value in the test with a specific dataset column.
    - Viewing dataset candidates when you open a test
      Dataset candidates are displayed automatically when you open a test for the first time. From the dataset candidates window you can view the dataset candidates in the test, bookmark locations of interest, and add or remove dataset references.
    - Editing datasets
      You can add, modify, remove, import, or export data from a dataset by using the CSV Editor. The working principle of the CSV Editor is similar to that of a spreadsheet.
    - Using a digital certificate store with a dataset
      You can associate the certificates in one or more certificate stores with a dataset to use multiple digital certificates during testing.
    - Navigating between a dataset and a test
      After you have created a dataset or imported a comma-separate values (CSV) file into a dataset, you can navigate between the dataset and associated tests in the test editor. You can enlarge the test and the dataset, list the datasets that a test uses, navigate from a row in a dataset to the corresponding element in the test, see the data for a page or request, and add or remove dataset references.
  - 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.

Viewing dataset candidates when you open a test

Dataset candidates are displayed automatically when you open a test for the first time. From the dataset candidates window you can view the dataset candidates in the test, bookmark locations of interest, and add or remove dataset references.

Procedure

Record a test.
When the test opens for the first time in the Test Navigator, the Show Dataset Candidates window is displayed. The Show Dataset Candidates window is displayed only if there are dataset candidates and if Always display this dialog when a test is first opened is selected. To prevent the Show Dataset Candidates from being displayed when a test opens, clear the Always display this dialog when a test is first opened check box in the Show Dataset Candidates window.

Do one of the following:

Option	Description
To view details about the dataset candidates in a test	Navigate through the Dataset Candidates field to see them previewed in the Preview pane. Click the Next and Previous icons to move the selection down or up in the list of dataset candidates. Click the Show as Tree icon to toggle between tree format and list format. Click the Sort icon to sort the list of dataset candidates. Click the Bookmark icon to bookmark a location for later review.
To select a data source for a dataset candidate	Select the dataset candidate in the Dataset Candidates field, and then click Substitute. The Select Data Source window opens.
To find more values in the test that have the same value as the selected dataset candidate	Click Find More and Substitute. These values can be reviewed and substituted interactively as needed.
To remove a substitution	Select a substitution site, and then click Remove Substitution.

Click Close to close the Show Dataset Candidates window and proceed to the test in the test editor.
To display the Show Dataset Candidates window again while in the test editor, click the root node of the test. Then click the Common Options tab under Test Element Details, and then click Show Dataset Candidates.
