Rational® Performance Tester
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.
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.
Encrypted datasets overview
You can encrypt one or more columns in a dataset. If you want to encrypt confidential information such as a set of passwords or account numbers that are used during a test, you can use an encrypted dataset.
Encrypting a dataset column
To secure test data, you must encrypt datasets. You can encrypt data in the columns of a dataset by using an encryption key. When you run a test that utilizes a dataset with encrypted variables, you must enter the encryption key for the encrypted column that the test uses.

    - 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 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.
        Encrypted datasets overview
        You can encrypt one or more columns in a dataset. If you want to encrypt confidential information such as a set of passwords or account numbers that are used during a test, you can use an encrypted dataset.
        Encrypting a dataset column
        To secure test data, you must encrypt datasets. You can encrypt data in the columns of a dataset by using an encryption key. When you run a test that utilizes a dataset with encrypted variables, you must enter the encryption key for the encrypted column that the test uses.
        Decrypting a dataset column
        To view the content of an encrypted dataset, you can decrypt the dataset. Removing encryption from a dataset revokes the protection offered to the test data.
      - 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.

Encrypting a dataset column

To secure test data, you must encrypt datasets. You can encrypt data in the columns of a dataset by using an encryption key. When you run a test that utilizes a dataset with encrypted variables, you must enter the encryption key for the encrypted column that the test uses.

Before you begin

You must have created a dataset. See Creating a dataset in a workspace.

Procedure

Double-click the dataset in the Test Navigator.
The dataset is displayed in a browser.
Right-click any cell in a column that you want to encrypt and select Encrypt column data.
The Encrypt Column window is displayed.
Enter an encryption key in the Encryption Key field to encrypt the data in the column.

Remember: When you have already encrypted other columns in the dataset, you must enter the same encryption key that you used previously. You can use only one encryption key to encrypt columns in a dataset.

Important: The encryption keys you use to encrypt data in a dataset are not stored on the server nor can be retrieved from the server. Therefore, you must remember to store the encryption keys in a secure location. You must use the same encryption keys to view the encrypted values, to decrypt data, or enable the use of the encrypted dataset during test runs.
Click Encrypt Column.
Asterisks are displayed instead of actual data for the encrypted column.

Results

The dataset column is encrypted.
