  This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing. This guide is intended for Integration testers.
- Tester Guide - Performance Testing
  Typically, a user with the Integration Tester role is also responsible for performance testing. This guide lists all such topics.
  - Creating and running performance tests
    This topic describes how to create, configure, and run performance tests.
    - Before creating performance tests
      Agents (Rational® Integration Tester Agent) are required on the computers that will run IBM® Rational Integration Tester tests and the probes that monitor the systems.
    - Creating performance tests
      A performance test is created within a Rational® Integration Tester project.
      - Execution
        Select the root of the performance test in the configuration tree to display its configuration details, as shown below.
      - Configuring references
        You can configure a performance test to run scenarios, which are collections of stubs, that are available on the IBM® Rational® Test Control Panel domain associated with your Rational Integration Tester project.
      - Configuring probes
        The Probes tab (on the Config tab) is used to configure which probes to run during the test, and where to run them.
      - Adding distributed tests
        You can add distributed tests to a performance test.
        Configuring execution options
        On the Execution tab, you can modify the name of the selected test as well as the Rational® Integration Tester test that it should run.
        Load-generating tests
        If the load profile for the selected test is Constant Growth, the execution parameters will be defined in this topic and the number of test phases and their duration are fixed.
        Background tests
        A background test simply runs the selected test repeatedly while the performance test is active.
        Test engines
        Test engines are instances of Rational® Integration Tester that execute performance tests.
        Configuring input mappings
        On the Input Mappings tab, you can map values from a selected test data set to the tags in your test.
        Descriptions/notes
        On the Documentation tab, you can enter a description or notes about the selected test, and specify the test’s owner.
        Timed sections
        When tests are run within a distributed test in IBM® Rational® Performance Test Server, the overall execution times (that is, start to finish) are recorded.
      - Log Measurement action (optional)
        With the Log Measurement action, you can periodically record custom data, that is, data that is not provided by test engines and probes, as a performance test runs. The recorded data is stored in a database and is used to generate performance charts. Each item of data that is recorded is called a counter. Attributes are used to identify the counters. A UTC time stamp is stored with each set of counters.
    - Performance tests
      Performance tests are executed in Rational® Integration Tester in the same way and from the same perspectives as any other test resource.
    - Troubleshooting: Running a performance test with a MySQL database
      You can troubleshoot an issue that you encounter while you run a performance test with a MySQL database.
  - View test results
    This topic describes how to work with IBM® Rational® Performance Test Server charts in the Results Gallery perspective.
  - Deploying probes
    A Rational® Integration Tester probe measures variables from a particular component in the system and reports back its findings for processing and storage.
- Tester Guide - Service Virtualization
  This guide describes the tasks that you can perform for using virtual services or stubs to simulate parts of an environment if the real services are not yet available or because they are difficult or expensive to use. This guide is intended for Integration Testers.

Adding distributed tests

You can add distributed tests to a performance test.

About this task

The following types of distributed tests can be added to a performance test:

A load-generating test, which can have a fixed or varied load profile, such as a linear increase in published messages.
A background test, which may be used to create a custom probe by allowing statistics to be gathered (for example, by a subscriber) and recorded using a Log Measurement action. Background tests are not used to collect timing information (any timed sections are ignored). For more information, see Background tests.

Both test types run an existing Rational® Integration Tester test and data may be mapped using an existing test data set. One or more tests can be added to the root of the performance test.

Note: If a performance test has more than one distributed test, they are executed concurrently.

To add a distributed test to the performance test:

Procedure

Right-click the root of the test and click the required distributed test to add.
Note: Rational® Integration Tester enables you to add test actions that provide timing information for specific parts of the tests. For information about this, refer to Timed sections.
After a distributed test has been added to the performance test, it must be configured. Select the required test from the performance test tree and use the following tabs to modify its properties
