Test Execution Specialist Guide
This guide describes tasks that you can perform on schedules, test execution with custom code, and Extending Rational® Performance Tester to support other protocols. This guide is intended for testers or test execution specialists.
Extending test execution with custom code
You can extend how you run your tests by writing custom Java™ code and calling the code from the test. You can also specify that results from the tests that are affected by your custom code be included in reports.
Migrating custom code from previous versions
You can run scripts that contain custom code from previous releases and edit tests to make new calls to old or new custom code classes.

Rational® Performance Tester
- Release Notes
  This document contains information about what's new, installation instructions, known issues in IBM® Rational® Performance Tester and contact information of IBM Customer Support.
- System Requirements
  This document includes information about hardware and software requirements for IBM® Rational® Performance Tester.
- Getting Started
  This guide provides an overview and describes the task flows to get you to start with Rational® Performance Tester. This guide is intended for new users.
- Tutorials
  This section contains the tutorials which explains the main features of Rational® Performance Tester.
- Samples
  This section describes about the sample project which can be used with Rational® Performance Tester to test the functionality of an application.
- Administrator Guide
  This guide describes how to install Rational® Performance Tester. After you install the product, you can perform administration tasks such as license configuration and integration with other products. This guide is intended for administrators.
- 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.
- Test Execution Specialist Guide
  This guide describes tasks that you can perform on schedules, test execution with custom code, and Extending Rational® Performance Tester to support other protocols. This guide is intended for testers or test execution specialists.
  - Running schedules with performance testing
    After you have added the user groups, tests, and other items to a schedule, and you are satisfied that it represents a realistic workload, you run the schedule.
  - Extending test execution with custom code
    You can extend how you run your tests by writing custom Java™ code and calling the code from the test. You can also specify that results from the tests that are affected by your custom code be included in reports.
    - Creating custom Java™ code
      Custom code uses references in the test as input and returns modified values to the test. Use the ICustomCode2 interface to create custom code and the ITestExecutionServices interface to extend test execution. These interfaces are contained in the com.ibm.rational.test.lt.kernel.services package.
    - Test execution services interfaces and classes
      You use the test execution services interfaces and classes to customize how you run tests. These interfaces and classes are located in the com.ibm.rational.test.lt.kernel package. Each interface and class is described briefly in this topic and in detail in the Javadoc information.
    - Reducing the performance impact of custom code
      If custom code runs inside a page, it can affect that page's response time.
    - Custom code examples
      Custom code enables you to perform such tasks as managing loops, retrieving virtual user information, running external programs from tests, and customizing data correlation.
    - Migrating custom code from previous versions
      You can run scripts that contain custom code from previous releases and edit tests to make new calls to old or new custom code classes.
  - Extending Rational® Performance Tester to support other protocols
    The Rational® Performance Tester Extensibility Software Development Kit (SDK) enables you to create extensions to support testing new protocols without modifying the core product code. You can create an extension that provides functionality for testing other protocols in addition to the HTTP protocol support that is standard in Rational Performance Tester.

Migrating custom code from previous versions

You can run scripts that contain custom code from previous releases and edit tests to make new calls to old or new custom code classes.

About this task

You can perform the following tasks without any additional steps:

Run a script that contains custom code that was created in a previous release.
Edit a test to make a new call to an old custom code class.
Add new custom code to a test that contains old custom code.

To edit a class in existing custom code so that it can call new TestExecutionServices methods, type cast the IKlog argument in the old custom code to the ITestExecutionServices interface.

When you migrate the custom code from the previous versions, you must use getStatisticsManager2() as getStatisticsManager() API is deprecated from 10.1.0.
