Test Execution Specialist Guide
This guide describes tasks that you can perform on schedules, test execution with custom code, and Extending HCL OneTest™ Performance to support other protocols. This guide is intended for testers or test execution specialists.
Extending HCL OneTest™ Performance to support other protocols
The HCL OneTest™ Performance 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 HCL OneTest Performance.
Extending the test generation framework
Test generation consists of processing the recorded data and producing a test.
Migrating test generator implementations from previous versions
The new test generation framework builds on the improvements that were made in the recording framework. These improvements include the ability to record several protocols at the same time, which in turn supports generating a single test with mixed protocols. The test generation framework also includes improvements in efficiency and scalability.

Test Execution Specialist Guide
This guide describes tasks that you can perform on schedules, test execution with custom code, and Extending HCL OneTest™ Performance 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.
- Extending HCL OneTest™ Performance to support other protocols
  The HCL OneTest™ Performance 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 HCL OneTest Performance.
  - Protocol extension structure
    Before organizing your extension, note the restrictions and guidelines provided in this topic.
  - Extending the test recorder
    To generate a test, the data exchanged by an application and another entity such as a server must be recorded. The recorded data is then processed to generate a test.
  - Extending the test generation framework
    Test generation consists of processing the recorded data and producing a test.
    - Defining a new test generator
      A test generator uses recorder packets and produces test-model elements that the test generator adds to the test model.
    - Defining a new packet converter
      A packet converter transforms a stream of recorder packets. Use packet converters for adapting the raw data that recorders capture into a suitable format for the test generators to use.
    - Generating tests without a UI
      To test converters and test generators during the development process, you can run them before any UI component is ready for launching them.
    - Defining a test-generation wizard
      The Generate Test wizard contains four sections to guide you in defining a test generator.
    - Migrating test generator implementations from previous versions
      The new test generation framework builds on the improvements that were made in the recording framework. These improvements include the ability to record several protocols at the same time, which in turn supports generating a single test with mixed protocols. The test generation framework also includes improvements in efficiency and scalability.
  - Contributing annotations
    An annotation is an action that a user performs during a recording session. Annotations are used to document or structure the test generated from the recording.
  - Extending the load test behavior model
    The load test behavior model (LTBM) is a model of the behavior of a performance test in HCL OneTest™ Performance.
  - Extending data correlation
    Data correlation is the process of extracting data that is returned from a server, and then sending it back to the server in a subsequent request.
  - Extending the test editor
    The performance testing software provides application programming interface (API) classes for extending the test and performance tools platform (TPTP) to write new editors and protocol extensions.
  - Contributing error handlers
    An error handler is associated with an error condition. Error handlers specify the action to take when a specified error condition occurs. Error handlers are provided for conditions such as verification-point failures, connection failures, server timeouts, and data-correlation problems. You can add new types of errors and error handlers.
  - Extending the schedule component
    When you extend the schedule component in performance testing, another plug-in can contribute options to a schedule. Those options can be set up to persist in the schedule model, and a corresponding user interface can be displayed for editing the new options.
  - Extending code generation
    The code generation subsystem maps Load Test Behavior Model (LTBM) elements to objects of the code generation element model (IModelElement), which in turn are mapped to objects of its ILanguageElement class. As a result, a language element tree is created that contains all equivalent elements of the behavior model test element tree and at the same time determines the structure of code to be generated.
  - Extending the run-time environment
    The run-time environment defines the plug-ins on which all other plug-ins depend. The run-time environment is responsible for defining a structure for plug-ins and the implementation detail behind them.
  - Extending the test log viewer
    After running a test, the test results are saved in a test log. Use the Test Log viewer to check the results for specific events, such as the script start and end, loop, invocation, message, or verdict.
  - Extending evaluation results
    Reports are a specification of how performance test data should be extracted from the statistical model and presented to the user.

Migrating test generator implementations from previous versions

The new test generation framework builds on the improvements that were made in the recording framework. These improvements include the ability to record several protocols at the same time, which in turn supports generating a single test with mixed protocols. The test generation framework also includes improvements in efficiency and scalability.

The test generation API has been completely redefined. You must refactor existing extension code to use the new framework. The following tables summarize the changes to classes and methods in the new test generation framework.

Previous class	Current® class	Comments
com.ibm.rational.test.lt.testgen.core2. IC2ProtocolHandler	com.ibm.rational.test.lt.testgen.core.testgen. BaseTestGenerator	The class no longer has to determine whether it supports a packet type. The framework sends to the test generator only packets that are declared to be supported by the test generator in the plugin.xml file. Previously, protocol handlers loaded messages, then processed them in the process() method. In the new framework, packets are passed one-by-one to the process() method. The process() method generates model elements without delay. The complete() method is available for any post processing.
