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.
Testing with Docker images
IBM® Rational® Performance Tester, IBM Rational Functional Tester, and IBM Rational Performance Tester Agents are available for download as Docker images. You can use them to fulfill the continuous testing aspects of your DevOps lifecycle.

Test Execution Specialist Guide

- 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.
  - Running a local schedule or test
    You can run a test locally or a schedule, in this context, is used to refer to both VU Schedule and Rate Schedule on remote locations with a default launch configuration.
  - Running a long run mode SAP GUI test
    When running a SAP GUI test that could last for many hours and could use up the operating system resources, you can choose to run the test with the Long Run Mode process. It is an external process that restarts automatically after the specified number of SAP sessions are over. So, tests of longer duration tests are more likely to finish.
  - Running long duration Citrix tests
    When tests exceed many hours, resource consumption issues can cause problems for the Citrix clients. The long run mode increases the reliability of long duration tests with the Citrix protocol by running the test using multiple processes.
  - Testing with Docker images
    IBM® Rational® Performance Tester, IBM Rational Functional Tester, and IBM Rational Performance Tester Agents are available for download as Docker images. You can use them to fulfill the continuous testing aspects of your DevOps lifecycle.
    - Running tests with containerized agents
      When you have a local workbench, instead of installing the agents on different machines and locations, you can deploy the containerized agents to generate the load.
    - Running automated tests with containerized workbench and agents from Docker
      To simplify the deployment piece of Continuous Testing, you can use built Docker images to deploy the workbench and the agents and start testing in no time. You need not install the workbench and the agents on different machines. You can deploy the Docker images and use Docker commands to play back tests.
  - Testing with IBM Cloud Private
    You can automate your testing environment by using Docker container images of the workbench and agents on top of IBM® Cloud Private.
  - Adjusting delays in HTTP tests
    You can configure HTTP tests to use client-side processing delays. Client-side processing delays wait for the first character or last character that is received in a response for a previous request in order to better emulate the work done on the client computer. You can also scale the recorded delays in HTTP tests to change the rate at which a test runs.
  - Setting a launch configuration
    Instead of using the default launch configuration, you can specify the file name for the execution results, the name of the folder for the execution results, and, for a test, the number of users.
  - Running a configured schedule
    If you do not use the default launch configuration, you can configure the schedule and then run it.
  - Configuring multiple host names for a location
    You can run several locations on the same computer by configuring multiple host names for a location. This configuration affects all tests running at that location; all tests will run with the configured port.
  - Automating tests from command line
    You can run a schedule from the command line. You can also set preferences to export results after the run completes from the command line or from the workbench. Together, these features let you run tests and analyze results without opening the workbench. You can even write scripts to process the exported results.
  - Controlling caches size
    If you use an infinite loop and the number of cached responses in a test increases exponentially, you can set a limit to cache for a user group in the schedule.
  - Increasing memory allocation
    The virtual users that access your web server require memory to prepare requests, send requests, and receive responses. Because the amount of memory is not automatically set on remote computers, you might receive an out-of-memory error. To correct this situation, increase the memory allocation for that computer.
  - Controlling execution of web analytic reports
    When a schedule is in the running state, you can perform the following actions from the web analytics reports to cater to your need.
  - Debugging HTTP tests
    If a test does not behave as expected during playback, you can use the protocol data and test log to assist in debugging the test.
  - Debugging Citrix tests
    The Citrix dashboard is an optional panel that displays detailed information and control commands for each virtual user during the run of a schedule. This is useful for debugging your tests and allows you to pause, interact, resume, or stop the execution of individual virtual user sessions.
- 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 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.

Testing with Docker images

IBM® Rational® Performance Tester, IBM® Rational® Functional Tester, and IBM® Rational® Performance Tester Agents are available for download as Docker images. You can use them to fulfill the continuous testing aspects of your DevOps lifecycle.

You must use only floating licenses for the product and VT-pack when playing back tests using Docker. These licenses should be hosted on a server that can be accessed by the workbench.
