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.
About this task
The following guidelines improve the success of long duration tests:
- Use agent computers with at least 2GB of RAM and 10GB of free disk space, running the same version of the IBM® Rational® Performance Tester or Rational Performance Tester Agent.
- Disable antivirus software, screen savers, and automatic updaters on the agent computers during the test.
- Keep individual tests short by having loops of not more than 10 iterations within each test. Get the desired long run duration by looping within the schedule. Do not exceed 20 or 30 virtual testers for each agent computer with a think time of more than several seconds.
- Use tests with a minimal number of verification points.
- Do not use the Signature theme. Disable all animations in the SAP GUI.
- Do not use the mouse during the test. Any mouse click could be interpreted by a hidden SAP GUI window, which could cause the test to fail.
- Ensure that the Screen Throughput counter remains low (approximately 1 every second for each agent).
- Before playing back a test, in SAP Connection Details editor, click Test Connection to test the connection to the SAP GUI server.
