Running Tests

In a load test, multiple virtual users are run by means of a test script against a target server to determine the load impact on server performance. A large load test requires an appropriate testing environment on your LAN, including a full complement of agent computers to host the virtual users.

It is essential that you complete the following tasks:

Set options for the appropriate type of test that is to be run
Accurately define the required workloads
Enable the generation of test results to assess server performance

Do not enable complete result-logging during load testing because it might interfere with load-test results. However, the TrueLog On Error logging option writes necessary log files to a disk when errors occur, allowing you to inspect replay errors visually.

Real-time information regarding agent computers, virtual users, and transactions is displayed for you while load tests run. Real-time performance monitoring of the target server is presented in graphical format.

When a test is configured as a verification run, the following options are automatically set to the specified values:

A Baseline report file is automatically created.
The Stop virtual users after simulation time (Queuing Workload) option is disabled.
The Virtual user log files (.log) option is disabled.
The Virtual user report files (.rpt) option is enabled.
The Virtual user report on error files (.rpt) option is enabled.
The Compute time series data (.tsd) option is disabled.
