Load and stress test component

Tom deMarco: "You cannot control what you cannot measure."

Load and stress tests belong to the non-functional test category and are used to validate the system under test at varying degrees of load.

As an example one would use a stress test to determine the maximum amount of simultaneous users the system is able to handle inside a given parameter range. Load tests allow to simulate realistic user behavior to test the expected server load before placing a production system online.

With PETA-Load you are able to simulate thousands of user requests in parallel which reenact different business use-cases to validate your hardware configurations prior to going live of the system under test.

The PETA-Webrecorder helps you to generate a large amount of test cases in short time.

Load testsStress tests
  • How does the software perform in case of a large amount of users?
  • How does the software perform with a large amount of data to process?
  • Where and when do performance problems arise?
  • Does the system work as specified?
  • Is the hardware adequately dimensioned for peak load situations?
  • Does the software still work when reaching the specified boundary conditions? Where are the limits of the system?
  • Is the system recovering correctly from overload situations?
  • Does the software correctly handle overload scenarios? Is the stored data still consistent?
  • How does the throughput of the system scale with better hardware?



  • Already implemented functional tests can be applied for load scenarios on the system under test.


  • For load generation it is possible to employ single load clients as well as clusters of client machines.

Platform independence

  • PETA-Load allows the combined use of load clients on different platforms.

Extensive reporting

  • Customizable graphical evaluation of log files.
