Performance Testing identifies the stability of the application and tests the speed of the product response with different types and intensity of load. The purpose of testing is the identification of the disadvantages and vulnerabilities in the system, identification of the data downloading and processing speed and reliability of the program.
Testing of system parameters can be done using:
- determination of the permissible number of application users;
- measurement of the execution time of a system operation;
- determination of permissible program performance limits with different load levels.
Performance testing can be divided into the following subtypes:
- load testing;
- stress testing;
- stability testing;
- configurational testing.
