Performance Test Automation

 

Performance testing, a non-functional testing technique used to determine the system parameters in terms of responsiveness and stability under various workloads. Performance testing measures the quality attributes of the system, such as scalability, reliability and resource usage.

 

Testing types:

Load testing is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application performing a specific number of transactions within the set duration.

Stress testing is normally used to understand the upper limits of capacity within the system.

Soak testing, also known as endurance testing, is usually done to determine if the system can sustain the continuous expected load. 

 

Spike testing is done by suddenly increasing the load generated by a very large number of users, and observing the behaviour of the system.

 

Configuration testing
Rather than testing for performance from a load perspective, tests are created to determine the effects of configuration changes to the system's components on the system's performance and behavior.

 

Isolation testing involves repeating a test execution that resulted in a system problem. Such testing can often isolate and confirm the fault domain.
