3. Stress Testing. Stress testing measures software performance beyond the normal working parameters. It means the software is placed under higher traffic loads (more users, transactions, etc.) to help developers learn how well the software performs above its capacity limits expectedly. The goal of this testing is to determine the software's ...
Grinder 3 allows codes like Java, Jython, and Clojure to get encapsulated as a test. Moreover, Grinder can use Java libraries that are meant for a number of systems and protocols. Grinder 2 processes execute tests in a sequential fixed order. Grinder 3 allows random branching and looping and makes the test results available for the test scripts.
The Grinder load testing framework is a good tool for stress testing your website or application. It can run tests in parallel on multiple machines, allowing you to check how your application would behave under heavy load. This makes it possible to determine your app's weak points, so you can proceed to optimize them.
Stress testing is a type of non-functional testing and is usually done after the functional testing. When there is a requirement of load testing as well, then this testing can be done as the extreme case of load testing. 90% of the time, the same automation tool can be used for both load and stress testing.
