Soak testing involves testing a system with a significant load extended over a significant period of time, to discover how the system behaves under sustained use.For example, in software testing, a system may behave exactly as expected when tested for 1 hour. However, when it is tested for 3 hours, problems like 'memory leak' may cause the system to fail or behave randomly.
this soak testing is also know as recovery testing or realiability testing.During these testing TE validates where the application build recovers from abnormal situation to normal situation or not. for examples while taking print out just remove the cabel of the printer and see whether the application is validating it with proper error message.
