There is lot of differences between Load / Stress and Performance testing.The main Scenario of load test is that how many users can access the application at the Same time. Test done with ?N? of Testers or Load Runner is Automation toolStress testing deals with the quality of the application in the environment. The idea is to create an environment more demanding of the application than the application would experience under normal work loads To find defects like: Memory leak, Application hang Test based ? What point the system?s response time degrades or fails.Web Application testing too (WAPT) is Automation toolThanks,Sumanth

Load Testing = If an application can handle 1000 users and by automated software we produce 1000 virtual user to use the application concurrently then this type of Testing is known as Load Testing.

Stress testing = If an application can handle 1000 users and by automated software we produce 2000 virtual user to use the application concurrently then this type of Testing is known as Stress Testing.

Performance testing = In Performance testing we check the response time of the application that how fast the application responses when a Load or Stress is put on the application. Basically Performance Testing= Load Testing + Stress testing.

Suppose an application is used by 50 users, performing 20 transactions per day, supported by 5 servers.

1) increase the number of users to 500.. can the application handle the additional load ?? - this is an example of Load Testing.

2) reduce the number of servers from 5 to 3.. can the remaining servers handle the same volume of transactions ?? - this is an example of Stress Testing. Stress testing is usually performed to see if the application breaks or not.

3) for the original number of users and servers, increase the number of transations per day from 20 to 200.. how does the application behave w.r.t say reponse time ?? - this is an example of Performance Testing.

Thank You. Please correct if wrong.
