Difference between Performance, Load and Stress Testing

NO	Performance Testing	Load Testing	Stress Testing
1	It is testing to determine how the system perform in given particular situation	It is testing to determine the behavior of the system under a specific expected load	It is testing to determine the behavior of the system after increasing upper limit within system
2	The Main goal of the Performance testing to find out the accuracy and close monitoring of the performance and result	The main goal of the Load testing to find the defect in application like memory leak, buffer overflow etc.	The main goal of the stress testing in to analyze the post crash reports to define behavior of the application after specific failure
3	-	Load Testing also called as Volume testing and Endurance Testing	Stress testing is also Known as Fatigue testing
4	Performance testing  check that how fast the Application is?	Load testing  check that  how much volume can be application process?	Stress testing is check how Application recover gracefully after crashes/Stress?
