Why Performance…?Does the application respond quickly enough
for the intended users?Will the application handle the expected user
load and beyond?Will the application handle the number of
transactions required by the business?Is the application stable under expected and
unexpected user loads?Are you sure that users will have a positive
experience on go-live day?

Define Stress/Load/Performance TestingStress Testing: Stress Testing is done in order to
check when the application fails by varying the system resources such as RAM, HDD etc. and keeping the number of users as constant.
Load Testing: Load Testing is done in order to check when the application fails by increasing the number of users and keeping the system resources as constant.
Performance Testing: The term Performance can mean measuring response time, number of hits , resource utilization, or some other system characteristic( or group of them), by varying the number of users.
