3What is Load testing?
4Load testing is the process that simulates
5actual user load on any application or website.
6It checks how the application behaves during normal
7and high loads. This type of testing is applied
8when a development project nears to its completion.
9Load testing is performed to determine how many
10users the system can handle.

12What is Stress testing?
13Stress testing is testing that checks the upper
14limits of your system by testing it under extreme loads. 
15Stress testing is a type of testing that determines
16the stability and robustness of the system. 
17It is a non-functional testing technique.
18This technique uses auto-generated simulation
19model that checks all the hypothetical scenarios.

21When do you use Performance Testing?
22Performance testing is done to check the
23performance of website servers, database, and network.
24If you are adopting waterfall methodology,
25then it is important for you to check each time
26release of a new version. However,
27if you are using the agile software development approach,
28then you need to test application continuously.
