Performance testing determines the entire functionality of a website or an application by testing its operability under stress and load. There are three major types of performance testing, namely:
Load Testing: It involves the activity of a website or application by loading several data on the system.
Stress Testing: It determines the behavior of a site or application when it reaches its peak due to the amount of load on the system.
Capacity Testing: This helps provide detailed information about how much the website or application can handle, including when the response time becomes flawed.
