Performance Testing

Verify the application Behavior by applying load is known as performance testing.

- Generally in it defines how quickly server respond to the user's request.

- We will do performance testing when application is stable and moved to the production.

Speed – Determines whether the application responds quickly..

Scalability – Determines the maximum user load the software application can handle.

Stability – Determines if the application is stable under varying loads.

Types of Performance Testing -

Load Testing -

increasing the load on the application slowly then check the speed of app

Stress Testing -

suddenly we incrase or decrase the load and then check the applicatuon speed.

Scalability testing -

Checking the performance of an application by increasing or decreasing the load in particular scales (no of a user) is known as scalability testing.

Scalability Testing Divida in two parts:

- Upward scalability

- Downward scalability

Volume Testing

- it Defies how much the data should able to stored the application.

- Volume testing determines how efficiently software performs with large projected amounts of data.

- It is also known as flood testing because the test floods the system with data.
