# What is a Test Suite?

A **test suite** is a **collection of related test cases** that are grouped together and executed as a set.

### Example

Imagine you're testing an e-commerce website.

You might have:

**Login Test Suite**

* TC01 – Login with valid username/password
* TC02 – Login with invalid password
* TC03 – Login with empty username
* TC04 – Login with empty password
* TC05 – Logout

All these related test cases form a **test suite**.
