What is the role of a test suite in automated testing?

A test suite in automated testing is a collection of tests grouped by logical criteria to verify a specific functionality or module of an application. Its role is to organize and simplify the execution of multiple tests simultaneously, allowing for efficient quality assurance and quick defect detection.

Example: a test suite may include all tests related to user authorization — checking correct login, handling incorrect data, password recovery, etc. Running such a suite enables testing all authorization functionalities with a single action.
