Which term describes a collection of one or more test cases?

The term "test suite" is defined as a collection of one or more test cases that are grouped together. This grouping typically occurs because the test cases are related in some manner, perhaps testing the same functionality or feature of an application. Organizing test cases into a suite facilitates easier management, execution, and reporting of testing activities.

A test suite allows testers to run a set of related test cases simultaneously, streamlining the testing process and enabling quick validation of related functionalities. This approach is especially beneficial in agile methodologies, where iterative testing and feedback are crucial for ensuring that changes are continuously validated against established criteria.

In contrast, the other terms have distinct meanings. "Test design" refers to the process of creating test cases based on requirements and specifications, while "test methodology" encompasses the overall approach or framework used in testing (such as Agile, Waterfall, etc.). A "test plan" is a comprehensive document outlining the testing strategy, including objectives, scope, resources, schedule, and risk analysis. Each of these terms serves a specific purpose within the context of software testing, but none of them specifically represent a collection of test cases like a test suite does.
