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

A collection of one or more test cases is referred to as a test suite. This term is commonly used in software testing to group together related test cases that share the same objective or test a specific feature. The organization of test cases into a suite allows for better management, execution, and reporting on testing activities.

By leveraging test suites, testers can execute tests in a structured manner, ensuring comprehensive coverage of functionality by running all relevant test cases at once. Test suites can also facilitate easier updates and maintenance as new test cases are added or existing ones modified.

The other terms—test design, test methodology, and test plan—serve different purposes within the realm of software testing. Test design pertains to the process of defining how testing will be conducted, test methodology outlines the overall approach and frameworks used for testing, and a test plan details the scope, approach, resources, and schedule of intended testing activities. These concepts, while integral to the testing process, do not specifically refer to collections of test cases.
