软件工程中的测试套件（test suite）有时也称为验证套件（validation suite），是许多测试用例的集合，测试用例可用来测试一程序是否正确工作，测试套件包括许多测试用例，一般也会有针对测试用例及其测试目的的详细说明，在进行测试时的系统组态信息以及测试前需进行的步骤。

测试用例的集合是测试套件，不过常误称为测试计划（test plan）、测试脚本（test script）或是测试场景（test scenario）。

Java语言的单元测试框架JUnit中，就有提供支持测试套件功能的TestSuit对象。

In software development, a test suite, less commonly known as a 'validation suite', is a collection of test cases that are intended to be used to test a software program to show that it has some specified set of behaviours. A test suite often contains detailed instructions or goals for each collection of test cases and information on the system configuration to be used during testing. A group of test cases may also contain prerequisite states or steps, and descriptions of the following tests.
