Function-Based Unit Tests
Write function-based tests to check that the outputs of MATLAB® scripts, functions, or classes are as you expect. You can use a full library of qualification functions to produce four different types of test failures. For example, you can produce verification or fatal assertion test failures. Function-based tests subscribe to the xUnit testing philosophy.
For more advanced test authoring, including using test parameterization and test fixtures, consider writing Class-Based Unit Tests.

- Write Function-Based Unit Tests
Your test function is a single MATLAB file that contains a main function and your individual local test functions. Optionally, you can include file fixture and fresh fixture functions.
- Write Simple Test Case Using Functions
Write function-based unit tests to determine the correctness of your program.
- Write Test Using Setup and Teardown Functions
Write a function-based test with setup and teardown functions that run once in your test file and before and after each test function in the file.
- Table of Verifications, Assertions, and Other Qualifications
Test values and respond to failures using verifications, assumptions, assertions, and fatal assertions.
Run Tests and Analyze Results
- Run Tests for Various Workflows
Explore different ways to run tests.
- Run Tests Using Test Browser
Run your tests interactively by using the test browser. (Since R2023a)
- Run Tests in Editor
Run your tests while working in the Editor or Live Editor.
- Analyze Test Case Results
This example shows how to analyze the information returned by a test runner.
- Analyze Failed Test Results
This example shows how to identify and handle failed tests.
- Rerun Failed Tests
Rerun failed tests quickly and conveniently.
- Dynamically Filtered Tests
Assumption failures produce filtered tests that are marked as
Incompleteinstead of producing test failures. To avoid test code that is not executed, monitor the filtered tests.
- Extend Function-Based Tests
Access additional functionality using function-based tests, including application of fixtures, test selection, programmatic access of test diagnostics, and test runner customization.
