Class-Based Unit Tests
Write xUnit-style tests to check that the output of MATLAB® code is as you expect. Class-based unit tests give you access to the full unit testing framework functionality. For example, you can write parameterized tests, tag your tests, or use shared test fixtures.

To test a MATLAB program, write a unit test using qualifications that are methods for testing values and responding to failures.
Test values and respond to failures using verifications, assumptions, assertions, and fatal assertions.
Write class-based unit tests to determine the correctness of your program.
Setup and teardown code, or test fixtures, sets up the pretest state of the system and returns it to the original state after running the test. You can define setup and teardown methods that run before and after each test method or all test methods in a test class.
Use test tags to group tests into categories and then run tests with specified tags. Typical test tags identify a particular feature or describe the type of test.
You can share test fixtures across test classes. This example shows how to use shared fixtures when creating tests.
Write Parameterized Test
Use parameters to provide data that should be used iteratively by your tests.
Test a function by creating a test that is parameterized in the
Create a test that is parameterized in the
TestParameterDefinition method to define parameters
at test suite creation time.
Use data-driven testing to inject variable inputs into your parameterized test.
Run Tests and Analyze Results
This example shows how to combine tests into test suites, whether they are organized in packages and classes or files and folders, or both.
Run your tests while working in the Editor or Live Editor.
Explore different ways to run tests.
Programmatically access the diagnostics that the testing framework records on test results.
This example shows how to add a plugin to the test runner.
This example shows how to analyze the information returned by a test runner.
This example shows how to identify and handle failed tests.
Rerun failed tests quickly and conveniently.
Assumption failures produce filtered tests that are marked as
Incomplete instead of producing test failures. To avoid test code that is not executed, monitor the filtered tests.
Create a standalone application to run your tests on target machines that do not have MATLAB installed.
