Class-Based Unit Tests

Write class-based tests; parameterize tests; apply fixtures; select and run 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 get started, seeAuthor Class-Based Unit Tests in MATLABandWrite Simple Test Case Using Classes.

Topics

Write Tests

Author Class-Based Unit Tests in MATLAB
To test a MATLAB program, write a unit test using qualifications that are methods for testing values and responding to failures.
Write Simple Test Case Using Classes
Write class-based unit tests to determine the correctness of your program.
Write Setup and Teardown Code Using Classes
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.
Write Tests Using Shared Fixtures
You can share test fixtures across test classes. This example shows how to use shared fixtures when creating tests.
Tag Unit Tests
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.
Table of Verifications, Assertions, and Other Qualifications
Test values and respond to failures using verifications, assumptions, assertions, and fatal assertions.

Write Parameterized Test

Use Parameters in Class-Based Tests
Use parameters to provide data that should be used iteratively by your tests.
Create Basic Parameterized Test
Test a function by creating a test that is parameterized in theTestmethodsblock.
Create Advanced Parameterized Test
Create a test that is parameterized in theTestClassSetup,TestMethodSetup, andTestmethodsblocks.
Define Parameters at Suite Creation Time
Use aTestParameterDefinitionmethod to define parameters at test suite creation time.
Use External Parameters in Parameterized Test
Use data-driven testing to inject variable inputs into your parameterized test.

Run Tests and Analyze Results

Create Simple Test Suites
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 Tests for Various Workflows
Explore different ways to run tests.
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 asIncompleteinstead of producing test failures. To avoid test code that is not executed, monitor the filtered tests.
Programmatically Access Test Diagnostics
Programmatically access the diagnostics that the testing framework records on test results.
Add Plugin to Test Runner
This example shows how to add a plugin to the test runner.
Generate Code Coverage Report in HTML Format
Generate and analyze statement and function coverage metrics for your MATLAB source code.
Compile MATLAB Unit Tests
Create a standalone application to run your tests on target machines that do not have MATLAB installed.
