Écrire des tests unitaires

Écrire des tests avec des scripts, des fonctions ou des classes, appliquer des dispositifs de test et paramétrer les tests

Écrivez des tests avec le Unit Testing Framework MATLAB^® pour vérifier que les sorties des scripts, fonctions ou classes MATLAB sont conformes à vos attentes. Par exemple, vous pouvez vérifier que les valeurs de sortie réelles correspondent à celles attendues ou que les sorties sont de la taille et du type prévus.

Le Unit Testing Framework vous permet d’écrire des tests avec des scripts, des fonctions ou des classes :

Les tests basés sur des scripts offrent des fonctionnalités de création de tests de base. Vous pouvez effectuer des qualifications de base en utilisant la fonction assert dans vos scripts de test.
Les tests basés sur des fonctions suivent la philosophie de test xUnit et offrent des fonctionnalités étendues de création de tests. Par exemple, vous disposez de capacités de qualification avancées comprenant des contraintes, des tolérances et des diagnostics de test.
Les tests basés sur des classes vous donnent accès à l’ensemble des fonctionnalités du framework. Par exemple, vous pouvez utiliser des dispositifs de test partagés, paramétrer les tests et réutiliser leur contenu.

Rubriques

Écrire des tests basés sur des classes

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
Specify setup and teardown code that runs before and after each Test method or all Test methods in a test class.
Write Tests Using Shared Fixtures
Share fixtures across test classes 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.
Insert Test Code Using Editor
Write a parameterized test interactively by using the options in the MATLAB Editor.
Table of Verifications, Assertions, and Other Qualifications
Test values and respond to failures using verifications, assumptions, assertions, and fatal assertions.
Ways to Write Unit Tests
Choose a test authoring scheme that best suits your requirements and your preferred workflow.

Écrire des tests paramétrés

Use Parameters in Class-Based Tests
Use parameters to provide data for your tests to use iteratively.
Create Basic Parameterized Test
Test a function by creating a test that is parameterized in the Test methods block.
Create Advanced Parameterized Test
Create a test that is parameterized in the TestClassSetup, TestMethodSetup, and Test methods blocks.
Define Parameters at Suite Creation Time
Use a TestParameterDefinition method 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.

Écrire des tests basés sur des fonctions

Write Function-Based Unit Tests
A 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.
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.

Écrire des tests basés sur des scripts

Write Script-Based Unit Tests
Write a script to test a function that you create.
Write Test Using Live Script
Write a live script that tests a function that you create.
Write Script-Based Test Using Local Functions
Write a script-based test that uses local functions as helper functions.
Extend Script-Based Tests
Access additional functionality using script-based tests, including test selection, programmatic access of test diagnostics, and test runner customization.
