Escribir pruebas unitarias

Escriba pruebas utilizando scripts, funciones o clases; aplique accesorios; parametrice pruebas

Escriba pruebas utilizando el marco de pruebas unitarias de MATLAB^® para comprobar que las salidas de los scripts, funciones o clases de MATLAB son las que espera. Por ejemplo, puede comprobar que los valores de salida reales coincidan con los valores esperados o puede comprobar que las salidas tengan el tamaño y tipo esperados.

El marco de pruebas unitarias permite escribir pruebas utilizando scripts, funciones o clases:

Las pruebas basadas en scripts proporcionan una funcionalidad básica de creación de pruebas. Puede realizar calificaciones básicas usando la función assert en los scripts de prueba.
Las pruebas basadas en funciones siguen la filosofía de pruebas xUnit y proporcionan una amplia funcionalidad de creación de pruebas. Por ejemplo, puede utilizar prestaciones avanzadas de calificación, incluidas restricciones, tolerancias y diagnósticos de pruebas.
Las pruebas basadas en clases le brindan acceso a todas las funcionalidades del marco. Por ejemplo, puede utilizar accesorios de prueba compartidos, parametrizar pruebas y reutilizar el contenido de las pruebas.

Temas

Escribir pruebas basadas en clases

Class-Based Unit Tests
Test your MATLAB source code by creating class-based unit tests.
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.
Write Independent and Repeatable Tests
Write class-based tests following best practices for test independence and repeatability.
Ways to Write Unit Tests
Choose a test authoring scheme that best suits your requirements and your preferred workflow.

Escribir pruebas parametrizadas

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.
