Don’t skip the unit testing and build better Laravel apps

Unit testing is crucial in software development, ensuring your application’s components work as expected in isolation. By writing tests for specific code units, you can identify and fix errors early in development, leading to more reliable and stable software.

In a continuous integration/continuous delivery (CI/CD) pipeline, you can run these tests automatically after making codebase changes. This ensures that new code doesn’t introduce errors or break existing functionality.

This article highlights the importance of unit testing in Laravel applications, detailing how to write unit tests for a Laravel application deployed using Kinsta’s Application Hosting service.

Introduction to PHPUnit

PHPUnit is a widely used testing framework within the PHP ecosystem designed for unit testing. It has a robust suite of tools for creating and running tests, making it a critical resource for ensuring your codebase’s reliability and quality.

Laravel supports testing with PHPUnit and ships with convenient helper methods that let you test your application.

Setting up PHPUnit in a Laravel project involves minimal configuration. Laravel provides a preconfigured testing environment, including a phpunit.xml file and a dedicated tests directory for your test files.

Alternatively, you can modify the phpunit.xml file to define custom options for a tailored testing experience. You can also create a .env.testing environment file in the project’s root folder instead of using the .env file.
