PHP unit test automation and continuous integration

PHP unit testing is automated through PHPUnit and can be integrated into continuous integration pipelines to ensure code quality, detect errors early, and improve development efficiency. 1. Install PHPUnit: composer require --dev phpunit/phpunit 2. Create unit test cases: follow the naming convention and write test methods starting with test 3. Automatically execute unit tests: phpunit --filter ExampleTest 4. Continuous integration: use GitHub Actions Other tools automatically run tests every time the code changes

Automatic execution and continuous integration of PHP unit tests

In software development , unit testing is a crucial step in verifying that a block of code works as expected. Automating and integrating unit tests into your continuous integration (CI) pipeline can significantly improve code quality and development productivity.

PHPUnit installation

To perform PHP unit testing, you first need to install PHPUnit. Run the following command:

composer require --dev phpunit/phpunit

Create a unit test case

When creating a test case, you can follow the following naming convention:

TestClassNameTest.php

For example:ExampleTest.php

The methods contained in the test case should start withtest, followed by the description of the method:

/** * Test that adding two numbers returns the correct sum. */ public function testAddNumbers() { // ... }

Automatic execution of unit tests

To automatically execute tests, you can use PHPUnit'sphpunitcommand. This command can be used in conjunction with parameters, such as filtering which tests to run:

phpunit --filter ExampleTest

Continuous Integration

To automatically run tests every time the code changes, PHPUnit can Integrated into continuous integration pipeline. The following is an example of using GitHub Actions:

jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - uses: shivammathur/setup-php@v2 with: php-version: '8.0' - run: composer install - run: vendor/bin/phpunit

Practical case

Example PHP unit test case for testing a simple addition function:

assertEquals(5, $calculator->add(2, 3)); } }

By integrating unit test automation and continuous integration, you can ensure code quality, detect errors early, and improve the efficiency of your development team.
