Welcome PHP enthusiasts! Let's continue our exploration of PHP testing with Pest 🐛 In our previous post, we introduced Pest, an elegant PHP testing framework that prioritizes simplicity and readability. If you missed it, you can check it out here.
Recap: Installation and Setting the Stage 🚀
To get started with Pest, we need to install it in our PHP project. If you haven't done so already, follow these steps:
Open your terminal.
Navigate to your project directory.
Run the following command:
composer require pestphp/pest --dev
Great! Now we have Pest installed and ready to go.
Writing Our First Test - The Next Step 📝
Now that we have Pest set up, let's dive into writing our first test. In our previous post, we showed an example of a basic test using Pest. Here it is again as a refresher:
<?php
use ICalcApp\Calculator;
it('should add two numbers correctly', function () {
$calculator = new Calculator();
$result = $calculator->add(2, 3);
assertEquals(5, $result);
});
This test checks if our Calculator class correctly adds two numbers. Pest provides a variety of assertions like assertEquals, assertTrue, assertFalse, assertNotNull, and more. Feel free to explore them and choose the ones that best suit your testing needs.
Going Beyond the Basics - Exploring Advanced Features 🏄♂️
Now that you have a grasp of the basics, it's time to dive deeper into Pest and explore its advanced features. In our previous post, we covered the simplicity and ease of writing tests with Pest. However, Pest has much more to offer. Here are some advanced features you can explore:
- Data Providers: Pest allows you to use data providers to run the same test with different input values. This can be useful for testing edge cases and ensuring your code handles various scenarios correctly.
- Mocking and Stubbing: Pest integrates well with popular mocking libraries like Mockery and Prophecy, allowing you to easily mock dependencies and stub method calls during your tests.
- Code Coverage: Pest provides built-in code coverage reports, allowing you to analyze how much of your code is being tested and identify areas that need more test coverage.
- Test Organization: Pest offers various ways to organize your tests, such as using groups, tags, and test suites. These features can help you manage and run specific sets of tests based on your needs.
These are just a few examples of the advanced features Pest has to offer. As you continue your PHP testing journey, don't hesitate to explore and leverage these features to write comprehensive and effective tests.
