How to Get Started with PestPHP

To get started with PestPHP, you can install it using the Composer package manager:

composer require pestphp/pest --dev --with-all-dependencies

Once PestPHP is installed, you can create a new test directory for your project:

Now, you'll need to initialize Pest in your current PHP project. This step will create a configuration file named Pest.php at the root level of your test suite, which will enable you to fine-tune your test suite later.

./vendor/bin/pest --init

Writing Your First PestPHP Test

To write your first PestPHP test, you can use the following

it('should pass', function () {
 // Your test code goes here.
}) ;

Or this syntax

test('sum', function () {
   $result = sum(1, 2);

   expect($result)->toBe(3);
});

The it() function defines a test case. The first argument to the it() function is a human-readable description of the test case. The second argument to the it() function is a callback function that contains your test code.

You can run your tests by executing the following command.

./vendor/bin/pest

Pest will discover all of your tests and run them. If any of your tests fail, Pest will provide you with a detailed error message.

Conclusion

PestPHP is a modern PHP testing framework that is simple to use, elegant, and expressive. It is a good choice for any PHP project that needs to be tested.
