Testing

• Feature
  • A larger portion of the code, how several objects
• Unit
  • Small functionalities (e.g. a function)

Config

• Config: phpunit.xml
  • Need to config:cache after editing

Usage

• Create

// Create a feature test
php artisan make:test XXXTest

// Create a unit test
php artisan make:test XXXTest --unit

A test would looks like:

<?php

namespace Tests\Unit;

use PHPUnit\Framework\TestCase;

use Tests\TestCase // better

class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testBasicTest()
    {
        $this->assertTrue(true);
    }
}

• Run the test

php artisan test [--group name] [/path/to/test.php]

Danger

A facade root has not been set when use things related to the application

<?php

namespace Tests\Unit;

use Tests\TestCase;

class XXXTest extends TestCase
{

}

Danger

The test function name must be testXXX() or you need to add comment @test above the function

/** @test */
public function it_tests_something()
{
  ...
}
