use PHPUnit\Framework\TestCase; class MyTest extends TestCase { public function __construct() { // Initialize the parent constructor parent::__construct(); // Set any required properties or variables $this->expectedResult = 42; } public function testAddition() { $result = 40 + 2; $this->assertEquals($result, $this->expectedResult); } }
use Illuminate\Foundation\Testing\TestCase as BaseTestCase; class MyTest extends BaseTestCase { public function __construct() { parent::__construct(); $this->expectedResult = 'Hello, World!'; } public function testGreeting() { $result = 'Hello, ' . 'World!'; $this->assertEquals($result, $this->expectedResult); } }In this example, we create a new test case called `MyTest` that extends the `Illuminate\Foundation\Testing\TestCase` class. In the constructor, we initialize the parent constructor and set the `expectedResult` property to `'Hello, World!'`. In the `testGreeting` method, we concatenate two strings and use the `assertEquals` method to compare the result to the `expectedResult`. This example uses the Laravel framework.
