It is important for us to write unit test<\/strong> if we want the codes we developed in a software project to deploy production with the least bugs. Especially if we are going to work in corporate and enterprise companies, we are asked to test the code we have written.<\/p>\n\n\n\n

In this post, I will explain how to write a unit test<\/strong> in PHP Laravel <\/strong>and how to run the written test. Writing a test can feel intimidating and a waste of time at first. But as we get used to test writing and practice, we will improve that skill.<\/p>\n\n\n\n

Laravel comes with the PHPUnit <\/strong>package where we will run the unit tests. PHPUnit is PHP’s unit testing framework.<\/p>\n\n\n\n

First, let’s look at where to write test codes in Laravel. The tests we will write in Laravel are located in the tests <\/strong>folder.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

This folder contains Feature <\/strong>and Unit<\/strong> folders and sample tests in these folders.<\/p>\n\n\n\n

There are 2 methods of running these tests.<\/p>\n\n\n\n

  1. .\/vendor\/bin\/phpunit<\/code><\/li>
  2. php artisan test<\/code><\/li><\/ol>\n\n\n\n
    \"\"<\/figure><\/div>\n\n\n\n

    If we only want to run Unit tests<\/strong>, we run php artisan test --testsuite=Unit<\/code> command on the terminal screen.<\/p>\n\n\n\n

    General settings for the tests to be run in Laravel are made in the phpunit.xml<\/strong> file.<\/p>\n\n\n\n

    Writing Our First Unit Test<\/h3>\n\n\n\n

    In this post, we will write a test for our add_post()<\/strong> method inside our PostsController<\/strong>.<\/p>\n\n\n\n

    public function add_post(Request $request)\n    { \n        $name = $request->title;\n        $content = $request->content;\n        $status = $request->status;\n        \n        $post = Posts::create([\n                'name'=>$name,\n                'content'=>$content,\n                'status' =>$status ?? 0\n            ]);\n       \n        return response()->json($post, 200);\n    }<\/pre><\/div>\n\n\n\n
    Kendi testimizi yazmak i\u00e7in ilk \u00f6nce terminalde php artisan make:test PostTest --unit<\/code> komutlar\u0131n\u0131 \u00e7al\u0131\u015ft\u0131r\u0131yoruz. Unit<\/strong> klas\u00f6r\u00fcn\u00fcn alt\u0131nda olu\u015fan PostTest.php<\/strong> dosyas\u0131na ilk testimizi yazal\u0131m.<\/p>\n\n\n\n
    To write our own test, we first run php artisan make:test PostTest --unit<\/code> commands in the terminal. Let’s write our first test in the PostTest.php<\/strong> file created under the Unit folder.<\/p>\n\n\n\n
    <?php\n\nnamespace Tests\\Unit;\n\nuse Tests\\TestCase;\n\nclass PostTest extends TestCase\n{\n    public function test_add_post()\n    {\n        $response = $this->call('POST', '\/admin\/add-post', [\n            'name' => 'Some post title 123',\n            'content' => 'Some post content 123',\n            'status' => false\n        ]);\n\n        $response->assertStatus($response->status(), 200);\n    }\n}\n<\/pre><\/div>\n\n\n\n
    To run the test, we run the php artisan test<\/code> command in the terminal.<\/p>\n\n\n\n
