Introduction

Laravel provides a very fluent API for making HTTP requests to your application, examining the output, and even filling out forms. For example, take a look at the test defined below:

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function testBasicExample()
    {
        $this->visit('/')
             ->see('Laravel 5')
             ->dontSee('Rails');
    }
}

The visit method makes a GET request into the application. The see method asserts that we should see the given text in the response returned by the application. The dontSee method asserts that the given text is not returned in the application response. This is the most basic application test available in Laravel.

You may also use the 'visitRoute' method to make a 'GET' request via a named route:

$this->visitRoute('profile');

$this->visitRoute('profile', ['user' => 1]);

Interacting With Your Application

Of course, you can do much more than simply assert that text appears in a given response. Let's take a look at some examples of clicking links and filling out forms:
