How to use Laravel Input::replace() in testing POST requests
http-post, laravel, php, unit-testing
Solution
You should use `Request::replace()`, not `Input::replace` in order to replace input data for the current request.
Problem
I'm having some trouble using Laravel's `Input::replace()` method to simulate a POST request during unit testing. According to Jeffrey Way here and here, you can do something like this: ``` # app/tests/controllers/PostsControllerTest.php public function testStore() { Input::replace($input = ['title' => 'My Title']);</p> $this->mock ->shouldReceive('create') ->once() ->with($input); $this->app->instance('Post', $this->mock); $this->call('POST', 'posts'); $this->assertRedirectedToRoute('posts.index'); } ``` However, I can't get this to work. `Input::all()` and all `Input::get()` calls still return an empty array or null after `Input::replace()` is used. This is my test function: ``` public function test_invalid_login() { // Make login attempt with invalid credentials Input::replace($input = [ 'email' => 'bad@email.com', 'password' => 'badpassword', 'remember' => true ]); $this->mock->shouldReceive('logAttempt') ->once() ->with($input) ->andReturn(false); $this->action('POST', 'SessionsController@postLogin'); // Should redirect back to login form with old input $this->assertHasOldInput(); $this->assertRedirectedToAction('SessionsController@getLogin'); } ``` The `$this->mock->shouldReceive()` doesn't get called with `$input` though - it only gets an empty array. I've confirmed this in the debugger by looking at `Input::all()` and `Input::get()` for each value, and they're all empty. TL/DR: How do I send a request with POST data in a Laravel unit test?
