Why Bother

for full story on why this package was built please refer to This Blog Post

Installation

1. Using composer

composer require --dev mohammedmanssour/form-request-tester

2. add MohammedManssour\FormRequestTester\TestsFormRequests trait to your test case.

Testing a form request

1. you need to intialize the form request using formRequest method, it takes the FormRequest class as first argument and an array of request data as a second argument

$this->formRequest(UpdatePost::class, [
    'title' => 'New Title',
    'content' => 'Some Content here'
])

or you can use the intuitive methods to set form request method and data

$this->formRequest(UpdatePost::class)
->post([
    'title' => 'New Title',
    'content' => 'Some Content here'
])

the previous code will intialize the request with post method and /fake-route if you want to change these options you can via the options array that can be set as a third argument

$this->formRequest(UpdatePost::class, [
    'title' => 'New Title',
    'content' => 'Some Content here'
], [
    'method' => 'put',
    'route' => 'posts/{post}'
])

$this->formRequest(UpdatePost::class)
->put([
    'title' => 'New Title',
    'content' => 'Some Content here'
])
->withRoute('posts/{post}')

2. use the available assertions to test for request

Available Assertions

$this->assertValidationPassed()	To make sure the validation have passed successfully with the help of the provided data.
$this->assertValidationFailed()	To make sure the validation have failed with the help of the provided data.
$this->assertValidationErrors($keysArray)	To assert that the keys mentioned in the $keysArray have occurred in the errors bag.
$this->assertValidationErrorsMissing($keysArray)	To assert that the keys mentioned in the $keysArray have not occurred in the errors bag.
$this->assertValidationMessages($messagesArray)	To assert that the messages exists in the error bag. Used when you define custom messages for your validation.
$this->assertAuthorized()	To assert that request have been authorized via the form request.
$this->assertNotAuthorized()	To assert that request have not been authorized via the form request.
$this->assertValidationData($keysArray)	To assert that the keys mentioned in the $keysArray have occurred in the validated data.
$this->assertValidationDataMissing($keysArray)	To assert that the keys mentioned in the $keysArray have not occurred in the validated data.

Example Usage:

Taking into consderation:

1. title & content are required field,
2. Content field is required is a custom error message used for content field
3. $this->route method is used in authorize method
4. Route::put('posts/{post}', 'PostsController@update') is the route used to update a post

$this->formRequest(UpdatePost::class,[
    'title' => 'New Title'
],[
    'method' => 'put'
    'route' => 'posts/{post}'
])->assertAuthorized()
->assertValidationFailed()
->assertValidationErrors(['content'])
->assertValidationErrorsMissing(['title'])
->assertValidationMessages(['Content field is required'])

you can now use intuitive methods to build form request

$this->formRequest(UpdatePost::class)
->put([
    'title' => 'New Title'
])
->withRoute('posts/1')
->assertAuthorized()
->assertValidationFailed()
->assertValidationErrors(['content'])
->assertValidationErrorsMissing(['title'])
->assertValidationMessages(['Content field is required'])

Form Requests related methods and how to work with them

$this->route('parameter'):

This method basically retreive the value of a routing rule parameter.

For example if you have a routing rule put posts/{post} and browsed to posts/1 then the value of $this->route('post') is 1. for this to work with the package you need to

1. Register the routing rule in your application routing files web.php or api.php

Route::put('posts/{post}', [PostsController::class, 'update']);

2. set the route using FormRequestTester withRoute method

$this->formRequest(UpdatePost::class)
    ->put($data)
    ->withRoute('posts/1');

this why when you use the $this->route('post') in your form request, the result will be 1.

The package also supports substitube binding. All you need to be is to ؤreate an explicit binding and will do the work for you.

// somewhere in your app 🤔, ideally, your service provider
Route::model('post', Post::class);

when you do the reigster, the value of $this->route('post') will be a Post model rather than the id.

Alternatively

if you don't want to register a route just for the sake of resolving a route parameter then you can use FormRequestTester addRouteParameter($name, $value).

$this->formRequest(UpdatePost::class)
    ->put($data)
    ->addRouteParameter('post', 1)
    ->assertAuthorized();

according to the example above, with the new method addRouteParameter, $this->route('post') will be resolved to 1

$this->user():

This method will reteive the current authenticated user.

use laravel testing method actingAs to set a user as the current authenticated user

$user = User::factory()->create();
$this->actingAs($user);
