Context

In a Unit test, I want to send data to a FormRequest in a REST call. I am testing the behavior of the validation rules I've written in the rules method of the FormRequest.

Sources

Unit test

    public function test_detach_user_job_status()
    {
        $response = $this->put(route('users.update', ['user' => $this->applier['id']], [
            'job' => [
            ]
        ]));
        $response->assertStatus(200);
    }

FormRequest's rules method

    public function rules()
    {
        return [
            'name' => 'nullable|string',

            'job' => 'nullable|array:id,attach_or_detach,message|required_array_keys:id,attach_or_detach',
            'job.id' => 'integer|gt:0',
            'job.attach_or_detach' => 'boolean',
            'job.message' => 'required_if:job.attach_or_detach,true|string',
        ];
    }

Behaviors

Actual behavior

The test succeeds.

Expected behavior

The test fails. Indeed, the array job is provided but no keys id or attach_or_detach or (eventually) message are provided, whereas the validation rules do specify: required_array_keys:id,attach_or_detach.

Also, if no job array is specified at all, then the validator must not reject the request because this array is not provided, nor its keys: it's perfectly normal since the array must be optional (it is nullable to provide this feature).

Question

Why doesn't Laravel make my test fail since my nullable (= optional) array is provided, and that its keys are required?

CodePudding user response：

You didn't put the correct input. you should put the post body to put() method instead of route() method

change this:

    $response = $this->put(route('users.update', ['user' => $this->applier['id']], [
        'job' => [
        ]
    ]));

to:

    $response = $this->put(route('users.update', ['user' => $this->applier['id']]),
        [
            'job' => []
        ]);
