Laravel 5.2 PHPUnit JSON Api请求正文未设置

Question

I am testing POSTing data to an API endpoint we've created using Laravel 5.2, but none of the parameters seem to be reaching the application in the test. The endpoint expects json and responds with json and uses a FormRequestValidator which has required rules for active and make parameters. The test fails with status code 422 and the examining the response body it states the active and make parameters are required even though they are being passed in the call so therefore for some reason when the request reaches the the Form Request Validator, the input is not there.

However, when I invoke the endpoint with json body including make and active from Postman or the UI app we've built it works fine, it is only failing in the PHPUnit tests therefore it must be something with PHPUnit or the test setup being incorrect. Here is the test:

public function testItStoresCars()
{
    // Arrange
    $user = User::first();

    //Act
    $this->json(Request::METHOD_POST, '/v1/cars', [
        'active' => true,
        'make' => 'Audi'
    ], 
    ['Authorization' => 'Bearer '.\JWT::fromUser($user)]));

    // Assert
    $this->assertResponseOk();
}

I know the Authorisation header is set correctly from other tests passing.

I've tried disabling middleware, using the $this->post helper method and manually setting the headers as well as using the $this->call method with setting the Headers and encoding the data using json_encode but I always get the same 422 response. I'm wondering has anyone encountered this issue or can see an error?

Controller Code

public function store(CreateCarRequest $request)
{
    $car = $this->carRepo->save($request->all());

    return response()->json(car);
}

FormRequest

class CreateCarRequest extends Request
{
public function rules()
{
    return [
        'active' => 'required|boolean',
        'make' => 'required',
    ];
}
}

422 is the error response for validation errors.. which means either your data is not posted or it doesn't pass server validation, try

$this->json(Request::METHOD_POST, '/v1/cars', [
        'active' => true,
        'make' => 'Audi'
    ], 
    ['Authorization' => 'Bearer '.\JWT::fromUser($user)]))->dump();

dump() should show you the errors
