Laravel 5.7: Phpunit error - call to a member function getBag() on a string

Question

I'm testing saving data into the database. When missing required fields I throw an exception and then redirect from my controller:

try {
            $product = Product::create([
                'name' => $request->name,
                'description' => $request->description,
            ]);

            return redirect('home')->with('success', 'Record has been added');

        } catch(\Exception $e) {

            return redirect()->to('course/create')
                    ->withInput($request->input())
                    ->with('errors', 'Required Fields Not Submitted');
        }

I wanna test the redirect, whether the session has errors and whether the initial data passed is returned in order to populate the form, so in my unit test I have:

$response = $this->post("/courses/", $data);

$response->assertRedirect('/courses/create');
$response->assertSessionHasErrors();
//$response->assertSessionHasAll();
$response->assertHasOldInput();

but when hitting assertSessionHasErrors I'm getting:

Error: Call to a member function getBag() on string

and when hitting assertHasOldInput I'm getting:

BadMethodCallException: Call to undefined method Illuminate\Http\RedirectResponse::assertHasOldInput()

what seems to be the issue?

Thanks.

Do this instead:

$response = $this->call('POST',  "/courses/", $data);

$response->assertRedirect('/courses/create');
$response->assertSessionHasErrors();
$response->assertHasOldInput();

You cannot do that I believe, the redirect comes from the response, so when changed to $this it'll say undefined method assertRedirect() – MrCujo Sep 14 '18 at 05:21
let's debug... Do a `dd($response)`... What do you see? – Chukwuemeka Inya Sep 14 '18 at 05:43

I think you should use call method instead of post

Docs - Calling Routes From Tests

Try this

$response = $this->call("POST", "/courses/", $data);
$response = $this->assertRedirect('/courses/create');
$response = $this->assertSessionHasErrors();
$response = $this->assertHasOldInput();

Nope, the errors are still present and they are the same as before – MrCujo Sep 14 '18 at 05:20
