How to test authentication via API with Laravel Passport?

Question

I\'m trying to test the authentication with Laravel\'s Passport and there\'s no way... always received a 401 of that client is invalid, I\'ll leave you what I\'ve tried:

Answer 1

I think the selected answer is likely the most robust and best here so far, but I wanted to provide an alternative that worked for me if you just need to quickly get tests passing behind passport without a lot of setup.

Important note: I think if you're going to do a lot of this, this isn't the right way and other answers are better. But in my estimation this does seem to just work

Here's a full test case where I need to assume a user, POST to an endpoint, and use their Authorization token to make the request.

create();
        Passport::actingAs($user);

        //See Below
        $token = $user->generateToken();

        $headers = [ 'Authorization' => 'Bearer $token'];
        $payload = [
            //...
        ];



        $response = $this->json('POST', '/api/resource', $payload, $headers);

        $response->assertStatus(200)
                ->assertJson([
                    //...
                ]);

    }
}

And for clarity, here is the generateToken() method in the User model, which leverages the HasApiTokens trait.

public function generateToken() {
    return $this->createToken('my-oauth-client-name')->accessToken; 
}

This is fairly rough and ready in my opinion. For example it if you're using the RefreshDatabase trait you have to run the passport:install command like this in every method. There may be a better way to do this via global setup, but I'm fairly new to PHPUnit so this is how I'm doing it (for now).
