Laravel - HTTP Tests - Assert Valid

Assert that the response has no validation errors for the given keys. This method may be used for asserting against responses where the validation errors are returned as a JSON structure or where the validation errors have been flashed to the session:

    
    // Assert that no validation errors are present...
    $response->assertValid();
    
    // Assert that the given keys do not have validation errors...
    $response->assertValid(['name', 'email']);
