Laracasts \\ Validation \\ FormValidationException：验证失败

Question

In the 10th video of the Build Larabook from scratch Laracasts tutorial, the author runs a functional test that turns green:

where t is an alias for vendor/bin/codecept run functional in the Vagrant vm .

However, when I run the same test, it turns red:

vagrant@homestead:~/larabook$ vendor/bin/codecept run functional
Codeception PHP Testing Framework v2.0.7
Powered by PHPUnit 4.3.4 by Sebastian Bergmann.

There was 1 error:

---------
1) Failed to sign up for a larabook account in SignUpCept (/home/vagrant/larabook/tests/functional/SignUpCept.php)
Couldn't click "Sign Up":
Laracasts\Validation\FormValidationException: Validation failed

Scenario Steps:
9. I click "Sign Up"
8. I fill field "Password Confirmation:","demo"
7. I fill field "Password:","demo"
6. I fill field "Email:","john@example.com"
5. I fill field "Username:","JohnDoe"
4. I see current url equals "/register"
3. I click "Sign Up!"


FAILURES!                          
Tests: 1, Assertions: 1, Errors: 1.

Here is the content of my SignUpCept.php file:

<?php

$I = new FunctionalTester($scenario);
$I->am('a guest');
$I->wantTo('sign up for a Larabook account');

$I->amOnPage('/');
$I->click('Sign Up!');
$I->seeCurrentUrlEquals('/register');

$I->fillField('Username:', "JohnDoe");
$I->fillField('Email:', "john@example.com");
$I->fillField('Password:', "demo");
$I->fillField('Password Confirmation:', "demo");
$I->click('Sign Up');

$I->seeCurrentUrlEquals('');
$I->see('Welcome to Larabook!');
$I->seeRecord('users', [
    'username' => 'JohnDoe',
    'email' => 'john@example.com'
]);

$I->assertTrue(Auth::check());

I must be missing something, but I cannot figure out what.

Any idea?

Answer 1

The problem was coming from the fact that the test was using the same data (username, email and password) as a user that was already in the database.

Since the validation checks the uniqueness of each new user, the test was failing.

I just removed the existing user from the database and the test passed.
