Behat 3 with Laravel 5: 验收测试通过但不应该

Question

我正在使用 Behat 3 和 Mink 对 Laravel 5 应用程序进行首次验收测试。

Homestead VM 下的应用程序运行。

测试很简单，位于 features/example.feature 文件中。这是测试：

Feature: Sample

    In order to learn Behat
    As a programmer
    I need a simple url testing

    Scenario: Registration
        Given I am not logged in
        When I go to the registration form
        Then I will be automatically logged in

FeatureContext.php 有这个 class:

<?php

use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;

/**
 * Defines application features from the specific context.
 */
class FeatureContext extends MinkContext implements Context, SnippetAcceptingContext
{
    /**
     * Initializes context.
     *
     * Every scenario gets its own context instance.
     * You can also pass arbitrary arguments to the
     * context constructor through behat.yml.
     */
    public function __construct()
    {
    }

    /**
     * @Given I am not logged in
     */
    public function iAmNotLoggedIn()
    {
        Auth::guest();
    }

    /**
     * @When I go to the registration form
     */
    public function iGoToTheRegistrationForm()
    {
       $this->visit(url('my/url'));
    }

    /**
     * @Then I will be automatically logged in
     */
    public function iWillBeAutomaticallyLoggedIn()
    {
        Auth::check();
    }
}

然后，当我从命令行运行 behat 时，我预计测试会失败，因为没有 my/url 路由（routes.php 文件只有/).

的路线

但是，测试returns绿色，我看到的是这样的：

Feature: Sample

    In order to learn Behat
    As a programmer
    I need a simple url testing

  Scenario: Registration                   # features/example.feature:7
    Given I am not logged in               # FeatureContext::iAmNotLoggedIn()
    When I go to the registration form     # FeatureContext::iGoToTheRegistrationForm()
    Then I will be automatically logged in # FeatureContext::iWillBeAutomaticallyLoggedIn()

1 scenario (1 passed)
3 steps (3 passed)
0m0.45s (22.82Mb)

当然，我使用的是 laracasts/behat-laravel-extension 包，这是 beat.yml 文件的内容：

default:
    extensions:
        Laracasts\Behat: ~
        Behat\MinkExtension:
            default_session: laravel
            laravel: ~

非常感谢您的帮助！

Answer 1

行为很简单。如果在执行某个步骤时抛出异常，它将认为该步骤失败。否则将步骤视为成功。

据我从 the docs 得知，如果用户未通过身份验证，Auth::check() 不会抛出异常。它只是 returns 一个布尔值。

你的步骤应该更像下面这样实现：

    /**
     * @Then I will be automatically logged in
     */
    public function iWillBeAutomaticallyLoggedIn()
    {
        if (!Auth::check()) {
            throw new \LogicException('User was not logged in');
        }
    }

您的 "I go to the registration form" 步骤成功，因为您没有真正验证您访问的页面是否是您预期加载的页面。同样，如果您访问的页面不正确，您应该抛出异常。
