难以调试 RSepec

Question

我正在尝试调试 RSpec 中的功能规范。但我无法获得例外。如果我在 auth.save! 之前放置 binding.pry，我就可以闯入。然后我检查 auth.valid? 是否为真，并且 returns 为真。我还手动调用 auth.save，没有抛出异常。但是如果我在 user.update_for_omniauth omniauth 之后放一个撬子，它就不会被击中。 update_from_omniauth 方法实际上并没有被调用，因为我正在对它进行存根。我的方法末尾有一个救援块。在那里放置撬棒也不会触发任何东西。我的规范失败了，因为我在数据库中找不到身份验证和用户。

您的测试失败的最可能原因是 click_link 触发的操作不能保证在 click_link returns 时完成。您可以通过在 click_link 之后添加几秒钟 sleep 来测试它。如果这解决了您的测试问题，那么您将希望用页面上的视觉变化替换 sleep。

click_link 'Login via Facebook'
expect(page).to have_text('You have logged in!') # expectation for whatever happens on the page after a successful login
expect ...  # rest of your test.

注意：Mocking/Stubbing 功能测试中用户的方法通常不是一个好主意（在功能测试中模拟除外部服务之外的任何东西通常是一种糟糕的代码味道），从功能测试直接访问数据库也是如此.功能测试旨在测试用户在网站上的体验，而不是直接测试实施细节。
