应该匹配器和自定义错误消息

Question

我正在尝试使用 shoulda 匹配器进行一些基本的 rspec 测试，但我遇到了一个我之前从未在 SO 上看到过的错误。

我有一个名为 name 的唯一属性，但由于项目所需的原因，我在 config/locales/en.yml 中用我自己的消息形式覆盖了默认的“已被采用”消息，而应该没有好像很喜欢。

我收到了这个错误信息

 Failure/Error: it { should validate_uniqueness_of(:name) }

   Flavor did not properly validate that :name is case-sensitively unique.
     Given an existing Flavor whose :name is ‹"Factory Flavor Namea"›,
     after making a new Flavor and setting its :name to ‹"Factory Flavor
     Namea"› as well, the matcher expected the new Flavor to be invalid and
     to produce the validation error "has already been taken" on :name. The
     record was indeed invalid, but it produced these validation errors
     instead:

     * name: ["This flavor name is already in the system"]
     * abbreviation: ["This abbreviation is already in use"]

我在 shoulda-matchers 中是否缺少允许测试通过而不必担心错误消息的设置，或者这是模块的限制？

如果您不在匹配器上使用with_message 方法，则使用uses default message。

要使您的测试工作，您应该覆盖matcher's default message：

it { expect(subject).to validate_uniqueness_of(:name).with_message("has already been taken") }
