ruby-on-rails - rake spec 在 specs 之后运行测试

Question

当我在我的 Rails 项目中运行 rake spec 时，它会执行所有规范，然后尝试运行测试(如 rake test):

$ rake spec
ruby -S rspec ./spec/... #file list
# --> ...  normal RSpec output
Finished in 11.11 seconds
111 examples, 0 failures, 11 pending

# --> here starts the problem <--
Run options: 

# Running tests:

Finished tests in 0.000343s, 0.0000 tests/s, 0.0000 assertions/s.
0 tests, 0 assertions, 0 failures, 0 errors, 0 skips

你知道吗，为什么它会尝试运行 Test::Unit 测试，即使我没有这些测试？ (我什至没有test/目录)

编辑:当我运行其他 rake 命令时，它们完成了它们的工作，但随后以错误结束，例如:

Answer 1

任何带有 require test/unit 的文件都会启用一个 at_exit Hook ，该 Hook 会尝试运行测试。

如果从您的 rake 任务加载的任何文件执行此操作，at_exit Hook 将尝试使用您的 rake 命令的最后一部分作为要运行的测试的名称来运行测试。在 rake about 的情况下，它会搜索名为 about 的不存在的测试。

当我的 Gemfile 中有 shoulda gem 时，我遇到了问题。我通过将其包含在 Gemfile 中解决了这个问题:

gem 'test-unit', :require => "test/unit"
