对于单个示例的规格文件，您需要在最后添加行号，例如

rspec spec/controllers/api/v1/card_list_controller_spec.rb:35

对于单个文件，您可以指定您的文件路径，例如

rspec spec/controllers/api/v1/card_list_controller_spec.rb

对于spec文件夹中的整个Rspec示例，您可以尝试使用此命令

bundle exec rspec spec

我使用这个守护宝石自动运行我的测试。它在对测试文件进行创建或更新操作后执行测试。

https://github.com/guard/guard-test

或 通常可以使用以下命令运行

rspec spec / controllers / groups_controller_spec rb。

从项目的根目录运行命令:

# run all specs in the project's spec folder
bundle exec rspec 

# run specs nested under a directory, like controllers
bundle exec rspec spec/controllers

# run a single test file
bundle exec rspec spec/controllers/groups_controller_spec.rb

# run a test or subset of tests within a file
# e.g., if the 'it', 'describe', or 'context' block you wish to test
# starts at line 45, run:
bundle exec rspec spec/controllers/groups_controller_spec.rb:45

此外，您可以使用——example (-e)选项来运行特定的测试，这些测试部分或完全匹配给定测试路径的'it'、'describe'或'context'块中的文本标签:

# run groups controller specs in blocks with a label containing 'spaghetti flag is false'
bundle exec rspec spec/controllers/groups_controller_spec.rb -e 'spaghetti flag is false'

# Less granularly, you can run specs for blocks containing a substring of text 
# that matches one or more block labels, like 'spaghetti' or 'paghett'
bundle exec rspec spec/controllers/groups_controller_spec.rb -e spaghetti

这将运行块内嵌套的所有测试，标签与示例选项接收到的字符串参数匹配。

When using the example option, I recommend also appending --format documentation (shorthand: -f documentation) to your bundle command (e.g., bundle exec rspec spec/some_file.rb -e spaghetti -f documentation). Documentation-formatting replaces the normal ./F output with an easy-to-read pretty printed breakdown showing the nested block labels for the examples you're running and outputs the printed label for each example (it block) in green or red to denote whether it passed or failed. This provides better confirmation that your example argument matches the specs you intended to run, and it gives live visibility to which examples are passing/failing during longer test runs where the example argument matches many block labels and/or matched blocks contain many nested examples.

例子的选择 格式选项

Rake:

rake spec SPEC=path/to/spec.rb

(这个答案值得称赞。去给他投票吧。)

编辑(感谢@cirosantilli):要在规范中运行特定场景，必须提供与描述匹配的正则表达式模式匹配。

rake spec SPEC=path/to/spec.rb \
          SPEC_OPTS="-e \"should be successful and return 3 items\""

从rspec 2开始，你可以使用以下代码:

# in spec/spec_helper.rb
RSpec.configure do |config|
  config.filter_run :focus => true
  config.run_all_when_everything_filtered = true
end

# in spec/any_spec.rb
describe "something" do
  it "does something", :focus => true do
    # ....
  end
end

我偏爱的运行特定测试的方法略有不同—— 我添加了这些行

  RSpec.configure do |config|
    config.filter_run :focus => true
    config.run_all_when_everything_filtered = true
  end

到我的spec_helper文件。

现在，每当我想要运行一个特定的测试(或上下文或规范)时，我可以简单地向它添加“focus”标签，并正常运行我的测试——只有被聚焦的测试才会运行。如果我删除所有的焦点标签，run_all_when_everything_filtered就会生效，并正常运行所有测试。

它不像命令行选项那样快速和简单——它需要您为想要运行的测试编辑文件。但我觉得这能给你更多的控制。
