ruby - RSpec 在使用 -f 格式化程序时抛出参数错误

Question

我正在使用 ruby​​ 和 rspec 与 watir 一起编写自动化测试用例。

C:\Users\san\Dragon>gem list 'rspec'

*** LOCAL GEMS ***

rspec (3.4.0, 2.14.1)
rspec-core (3.4.3, 2.14.8)
rspec-expectations (3.4.0, 2.14.5)
rspec-mocks (3.4.1, 2.14.6)
rspec-support (3.4.1)

当我使用以下命令运行测试用例时。

C:\Users\san\Dragon>rspec -f spec\sampletest_spec.rb:65

我遇到了这个错误

同样的错误

rspec spec\sampletest_spec.rb --格式文档
rspec --format spec\sampletest_spec.rb

Answer 1

你把事情搞砸了。 --format/-f 参数期望将格式描述本身传递给它，同时传递测试文件的名称。

我不知道为什么有问题

rspec spec\sampletest_spec.rb --format documentation

这个必须工作。但无论如何，最简单的解决方案是在项目根目录中创建具有以下内容的 .rspec 文件:

--format documentation

是的，唯一的线路。创建此文件后，只需运行

rspec spec\sampletest_spec.rb

RSpec 将从该文件中读取配置并应用所需的格式。
