rspec - 如何让 rspec 向我显示完整的故障跟踪

Question

当我使用厨房验证运行以下失败测试时

describe command ('cat example.txt') do
    its(:stdout) { should contain('param1 50') }
    its(:stdout) { should contain('param2 77') }
end

我得到以下失败跟踪：

Command "cat example.txt"
    stdout
        should contain "param1 50"
    stdout 
        should contain "param2 77" (FAILED - 1)

Failures:

    1) Command "cat example.txt" stdout should contain "param2 77"
       On host `101.10.5.103'
       Failure/Error: its(:stdout) { should contain('param2 77') }
           expected "This is the 1st line of my file example.txt...This is the 25th and last line of my file." to contain "param2 77"

如何让 rspec 向我显示我的文件 example.txt 的全部内容，而不仅仅是文件的第一行和最后一行以“...”分隔，就像它目前所做的那样？

使用match，如果测试失败，您可以看到实际的字符串：

describe file('example.txt') do
  its(:content) { should match /param1 50/ }
end
