rspec - 带参数的用户让

Question

我想测试这个类:

class Response

  def initialize(raw_response:)
     ........
  end
end

我想在 rspec 中发送多个 raw_responses。我实现了这段代码:

  let(:successful_response)    { File.read(File.join('spec', 'fixtures', 'xml', 'successful_response.xml')) }
  ......
  let(:response)               { described_class.new(raw_response: file_name) }

  context '#response' do

    it 'submits response' do 

      let(:file_name) { :successful_response }              
      expect(:response(raw_response: :file_name).parse_response).to include(................)
    end
  end

但是当我运行代码时出现这个错误:

syntax error, unexpected '(', expecting ')'
expect(:response(raw_response: :file_name).par...
                         ^

我该如何解决这个问题？

Answer 1

这是你的做法:

context 'when response is successful' do
  let(:file_name) { successful_response } 
  it 'submits response' do              
    expect(response.parse_response).to include(...)
  end
end

context 'when response is unsuccessful' do
  let(:file_name) { 'bad.xml' } 
  it 'submits response' do              
    expect(response.parse_response).to include(...)
  end
end

不要在 it/specify 中使用 let - 它不会起作用。如果您需要更改不同上下文的值 - 使用 context。

你可以把 let 想成定义一个内存方法。

let(:response) { described_class.new(raw_response: filename) }
let(:filename) { :foo }

就像

def response 
  described_class.new(raw_response: filename)
end

def filename
  :foo
end
