将重复的VCR.use_cassette场景减少到常见主题

Question

在rspec测试中使用VCR，一切正常。但我想提高代码质量，因为我在测试中多次使用相同的代码VCR.use_cassette。

以下是测试：-

context 'when request authenticated and Params are valid' do
it 'results should have success' do
VCR.use_cassette('test_service') do
post '/rates', headers: auth_headers, params: params
expect(response.status).to be(200)
end
end
it 'results should have nominal nominal_interest_rate' do
VCR.use_cassette('test_service') do
post '/rates', headers: auth_headers, params: params
expect(response.body).to include('rate')
expect(JSON.parse(response.body).class).to eq(Hash)
end
end
it 'results should have nominal discount' do
VCR.use_cassette('test_service') do
post '/rates', headers: auth_headers, params: params
expect(response.body).to include('discount')
end
end
end

在上面的代码中，我已经多次使用VCR.use_cassette。我想把它作为一个公共块，并在需要的时候多次使用。我该怎么做？

Answer 1

根据您可以使用的单据"RSpec元数据"；并将盒式磁带作为自变量({vcr: 'cassette name'}(传递给示例或示例组，例如

"spec/spec_helper.rb"；

VCR.configure do |c| 
c.configure_rspec_metadata!
end

然后

"spec/your_spec.rb">

context 'when request authenticated and Params are valid', vcr: 'test_service' do
before(:each) do 
post '/rates', headers: auth_headers, params: params
end
it 'results should have success' do
expect(response.status).to be(200)
end
it 'results should have nominal nominal_interest_rate' do
expect(response.body).to include('rate')
expect(JSON.parse(response.body).class).to eq(Hash)
end
it 'results should have nominal discount' do
expect(response.body).to include('discount')
end
end
