我有以下rspec測試,並且我正在嘗試在其中存根API方法。我在FactoryGirl的trait中定義了stub,並在(:build)回調之後使用。Rspec stubbing在FactoryGirl的特質
describe '#get_json_from_api' do
let(:output_file) { video_file.json_path }
context "when api works" do
around(:each) do |rspec_test|
File.delete(output_file) if File.exists?(output_file)
rspec_test.run
File.delete(output_file) if File.exists?(output_file)
end
let!(:searched_video_file) {
create(:video_file, :stub_api)
video_file.get_json_from_api
video_file
}
it { expect(File.size?(output_file)).to be > 0 }
end
end
這裏的工廠:
factory :video_file do
trait :stub_api do
after(:build) do |vf|
vf.stub(:get_json_from_api){
puts "i am callled!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
File.open(vf.json_path, "w") do |f|
f.write ["some data","more data"].to_json
end
}
end
end
end
成株從未發生和RSpec測試失敗。然而,一切正常需要,如果我刪除一個特點,簡單地離開:
factory :video_file do
after(:build) do |vf|
vf.stub(:get_json_from_api){
puts "i am callled!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
File.open(vf.json_path, "w") do |f|
f.write ["some data","more data"].to_json
end
}
end
end
是的,但我需要分享它在不同型號的測試之間 –
我其實也是這麼認爲,但後來我讀了http://stackoverflow.com/questions/9072338/should-i-stub-the-model-in -factory-girl-or-the-spec-file-while-testing,並且有點決定嘗試 –
