實例變量在黃瓜步驟中不可用

Question

嗨，我在Rails項目上工作，我必須在Cucumber上測試API。 我有一些實例變量來存儲URL，令牌等。我的第一種情況可以正常工作，但是第二種情況由於實例變量的值為nil而失敗。

功能文件：

Feature: Bill Reminder

  Scenario: Validate POST bill_reminder API with valid parameters
    When I make POST bill_reminder API call
    Then It should return success for bill_reminder

  Scenario: Validate GET bill_reminder API with valid login token
    when I send a GET request to bill reminder details
    Then the json response should have title bill reminder

步驟文件：

When(/^I make POST bill_reminder API call$/) do
  @url = 'http://example.com/api/bill_reminders'
  @params = {
              data: {
                type: "bill-reminders",
                attributes: {
                  title: "bill reminder",
                  all_day: "0",
                  start_date: "1409175049",
                  end_date: "1409175049"
                }
              }
            }
  @login_token = 'nev4hPOqyVCXGnOXLYPUhQ'
  @user_id = 402
end

Then(/^It should return success for bill_reminder$/) do
  header 'login_token', @login_token
  header 'user-id', @user_id
  response = post @url, @params

  response_body = JSON response.body
  @id = response_body['data']['id']
  expect(response.status).to eq(200)
end

When(/^I send a GET request to bill reminder details$/) do
  @url = "http://example.com/api/bill_reminders/#{@id}"
  @user_id = 402
  @login_token = 'nev4hPOqyVCXGnOXLYPUhQ'
end

Then(/^the json response should have title bill reminder$/) do
  header 'login_token', @login_token
  header 'user-id', @user_id

  response = get @url
  expect(response.status).to eq(200)
end

在這里，由於實例變量的值為nil，我的第二種情況“ json響應應具有標題提示提醒”失敗。 我不知道為什么在第二種情況下實例變量的值為nil。 請幫助我修復它。

在第二次當步驟認定中你錯過下划線_的方法。

When(/^I send a GET request to bill_reminder details$/) do
  @url = "http://example.com/api/bill_reminders/#{@id}"
  @user_id = 402
  @login_token = 'nev4hPOqyVCXGnOXLYPUhQ'
end
