ruby-on-rails - 实例变量在黄瓜步骤中不可用

Question

嗨，我正在研究 Rails 项目，我必须用 Cucumber 测试 API。我有一些实例变量来存储 URL、令牌等。我的第一个场景工作正常，但我的第二个场景由于实例变量的 nil 值而失败。

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

步骤文件：

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

这里我的第二个场景“json 响应应该有标题账单提醒”由于实例变量的 nil 值而失败。我不知道为什么在第二种情况下实例变量的值为零。请帮我修复它。

在第二步定义中，您错过了方法中的下划线 _ 。

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
