如何使用cucumber测试ROR REST api

Question

嗨，我正在做一个使用ruby-2.5.1和Rails 5的ROR项目。我有一个注册请求的api如下：

{
  "data": {
    "type": "users",
    "attributes": {
      "email": "test@gmail.com",
      "password": "passwor",
      "password-confirmation" : "password"
    }
  }
}

我想在我的rails应用程序中使用cucumber测试这个registartion api。我从来没有研究过黄瓜，我尝试过的是：

我的功能文件

Feature: Registration Endpoint

  Scenario: User registration
    When I send a POST request to "/api/registrations" with the following:
      | email | test@gmail.com |
      | password   | password |
      | password_confirmation   | password |
    Then the response status should be "200"

我的steps.rb文件：

When("I send a POST request to {string} with the following:") do |string, table|
  # table is a Cucumber::MultilineArgument::DataTable
  pending # Write code here that turns the phrase above into concrete actions
end

但我不确定如何实现这些步骤。请帮帮我。提前谢谢。

我会这样做：

When(/^I send a POST request to "(.*)" with the following:$/) do |endpoint, table|
  page.driver.post(endpoint, table.rows_hash)
end

Then(/^the response status should be "(.*)"$/) do |response_code|
  expect(page.status_code).to eq(response_code.to_i)
end

在步骤定义中，您始终可以对binding.pry进行调试，并使用save_and_open_page在浏览器中显示结果。我希望它能有所帮助！
