具有多个步骤文件会打开多个浏览器 [英] Having Multiple Step Files Opens Multiple Browsers

问题描述

如果我有多个步骤"文件，则在执行测试时，无论我运行哪个测试，似乎正在为每个创建WebDriver.

If I have more than one Steps file, when I execute tests it seems that the WebDriver creation for each is being happening regardless of which test(s) I run.

每次运行测试时，我都会看到一个看似随机的Chrome浏览器打开.为了查看SpecFlow和ChromeDriver之间是否存在某种不兼容(我知道这是一个很长的路要走)，我将用于搜索测试的WebDriver更改为Firefox，而将要用于登录测试的WebDriver更改为Chrome.不管我运行了什么测试，我总是看到两个浏览器都打开了.一台Chrome浏览器和一台Firefox.

I was seeing a seemingly random Chrome Browser open up whenever I ran my tests. In an attempt to see if there was some sort of incompatibility between SpecFlow and ChromeDriver (a long shot, I know), I changed the WebDriver for my search tests to Firefox and left the WebDriver for my login tests as Chrome. No matter what test(s) I ran, I always saw 2 browsers open; one Chrome and one Firefox.

当我将所有步骤从SearchTestSteps.cs文件移至LoginTestSteps.cs文件时，问题消失了.

When I moved all of the steps from my SearchTestSteps.cs file into the LoginTestSteps.cs file, the problem disappeared.

所以，是的，这解决了眼前的问题，但是将我的所有步骤都放在一个文件中并不是最佳选择.这样很快就会变得笨拙.

So, yeah, this solves the immediate issue, but it is sub-optimal to have all of my steps in a single file. That can quickly become unwieldy.

由于每组步骤都需要具有自己的WebDriver，所以我很茫然.

Since each set of steps needs to have its own WebDriver, I'm at a loss.

这可能与文件夹结构以及存储的位置有关吗?这是我的样子.

Might this have something to do with folder structure and where things are stored? Here is what mine looks like.

Root
 |-Page Object Files
      |- Page Components
      |- Pages
      |- Test Tools  
 |- Step Definitions
      |- <*Steps.cs>  
 |- TESTS
      |- BDD Tests
          |-<*.feature>
      |- *standard selenium test files*

代码:

Login.feature
Feature: Login
    In order to be able to use Laserfiche
    As a legitimate user
    I want to be able to log into the repository

@SmokeTest
Scenario: Login with correct credentials
    Given I am on the Login page 
    And I have a good username/password combination
    And I select a repository
    When I fill out the form and submit
    Then I am taken to the repo page

---------------
LoginSteps.cs (I also have a SearchTestSteps.cs that looks very similar)
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using Selenium_C_Sharp_POC.Page_Object_Files.Pages;
using Selenium_C_Sharp_POC.Page_Object_Files.Test_Tools;
using TechTalk.SpecFlow;

namespace Selenium_C_Sharp_POC.StepDefinitions
{
    [Binding]
    public class LoginSteps
    {
        private static readonly IWebDriver Driver = new ChromeDriver();

        private static LoginPage _loginPage;
        private static string _username;
        private static string _password;
        private static string _repo;

        [AfterTestRun]
        public static void ShutDown()
        {
            Driver?.Close();
        }

        [Given(@"I am on the Login page")]
        public void GivenIAmOnTheLoginPage()
        {
            _loginPage = new LoginPage(Driver);
        }

        [Given(@"I have a good username/password combination")]
        public void GivenIHaveAGoodUsernamePasswordCombination()
        {
            _username = Nomenclature.WebClientPersonalUsername;
            _password = Nomenclature.WebClientPersonalPassword;
        }
        [Given(@"I select a repository")]
        public void GivenISelectARepository()
        {
            _repo = Nomenclature.RepoUnderTest;
        }

        [When(@"I fill out the form and submit")]
        public void WhenIFillOutTheFormAndSubmit()
        {
            _loginPage.Login(
                username: _username, 
                password: _password, 
                repo: _repo);
        }

        [Then(@"I am taken to the repo page")]
        public void ThenIAmTakenToTheRepoPage()
        {
            Assert.AreEqual(
                expected: _repo,
                actual: Driver.Title);

            HelperMethods.Logout(Driver);
        }
    }
}

推荐答案

我想出了如何使用绑定范围"解决此问题的方法.

I figured out how to fix this issue using Binding Scopes.

在每个步骤"文件中，我可以执行以下操作:

In each of the Steps files, I can do the following:

  [BeforeFeature(), Scope(Feature = "SearchTests")]
  public static void Startup()
  {
      _driver = new ChromeDriver();
  }

  [AfterFeature()]
  public static void ShutDown()
  {
      _driver?.Close();
  }

执行此操作将仅为我想要的测试文件打开和关闭驱动程序. 如果需要更详细的说明，我还可以选择在每次测试之前将范围限定在标签上.

Doing this opens and closes the Driver for only the Test file that I want it to. I can also choose to scope to the tag before each test if I need to get more granular.
