在 WebDriver 方法中获取 Specflow 标签

Question

我正在使用 c#、selenium 和 specflow 运行自动化测试套件。如果可能，我希望能够查看为当前场景分配了哪些标签，以便我可以为每个场景实例化特定的浏览器类型。这甚至可以使用 XUnit 吗？

登录功能文件：

Feature: Login
    In order to login to DRIVE
    As a user
    We have to enter login details

Background:
    Given I am on the login page

@headless
Scenario: Logging in as a valid user
    And I enter a valid user and password
    When I submit the login form
    Then The user should be logged in

WebDriverContext.cs 文件

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.PhantomJS;

namespace Drive.Acceptance.Tests
{
    public interface IWebDriverContext {
        IWebDriver GetDriver();
    }

    public class WebDriverContext : IWebDriverContext
    {
        private static volatile WebDriverContext _instance;
        private static readonly object Lock = new object();

        public static IWebDriverContext Instance
        {
            get
            {
                if (_instance == null)
                {
                    lock (Lock)
                    {
                        if (_instance == null)
                            _instance = new WebDriverContext();
                    }
                }

                return _instance;
            }

        }

        public IWebDriver GetDriver()
        {
            lock (Lock)
            {
                // TODO: create headless browser if scenario is tagged with @headless
                if (!TagName.Contains("headless")) {
                    return new ChromeDriver();
                }
                else {
                    return new PhantomJSDriver();
                }
            }
        }
    }
}

您可以在 ScenarioContext 中获取该场景的标签列表。

ScenarioContext.ScenarioInfo.Tags

见https://github.com/techtalk/SpecFlow/blob/master/TechTalk.SpecFlow/ScenarioInfo.cs

您可以通过 Context-Injection ( http://specflow.org/documentation/Context-Injection/ ) 或通过 ScenarioContext.Current ( http://specflow.org/documentation/ScenarioContext/ )获取实际的 ScenarioContext 。
如果可能的话，通过 Context-Injection 获得它。这样，如果您想并行运行测试，将来就不会遇到问题。
