我们如何执行顺序浏览器测试？

Question

资源：VS 2017，Selenium webdriver 3.8，Nunit 3.9，FF 56

使用这种方法我们怎么能顺序运行多个浏览器？我知道我们可以在Nunit中进行并行执行，但我想顺序执行。我在概念上和实用上都陷入困境。任何评论将不胜感激。

这是一个GlobalConfig.xml - 在这里给出键值对

<?xml version="1.0" encoding="utf-8" ?> 
<Automation>
  <RunSettings>
    <AppURL>https:/abcd.com/Login/Login.aspx</AppURL>
    <BrowserType>Firefox</BrowserType>
    <Username>user123</Username>
    <Password>pass123</Password>
  </RunSettings>
  </Automation>

这是setting.cs - 在这里定义属性

  namespace Automation.Config
{
    public class Settings
    {
        public static string AppURL { get; set; }
        public static string Username { get; set; }
        public static string Password { get; set; }
       public static string BrowserType { get; set; }
    }
}

这是configReader.cs - 使用XPathItem类来呈现项目

namespace Automation.Config
{
    public class ConfigReader
    {
        public static void FrameworkConfigSettings()
        {
            XPathItem appUrl;
            XPathItem username;
            XPathItem password; 
            XPathItem browserType;

            string strFilename = TestContext.CurrentContext.TestDirectory.ToString() + "\\Config\\GlobalConfig.xml";
            FileStream stream = new FileStream(strFilename, FileMode.Open);
            XPathDocument document = new XPathDocument(stream);
            XPathNavigator navigator = document.CreateNavigator();

            //Get XML Details and pass it in XPathItem type variables
            // get node content by using simple xpath expression and C#
            appUrl = navigator.SelectSingleNode("Automation/RunSettings/AppURL");
            username = navigator.SelectSingleNode("Automation/RunSettings/Username");
            password = navigator.SelectSingleNode("Automation/RunSettings/Password");
            browserType = navigator.SelectSingleNode("Automation/RunSettings/BrowserType");


            //Set XML Details in the property to be used accross framework
            Settings.AppURL = appUrl.Value.ToString();
            Settings.Username = username.Value.ToString();
            Settings.Password = password.Value.ToString();
            Settings.BrowserType = browserType.Value.ToString();

        }
    }
}

driver.cs class - 这是获取浏览器字符串名称的驱动程序类。

 public static void Initialize(string browser)
        {

            if (browser.Equals(Constant.Chrome))
            {                
                ChromeOptions options = new ChromeOptions();
                Instance = new ChromeDriver(DrivePath, options, TimeSpan.FromSeconds(100));
                Instance.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);

            }
            else if(browser.Equals(Constant.Firefox))
            {

                FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(DrivePath);
                service.FirefoxBinaryPath = DrivePath;
                var profile = new FirefoxProfile();
                profile.AcceptUntrustedCertificates = true;
                var options = new FirefoxOptions();
                options.AcceptInsecureCertificates = true;
                options.Profile = profile;
                Instance = new FirefoxDriver(service.FirefoxBinaryPath, options, TimeSpan.FromSeconds(100));
                Instance.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);           

            }

        }
