c# - 使用基类在多个浏览器中运行 Selenium 测试

Question

假设我有代码:

namespace SeleniumTests 
{
    [TestFixture(typeof(FirefoxDriver))]
    [TestFixture(typeof(InternetExplorerDriver))]
    public class TestWithMultipleBrowsers<TWebDriver> where TWebDriver : IWebDriver, new()
    {
        private IWebDriver driver;

        [SetUp]
        public void CreateDriver () {
            this.driver = new TWebDriver();
        }

        [Test]
        public void GoogleTest() {
            driver.Navigate().GoToUrl("http://www.google.com/");
            IWebElement query = driver.FindElement(By.Name("q"));
            query.SendKeys("Bread" + Keys.Enter);

            Thread.Sleep(2000);

            Assert.AreEqual("bread - Google Search", driver.Title);
            driver.Quit();
        }
    }
}

我要 block

    [SetUp]
    public void CreateDriver () {
        this.driver = new TWebDriver();
    }

移至基类。但是我不知道在这种情况下如何继承自基类。我如何处理 <TWebDriver> where TWebDriver: IWebDriver, new () ？

Answer 1

这不像您的示例那样使用泛型，而是像依赖注入(inject)一样工作。

您需要一种方法来创建网络驱动程序的实例。

public class DriverFactory
{
    public IWebDriver Driver { get; set; }

    public enum DriverType
    {
        IE,
        Firefox,
        Chrome
    }

    public IWebDriver GetDriver(DriverType typeOfDriver)
    {
        if (typeOfDriver == DriverType.IE) return new InternetExplorerDriver();
        if (typeOfDriver == DriverType.Chrome) return new ChromeDriver();
        return new FirefoxDriver(); // return firefox by default
    }
}

然后从您的设置中调用:

[Setup]
public void CreateDriver()
{
    var driverFactory = new DriverFactory();
    this.driver = driverFactory.GetDriver(DriverType.Chrome);
}

可以继承类:

public class TestWithMultipleBrowsers : DriverFactory
