C# 如何在类之间传递对活动驱动程序的引用

我的问题是，当firstname假设由FetchName方法中的驱动程序设置时，我会收到一条错误消息，表明驱动程序为null。我能否以某种方式传递活动驱动程序实例，以便继续获取数据

[TestFixture]
public class TestBase
{
    protected IWebDriver driverChrome;

    [SetUp]
    public void Setup()
    {
        driverChrome = new ChromeDriver();
    }


    [TearDown]
    public void CleanSite()
    {
        driverChrome.Quit();
    }

}

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

类“Tests”，我在其中创建所有[test]方法

public void tests: Testbase
{
        [Test]
        public void testmethods()
        {
            string blabla = driverChrome.FindElement(By.id("dsd")).Text;
            Reuse.FetchName(out string firstname, out string lastname);
            Assert.isTrue(firstname.equals(lastname));
        } 
}

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

一个类“重用”，其中我有[test]方法将多次使用的方法

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

重用

类不是测试用例。将属性

[Test]

添加到方法时，该方法应包含断言。因此，

重用

不应该继承自

Testbase

如果您想要一个包含多个动作的类，它应该是静态类

WebDriver是一个独立的进程。您可以使用多个类或多个进程来访问它。他们都将获得相同的WebDriver

下面的示例显示了如何更改

重用

类以及如何使用它

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

public static class Reuse
{
    public static IWebDriver driverChrome;
    public static void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

你可以这样称呼它

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}

public void tests: Testbase
{
    [Test]
    public void testmethods()
    {
        string blabla = driverChrome.FindElement(By.id("dsd")).Text;
        Reuse.driverChrome = driverChrome;
        Reuse.FetchName(out string firstname, out string lastname);
        Assert.isTrue(firstname.equals(lastname));
    } 

---

}

可以将driverChrome设置为全局变量，也可以编写getter setter来获取驱动程序实例。

public class Reuse: Testbase
{
    [Test]
    public void FetchName(out string firstname, out string lastname)
    {
            firstname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text;
            lastname = driverChrome.FindElement(By.XPath("/html/body/div[2]/table/tbody[last()]/tr/td[2]/div")).Text; 
    }
}
