c# - Selenium 测试运行后 GhostDriver 没有退出

Question

在我使用 GhostDriver (PhantomJS) 对 Selenium 进行的第一个非常简单的测试中，测试通过了，但 PhantomJS.exe 没有退出。我在 Windows 7、PhantomJS 1.9.0、Selenium WebDriver API 2.32.1 和 NUnit 2.6.2.12296、.NET 3.5 上运行。

这是我的 C#/Nunit/WebDriver 代码:

[TestFixture]
public class Driver
{
    IWebDriver driver;

    [SetUp]
    public void Setup()
    {
        driver = new PhantomJSDriver(@"D:\src\Tests\Drivers");
    }

    [TearDown]
    public void Teardown()
    {
        driver.Quit();
        driver.Dispose();
    }

    [Test]
    public void GoogleSearch()
    {
        //Navigate to the site
        driver.Navigate().GoToUrl("http://www.google.com");
        Assert.AreEqual("Google", driver.Title);
    }
}

这里是 PhantomJS 的所有内容:

PhantomJS is launching GhostDriver...

但它永远不会关闭...有什么想法吗？

Answer 1

[TestFixture]
public class Driver
{
    [Start]
    public void Start()
    {
       using (var driver = new PhantomJSDriver(@"D:\src\Tests\Drivers"))
       {
          driver.Url = "https://www.google.com";
          Assert.AreEqual("Google", driver.Title);
       }
    }
}

这将解决您的问题，只要始终记住在可以或显式调用 driver.Dispose(); 时将事物封装在 using 语句中，如果它是公共(public)变量，则可以将 Dispose 放在析构函数中如果您愿意，可以在类的任何部分或一些很长的行中，当类退出时，将调用解构函数并执行您的代码行。

使用语句将为您进行清理。
