如何连接到一个已经打开的浏览器？ [英] How to connect to an already open browser?

问题描述

我真的很感激如何连接到通过C＃中使用硒的webdriver一个已经打开的浏览器的指南。

I would really appreciate a guide on how to connect to an already open browser using Selenium Webdriver via C#.

这问题吃大约30％的我的脚本开发时间！

推荐答案

您可以指定开始和[TestFixtureSetUp]关闭浏览器和[TestFixtureTearDown]和[设置]中删除它和[拆除]。在[可是TestFixture]所有的测试将在同一浏览器中运行。所以，如果你有例如10个班，每个人有5个测试，而不是50浏览器的开启和关闭，将只有10。

You can specify starting and closing browser in [TestFixtureSetUp] and [TestFixtureTearDown] and remove it from [SetUp] and [TearDown]. All the tests in [TestFixture] will be run in the same browser. So if you have for example 10 classes and each of them contains 5 tests, instead of 50 browser's openings and closings there will be only 10.

    public IWebDriver driver { get; private set; };

    [TestFixtureSetUp]
    public void TestFixtureSetup()
    {
        driver = new FirefoxDriver();
        driver.Navigate().GoToUrl("http://www.google.com/");
    }

    [TestFixtureTearDown]
    public void TestFixtureTearDown()
    {
         driver.Quit();
    }

如果您要打开，一旦关闭浏览器，你可以继承[TestFixtureSetUp ]和[TestFixtureTearDown]从基类的方法，如果您有其他（A_test）前执行一个测试类将最后一个（Z_test）执行一个你可以设置和取消一些标志，这将告诉我们是否应该启动浏览器或不

If you want to open and close your browser once, you can inherit [TestFixtureSetUp] and [TestFixtureTearDown] methods from base class and if you have one test class that is executed before others (A_test) and one that is executed last (Z_test) you can set and unset some flags that will tell if we should start browser or not:

namespace Tests
{
[TestFixture]
public abstract class Test
{
    private static bool _flagSetUp;
    private static bool _flagTearDown;
    public IWebDriver driver { get; private set; };

    protected Test()
    {
    }

    public static void SetFlag(bool flagSetUp, bool flagTearDown)
    {
        _flagSetUp = flagSetUp;
        _flagTearDown = flagTearDown;
    }

    [TestFixtureSetUp]
    public void TestFixtureSetup()
    {
        if(_flagSetUp)
        {
            driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://www.google.com/");
            _flagSetUp = false;
        }
    }

    [TestFixtureTearDown]
    public void TestFixtureTearDown()
    {
        if(_flagTearDown)
        {
            driver.Quit();
        }
    }
}

namespace Tests
{
[TestFixture(new object[] { true, false })]
public class A_Test : Test
{
    public A_Test(bool flagSetUp, bool flagTearDown)
    {
        SetFlag(flagSetUp, flagTearDown);
    }

    [Test]
    public void Test1()
    {
       ...
    }
}

namespace Tests
{
[TestFixture(new object[] { false, true })]
public class Z_Test : Test
{
    public A_Test(bool flagSetUp, bool flagTearDown)
    {
        SetFlag(flagSetUp, flagTearDown);
    }

    [Test]
    public void Test2()
    {
       ...
    }
}

最后的解决方法看起来不是很好的解决方案。我们虽然第一个解决方法也并不能保证100％的测试隔离（顺便说一句，不要忘记写 driver.Navigate（）GoToUrl（http://www.google.com/）; 作为每个试验的第一工序）。所以，可能是最好的解决方法是将并行执行和设置，为每个测试拆解方法。

The last workaround looks like not good solution. Althouth first workaround also doesn't guarantee 100% tests isolation (btw don't forget to write driver.Navigate().GoToUrl("http://www.google.com/"); as first step for each test). So probably the best solution will be parallel execution and Setup, Teardown methods for each test.
