selenium - 测试失败后关闭浏览器

Question

我正在使用 WebDriver 运行测试，当测试失败时，浏览器不会关闭。在 Windows 机器上，这是一个大问题，因为我有几个 IEDriver 实例仍在后台运行。

我试过 try/catch 语句，但似乎也不起作用。如果测试失败，浏览器仍保持打开状态。任何帮助将不胜感激。

try catch 语句看起来像这样:

try
{
   Assert.something(something something dark side);
   driver.quit();
}
catch(Exception e)
{
   System.out.println(e)
   driver.quit();
}

我的完整代码如下:

public class ClickAddMedication 
{
Browser browser = new Browser();

public void addMedication(String driverName)
{
    //Open Browser and navigate to page
    WebDriver driver = browser.getDriver(driverName);
    driver.manage().window().maximize();
    driver.get("http://someIP:8080/hmp_patient/index.html");

    //Click Add Medication button
    WebElement addBtn = driver.findElement(By.id("add-btn"));
    addBtn.click();

    //Verify Add Medication page has loaded successfully
    WebElement rxBtn = driver.findElement(By.className("icon-rx"));
    WebElement otcBtn = driver.findElement(By.className("icon-otc"));
    WebElement herbBtn = driver.findElement(By.className("icon-herb"));

    Assert.assertEquals(true, rxBtn.isDisplayed());
    Assert.assertEquals(true, otcBtn.isDisplayed());
    Assert.assertEquals(true, herbBtn.isDisplayed());

    driver.quit();

}

@Test(groups = {"functionalTests.FF"})
public void test_AddMedication_FF()
{
    addMedication("firefox"); 
}
@Test(groups = {"functionalTests.iOS"})
public void test_AddMedication_iOS()
{
    addMedication("iOS");
}
}

我使用 testng.xml 文件运行测试，并且无论测试是否通过都希望关闭浏览器。

下面是我的浏览器类:

public class Browser 
{
public WebDriver getDriver(String driverName)
{
    WebDriver driver = null;
    if(driverName == "firefox")
    {
        driver = new FirefoxDriver();
    }
    else if(driverName == "chrome")
    {
        File chromeFile = new File ("C:/webdrivers/chromedriver.exe");
        System.setProperty("webdriver.chrome.driver", chromeFile.getAbsolutePath());
        driver = new ChromeDriver();
    }
    else if(driverName == "ie")
    {
        File ieFile = new File("C:/webdrivers/IEDriverServer.exe");
        System.setProperty("webdriver.ie.driver", ieFile.getAbsolutePath());
        driver = new InternetExplorerDriver();
    }
    else if(driverName == "iOS")
    {
        try 
        {
            driver = new RemoteWebDriver(new URL("http://localhost:3001/wd/hub"), DesiredCapabilities.ipad());
        } catch (MalformedURLException e) 
        {

            e.printStackTrace();
        }
    }


    return driver;

}
}

您没有提到您正在使用什么框架来执行测试，但是处理这个问题的一种方法是使用等效于“测试后”注释的方法来完成此操作。 JUnit 将此注释称为 @After，而 TestNG 将其称为 @AfterMethod。用 after test 注释注释的方法将在每个用 @Test 注释的方法之后运行，而不管测试的通过/失败状态。如果您希望跨测试方法使用相同的驱动程序实例，大多数测试运行器都有一个 @AfterClass 注释或类似的注释，它将在所有 @Test 方法的末尾运行在类里面。

例如，您想要执行如下操作(注意将 driver 变量提升为类中的成员变量):

public class ClickAddMedication 
{
    // N.B. For this approach to work, you *must* have the "driver"
    // variable here. Having it as a member variable of the class is
    // what allows the addMedication() method to access it for manipulating
    // the browser, and the tearDown() method to access it for closing
    // the *same* *browser* *instance*.
    WebDriver driver;
    Browser browser = new Browser();

    public void addMedication(String driverName)
    {
        //Open Browser and navigate to page
        driver = browser.getDriver(driverName);
        driver.manage().window().maximize();
        driver.get("http://someIP:8080/hmp_patient/index.html");

        //Click Add Medication button
        WebElement addBtn = driver.findElement(By.id("add-btn"));
        addBtn.click();

        //Verify Add Medication page has loaded successfully
        WebElement rxBtn = driver.findElement(By.className("icon-rx"));
        WebElement otcBtn = driver.findElement(By.className("icon-otc"));
        WebElement herbBtn = driver.findElement(By.className("icon-herb"));

        Assert.assertEquals(true, rxBtn.isDisplayed());
        Assert.assertEquals(true, otcBtn.isDisplayed());
        Assert.assertEquals(true, herbBtn.isDisplayed());
    }

    @AfterMethod
    public void tearDown()
    {
        driver.quit();
    }

    @Test(groups = {"functionalTests.FF"})
    public void test_AddMedication_FF()
    {
        addMedication("firefox"); 
    }

    @Test(groups = {"functionalTests.iOS"})
    public void test_AddMedication_iOS()
    {
        addMedication("iOS");
    }
}
