java + selenium测试框架（之截屏） 版本演化四

截屏工具

public class ScreenShotUtil {
    public static void ScreenShoter(WebElement driver,String filePathName) {
        File screenShotFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(screenShotFile, new File(filePathName));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

如果想进行截屏，则在测试用例中调用即可。

在testng中自动截屏

为了能够在testng的用例结束时，设置自动截屏，或者在测试失败时截屏，可以使用org.testng.TestListenerAdapter来实现。

public class ScreenShotListener extends TestListenerAdapter {
    protected Logger logger = LoggerFactory.getLogger(getClass());
    protected ITestContext testContext = null;

     public String getTestName(ITestResult it){        
            return  it.getTestClass().getName() +"."+ it.getName()+it.getEndMillis();   
        }

    @Override
    public void onStart(ITestContext testContext) {
        this.testContext = testContext;
        super.onStart(testContext);
    }

    @Override
    public void onFinish(ITestContext testContext) {
        this.testContext = null;
        super.onFinish(testContext);
    }

    @Override
    public void onTestSuccess(ITestResult tr) {
        logger.info("TestSuccess:" + getTestName(tr));
        String path = ConfigurationSettings.SCREENSHOT_SUCESS_PATH + "/" + getTestName(tr)+".png";
        WebDriver driver = (WebDriver) testContext.getAttribute(ConfigurationSettings.SELENIUM_DRIVER);
        ScreenShotUtil.ScreenShoter(driver, path);
        super.onTestSuccess(tr);
    }

    @Override
    public void onTestFailure(ITestResult tr) {
        logger.info("TestFailure:"+ getTestName(tr));
        String path = ConfigurationSettings.SCREENSHOT_ERROR_PATH + "/" + getTestName(tr)+".png";
        WebDriver driver = (WebDriver) testContext.getAttribute(ConfigurationSettings.SELENIUM_DRIVER);
        ScreenShotUtil.ScreenShoter(driver, path);
        super.onTestFailure(tr);
    }

}

这时，需要在TestBase中，增加testContext:

protected ITestContext testContext = null;

@BeforeClass(alwaysRun = true)
public void setUpTestBase(ITestContext testContext) {
    try{
        driver = DriverFactory.getInstance().getDriver();
        this.testContext = testContext;
        testContext.setAttribute(ConfigurationSettings.SELENIUM_DRIVER, driver);
     } catch(Exception e ) {
         quitDriver();
         Assert.fail("SetUp failed.", e);
     }
}

在测试用例中，增加监听器注解：

@Listeners({ScreenShotListener.class})
public class BaseTestWithListener extends TestBase {

    BaiduMainPage page = null;

    @BeforeMethod
    public void initPage() {
        String path = "http://www.baidu.com/";
        page = new BaiduMainPage(driver);
        page.openAndWait(path);
        PageFactory.initElements(driver, page);
    }

    @Test
    public void testSearch(){
        String text="apple";
        page.SearchText(text);
        sleep(1);
        System.out.println(driver.getTitle());
        Assert.assertTrue(driver.getTitle().contains(text));
        System.out.println(page.getCurrentUrl());
    }   
}

当然，为了让截屏的路径可配置，需要修改properties配置文件和ConfigurationSetting：

selenium-vars.properties

#screenshot path if error occur
screenshot.error.path=error-screenshot

#screenshot path if success
screenshot.auto.path=auto-screenshot

ConfigurationSettings.java

public final static String SELENIUM_DRIVER="SELENIUM_DRIVER";

public static final String SCREENSHOT_ERROR_PATH = getProperty("screenshot.error.path").trim();

public static final String SCREENSHOT_SUCESS_PATH = getProperty("screenshot.auto.path").trim();
