1.截图类:
public class ScreenShot {
public WebDriver driver;
public ScreenShot(WebDriver driver) {
this.driver = driver;
}
private void takeScreenshot(String screenPath) {
try {
File scrFile = ((TakesScreenshot) driver)
.getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File(screenPath));
} catch (IOException e) {
System.out.println("Screen shot error: " + screenPath);
}
}
public void takeScreenshot() {
String screenName = String.valueOf(new Date().getTime()) + ".jpg";
File dir = new File("test-output/snapshot");
if (!dir.exists())
dir.mkdirs();
String screenPath = dir.getAbsolutePath() + "/" + screenName;
this.takeScreenshot(screenPath);
}
}
2.我们可以用testng的一个监听器来监听错误时截图:
public class DotTestListener extends TestListenerAdapter {
@Override
public void onTestFailure(ITestResult tr) {
}
}
3.也是说我们只需要在onTestFailure方法里面调用ScreenShot类里面的takeScreenshot方法即可,但是我们注意到ScreenShot类里需要传一个driver进去。
现在问题来了,对于driver的处理,各式各样,有的用到了单子模式,即把driver当成一个全局的静态变量,在哪都可以用,所以ScreenShot类里可以访问得到driver对象,但这样也有一个问题,即全局只有一个driver,如果想多线程运行时,启多个driver实例时,用这种方式做不到了,于是出现了另外一种处理方式,即每一个类或者每一个测试方法是,启一个新的driver对象,这样,driver对象不是全局的了,是类对象属性了,比如:
public class TestBase {
public WebDriver driver;
public WebDriver getDriver() {
return driver;
}
@BeforeClass
public void setUp(){
driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.navigate().to("http://www.baidu.com");
}
@AfterClass
public void tearDown(){
driver.close();
driver.quit();
}
}
public class Test10 extends TestBase{
@Test
public void testInput(){
System.out.println(5/0);
}
}
