Selenium 可以在 JUnit 测试失败时截取屏幕截图吗? [英] Can Selenium take a screenshot on test failure with JUnit?

问题描述

当我的测试用例失败时，尤其是在我们的构建服务器上，我想拍一张屏幕的图片/截图来帮助我调试后来发生的事情.我知道如何截取屏幕截图，但我希望在 JUnit 中有一种方法可以在浏览器关闭之前在测试失败时调用我的 takeScreenshot() 方法.

When my test case fails, especially on our build server, I want to take a picture / screenshot of the screen to help me debug what happened later on. I know how to take a screenshot, but I was hoping for a way in JUnit to call my takeScreenshot() method if a test fails, before the browser is closed.

不，我不想编辑我们无数的测试来添加 try/catch.我想，我可能，只是可能被谈论成一个注释.我所有的测试都有一个共同的父类，但我想不出我能做些什么来解决这个问题.

No, I don't want to go edit our bazillions of tests to add a try/catch. I could maybe, just possibly be talked into an annotation, I suppose. All of my tests have a common parent class, but I can't think of anything I can do there to solve this.

想法?

推荐答案

几次快速搜索使我找到了这个:

基本上，他建议创建一个 JUnit4 Rule 将测试 Statement 包装在他调用的 try/catch 块中:

Basically, he recommends creating a JUnit4 Rule that wraps the test Statement in a try/catch block in which he calls:

imageFileOutputStream.write(
    ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES));

这对您的问题有用吗?
