在使用JAVA和Cucumber进行测试的每个步骤之后，如何捕获屏幕截图？

在运行集成测试时，捕获屏幕截图的最佳方法是什么？

使用Selenium（3.0.1）和Cucumber（1.2.4）用Java编写测试。

下面是用于在测试后获取屏幕截图的代码，但是在每种方法后面都标有@ Given，@ When，@ Then时，我需要屏幕截图。

@After
public void after(Scenario scenario){
    final byte[] screenshot = driver.getScreenshotAs(OutputType.BYTES);
    scenario.embed(screenshot, "image/png");
}

谢谢您的任何提示。

使用方面解决了这个问题。非常棘手，请注意注释：

@After("call(public * cucumber.runtime.StepDefinitionMatch.runStep(..)) && within(cucumber.runtime.Runtime)")
