java - JUnit测试失败钩子上的黄瓜 [英] java - Cucumber on JUnit Test Failure Hook

问题描述

我们使用Cucumber-JVM编写验收测试脚本，使用JUnit执行它们（通过JUnit Cucumber运行器）。由于这些测试涉及Selenium WebDriver，我希望能够在我的测试失败时获取屏幕截图（我有代码）。

We use Cucumber-JVM to script our acceptance tests and JUnit to execute them (via the JUnit Cucumber runner). As these tests involve Selenium WebDriver, I want to be able to take a screenshot should my test fail (which I have the code for).

如果我只是添加一个WebDriver onException hook，断言失败时不会截取屏幕截图。我希望能够向Cucumber运行器添加JUnit执行侦听器，但API似乎不支持此功能（在Cucumber.class上没有addListener方法）。

If I simply add a WebDriver onException hook, the screenshot won't be taken when an assertion fails. I want to be able to add a JUnit execution listener to the Cucumber runner, but the API doesn't seem to support this (no addListener method on Cucumber.class).

有人可以帮忙吗？谢谢团队。

Can anyone help? Thanks team.

推荐答案

我一般在 @After 钩子中截取屏幕截图在每个黄瓜情景之后被调用。 @After hook方法需要一个特殊的 Scenario 对象，以便您可以在报告中嵌入屏幕截图。下面是一个关于如何在场景失败时拍摄截图的示例，

I generally take screenshots in the @After hook which gets called after every cucumber scenario. @After hook method takes a special Scenario object so that you can embed your screenshots in your reports. Here is an example on how to take screenshots in the event your scenario fails,

   @After
    public void tearDown(Scenario scenario) {
        try {
            if (scenario.isFailed()) {
                final byte[] screenshot = ((TakesScreenshot) driver)
                        .getScreenshotAs(OutputType.BYTES);
                scenario.embed(screenshot, "image/png");
            }
        } finally {
            driver.quit();
        }
    }
