我正在执行一个 selenium-cucumber 框架，但遇到以下问题：`

org.openqa.selenium.WebDriverException: Could not convert screenshot to base64 -

            System.err.println(somePlatformsDontSupportScreenshots.getMessage());
        }

试试这个并根据你的需要修改它

    @After
public void shutDown(Scenario scenario){
    if (scenario.isFailed()) {
        final byte[] screenshot = ((TakesScreenshot) Driver.getDriver()).getScreenshotAs(OutputType.BYTES);
        scenario.embed(screenshot, "image/png");
    }
    Driver.closeDriver();

}

在截屏时尝试这个错误。它可以在 Cucumber 范围报告中添加失败测试用例的屏幕截图。

public void forAfterScen(Scenario scenario) throws IOException
    {
        if (scenario.isFailed()) {
            String screenshotName = scenario.getName().replaceAll(" ", "_");
            try {
                TakesScreenshot ts = (TakesScreenshot) driver;
                File sourcePath = ts.getScreenshotAs(OutputType.FILE);

                File destinationPath = new File(System.getProperty("user.dir") + "\\Report\\" + screenshotName+".png");

                Files.copy(sourcePath, destinationPath);   

                Reporter.addScreenCaptureFromPath(destinationPath.toString());
                Reporter.addScenarioLog(screenshotName);
            } catch (IOException e) {
            } 
        }
    }
