Re: [selenium-users] Taking a screenshot is killing the browser as of late and used to work fine

Your test is running against firefox v37 with 2.45.0 of selenium.

I woule start from this and check if both these are compatible with each other before proceeding further.  There are a lot of threads regarding how to do this (Darrell G has sent some really nice elaborate replies that you can find in this forum )

Subject: [selenium-users] Taking a screenshot is killing the browser as of late and used to work fine

Recently I have been getting lots of instances where the browser dies on screenshot creation. Stack trace:

 [testng] INFO: Taking screenshot of failed test testThis

The code in question on the custom listener is:

    if (TestBase.driver != null && TestBase.driver instanceof TakesScreenshot) {
        LOGGER.log(Level.INFO, "Taking screenshot of failed test " + result.getMethod().getMethodName());
        File tempFile = ((TakesScreenshot) TestBase.driver).getScreenshotAs(OutputType.FILE);
        try {
        String fileName = String.format("temp/%s_%s.png", result.getMethod().getMethodName(), date);
        FileUtils.copyFile(tempFile, new File(fileName));
        LOGGER.log(Level.INFO, "Screenshot taken " + fileName);
        } catch (IOException e) {
        e.printStackTrace();
        }
    }

This used to work fine, but in the last month or so it crashes the browser, in this case FireFox running in remote. Driving me batty as nothing changed. Any ideas?
