Failed to take custom screenshot

[Sreejith Edayillam]

Hello,

We have implemented the custom screenshot Grabber in our Gauge automation but we alway get the regular screenshot. We are getting the following error for the custom screenshot failure.

Hi,

Can you please share some code to illustrate how you have implemented the custom screenshot grabber? Also, which Gauge/language plugin versions are you on?

thanks
Srikanth

[Sreejith Edayillam]

Hi Srikanth,

Thank you for responding my query.

Code:

public byte[] takeScreenshot() {
    WebDriver driver = BasePage.browser;

    Gauge.writeMessage("Failed URL: " + driver.getCurrentUrl());
    return ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
}

Gauge version: 0.8.3

Plugins
-------
html-report (3.1.0)
java (0.6.2)

Thank You,

Sreejith

Hi,

Naive question, but can you ensure that the class containing this method implements ICustomScreenshotGrabber

Thanks
Srikanth

[Sreejith Edayillam]

Hi Srikanth,

This is the class:

public class CustomScreenGrabber implements ICustomScreenshotGrabber {

Hi,

This looks like a potential issue with gauge-java. Your usage looks ok to me. Can you please raise an issue here: https://github.com/getgauge/gauge-java/issues/new ?

thanks

Hi,

On closer look, I think the culprit is this line from your stacktrace:

...

Failed to take Custom screenshot: com.gurutest.core.CustomScreenGrabber : timeout

  (Session info: chrome=57.0.2987.133)

  (Driver info: chromedriver=2.29.461585 (0be2cd95f834e9ee7c46bcc7cf405b483f5ae83b),platform=Mac OS X 10.11.6 x86_64) (WARNING: The server did not provide any stacktrace information)

Command duration or timeout: 1.01 seconds

...

I tried a sample project with a custom screengrabber, and it seems to work. Can you please try with a simpler implementation? Something like this?

import com.thoughtworks.gauge.screenshot.ICustomScreenshotGrabber;

import com.thoughtworks.gauge.Gauge;

public class CustomScreenGrabber implements ICustomScreenshotGrabber {

public byte[] takeScreenshot() {

Gauge.writeMessage("Custom Screengrabber");

System.out.println("Custom Screengrabber");

return "".getBytes();

}

}

thanks
Srikanth

Thank You Srikanth.

Reported the issue.

[Sreejith Edayillam]

Hi Srikanth,

Thank you for the information.

I tried again and  getting the screenshot. But still it capture only the visible area on webpage.

In selenium screenshot, we can get the complete page including the vertical scroll bar area (which is visible only on page scroll). Can you help to get a screenshot like that.

Thank You,

Sreejith.

Seems to be a chromedriver issue https://bugs.chromium.org/p/chromedriver/issues/detail?id=294
