Hi

I have put this code in the hooks which takes scresnshot when a test fails.
The issue is that Im not getting the full browser screen. Its chops off at
the bottom

After do |scenario|
take_screenshot(@browser, scenario)
end

def take_screenshot(browser, scenario)
time = Time.now.strftime("%Y-%m-%d_%H%M")
if scenario.failed?
scenario_name = scenario.name.gsub(/[^\w\-]/, ' ')
screenshot_path = "#{scenario_name}" + "_failure_" + time
@browser.screenshot.save("./screenshots/#{screenshot_path}.png")
end
end

By the way my before hooks looks like this.

Before do|scenario|
ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
@browser.goto "https://www.sandbox.paypal.com"
@browser.cookies.clear
@browser.goto "https://portal-sandbox.afterpay.com"
@browser.cookies.clear
@browser.goto "https://i-pay.co.za"
@browser.cookies.clear
@browser.goto("ci.XXX.com/")
@browser.window.maximize
@browser.driver.manage.timeouts.implicit_wait = 0
@browser.cookies.clear
@browser.driver.manage.window.maximize
PageObject.default_element_wait=(10)
PageObject.javascript_framework = :jquery
end #before scenario

Hi Navi,

Selenium only screenshots the content in the viewport. If you want the
whole browser, you would need to take multiple screenshots.

There was a gem recently released to do this -
https://github.com/samnissen/watir-screenshot-stitch

Though I haven't tried it myself.

Hi Titus and Sam

This worked like a charm. Such a very usefull gem. Thanks a ton.
I just prepared a wiki for my project. Pasting here in case if this helps.

*For capturing full screen images*

Use gem https://github.com/samnissen/watir-screenshot-stitch
Include in Gemfile

gem 'watir-screenshot-stitch'
gem "mini_magick"
Run bundle installInstall "ImageMagick" exe on host machine

The host machine should have "ImageMagick" intsalled

The windows exe can be downloaded from
https://www.imagemagick.org/download/binaries/

Recommeneded:- ImageMagick-6.9.10-11-Q8-x64-dll
Verify Installation

Select âCommand Promptâ from the Windows Start menu. Within the window type

convert logo: logo.miff
imdisplay logo.miff

and the ImageMagick logo should be displayed in a window.
Usage

browser = Watir::Browser.new :chrome, options: {args: args}

opts = {:page_height_limit => 5000}

screenshot_path = "#{scenario_name}" + "_failure_" + time

@browser.screenshot.save_stitch(screenshot_path, browser, opts)

Hi Sam

Just found this warning
2018-09-21 20:32:17 WARN Watir Screenshot Stitch [DEPRECATION] Passing the
browser is deprecated and will no longer work in version 0.7.0 /lib/watir-
screenshot-stitch.rb:31

In fact I did try using version 0.7.0 of ImageMagick, but found this issue
mentioned in this thread (issue with convert command)
--> https://stackoverflow.com/questions/38163849/imagemagick-issue-with-windows-and-convert-function

So I reverted to 6.9

But aren't we supposed to pass browser as mentioned in the previous reply?

Cheers
Navi

Hi Navi â the version there refers to Watir Screenshot Stitch. When we publish version 0.7.0, we will no longer allow you to pass the browser in. This was a hack that we needed, but thanks to the changes Titus has made to Watir, the Screenshot class now knows the browser it was created for.

Sorry that wasnât clear!

A more readable format of the error

`convert -size 1920x1957 xc:white ./screenshots/Button Function Checkout with an email address without a website account without PERKS membership hit Continue As Guest _failure_2018-09-24_1712.png` failed with error:

Hi Sam

Issue resolved. It was basically the issue with PATH variable for Jenkins
job.

"convert.exe" is also the name of a windows executable which converts FAT
filesystem to NTFS. When you do not specify the full path of an executable

the system first searches the current working directory and then searches
the path environment variable, examining each directory from left to right,
looking for an executable filename that matches the command name given.

"C:\Windows\System32" is generally present in the beginning of %PATH%
variable, causing the Windows convert utility to launch, which fails with
"Invalid Parameter" error as expected.

As a workaround, I just modified the order of PATH variable as

SET "PATH=C:\Program Files\ImageMagick-6.9.10-Q8;%PATH%;C:\Ruby24-x64\bin"

Good God!!!
