How to take full screen, screenshots after test fails

[NaviHan]

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.

Thanks Justin, Let me give it a go..

Hi Navi -- I created that gem, help maintain it, and would be happy to help you if you run across any issues.

Hi Sam

Thanks for reaching out. I will try that out tomorrow from office. Will let you know the outcome :-)

Hey Sam. Is now a good time to release the update and publish a blog post about it? :)

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 install

Install "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 “Command Prompt” 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 — 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 wasn’t 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!!!
