How to convert HTML Report to picture format in Email? So that we can see the automation report also at home or on mobile phone anywhere.

We tried to use phantomJs to get the full-page screenshot of HTML, it doesn't work well on some computers, then we found that the newest Chrome doesn't support it anymore, and Chrome has use its Headless mode to replace phantomJs.

Version 1 : phantomJs

# -*- coding: utf-8 -*-
import time
import os

from selenium import webdriver 
jenkinsJobName=os.getenv("JOB_NAME")
url="http://10.2.3.3/testAgent/AutoAnaylsisReport.html"
print url
save_fn="buildNumResult.PNG"
driver = webdriver.PhantomJS()
driver.maximize_window()
driver.get(url) # Load page
time.sleep(30) 
driver.save_screenshot(save_fn)
driver.close()
time.sleep(5) 
os.system("taskkill /F /IM phantomjs.exe")

Version 2: Chrome Headless

# -*- coding: utf-8 -*-
import time
import os

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


url="http://10.2.4.1/testAgent/BillingAnaylisisReport.html"
print url
save_fn="buildNumResult.PNG"

option = webdriver.ChromeOptions()
option.add_argument('--headless')
option.add_argument('--disable-gpu')
option.add_argument("--window-size=1280,1024")
option.add_argument("--hide-scrollbars")

driver = webdriver.Chrome(chrome_options=option)

driver.get(url)
print(driver.title)

scroll_width = driver.execute_script('return document.body.parentNode.scrollWidth')
scroll_height = driver.execute_script('return document.body.parentNode.scrollHeight')
driver.set_window_size(scroll_width, scroll_height)
driver.save_screenshot(save_fn)
driver.quit()
