Background

I You’re a BOFH at GlobalFskcup Ltd.

I Everyday you deal with numerous incidends.

I You have to seek approval and/or log every change made.

I The Head of IT has his favorite tool for that

I MacroHard PointShare form

I Rich editor filled form, with sparkling format choosers.

I Bells and whistles included

The soft problem

I Filling the form takes 5-20 minutes each time

I No PFY available to do the job

I Keeping templates in a text document... sooooo 1990

I Browser plugins - does not recognize all of provided inputs

I curl - yeah right, like I have time for that

Selenium - basics

1 from selenium import webdriver

2 driver = webdriver.Firefox ()

3 driver.get("http :// google.com")

4 driver.find_element_by_id("...")

how to identify element → inspect element

Selenium - interact with webelement

1 from selenium import webdriver

2 driver = webdriver.Firefox ()

3 driver.get("http :// google.com")

4 fld=driver.find_element_by_id(’gbqfq’)

5 fld.send_keys(’Anonimowi Admini ’)

badumm tsss

Something more complicated

Show me the code

What the fsck?

Problem? HTML injection

I the id is a hash of something... different everytime

I Let’s get the RichEditor’s class

1 e = "table.ms -formtable > tbody >

2 tr:nth -of-type (7) > td.ms-formbody >

3 span[dir=’none ’] > div >

4 div:nth -of -type (2)"

5 c=driver.find_element_by_css_selector(e)

6 .get_attribute("class")

Problem? HTML injection

I We can not use webdriver.send keys() on that... it’sinside the html code

I We have to inject HTML with javascript

1 JS="document.getElementsByClassName ({0})[{1}]

2 .innerHTML =’{2}’".format(

3 CLASS_NAME , INDEX ,

4 "<marquee > WTF </marquee >"

5 )

6 driver.execute_script(JS)

Clicking a radio button

1 driver.find_element_by_css_selector(

2 "input[type=’radio ’][value =’{0}’]".format(

3 "Approved by the CEO"

4 )

5 ).click ()

Selecting a dropdown option

1 driver.find_element_by_css_selector(

2 "option[value =’{0}’]".format(value)

3 ).click ()

Sending the form

1 driver.find_elements_by_css_selector(

2 "input[value=’Save ’][type=’button ’]"

3 ).click ()

Many python, such win

I 208 lines of Python

I virtualenv

I selenium for browser automation (pip install selenium)

I click for easy commandline (pip install click)

I path.py just because (pip install path.py)

I YAML for templates (pip instal pyYaML)

I keepass for credentials (pip install keepass)

outcome, further plans, other uses

Outcome

I It took 3hrs to write

I It eared it’s keep after one day

Further plans

I webdriver.PhantomJS() for headless operation

I ansible integration

Other uses

I e.g. testing how long it takes the user to perform some action
