pytanium

A front-end web testing tool in Python

Why

We need a front-end testing tool that combines the strengths of existing tools

Comparison

Features not listed below are assumed to be the same among the tools, ie. cross-browser testing

Capability Description Selenium Sahi Watir pytanium
Easy HTTPS Auto-accept SSL certs Yes Pro only Yes Yes
Prevent alerts/confirms/prompts Doesn't block on these events No Yes No Yes*
Prevent print Doesn't block on print No Yes No Yes*
AJAX waits Waits for AJAX calls to complete No Yes No Yes*
File downloads Allows files to be saved No Yes No No
Relational identifiers Identify objects using in, near, contains etc No Yes No To do
Recorder/Object spy Easy identification of elements Yes Yes No Yes
Languages Programming languages Many JavaScript/Java/Ruby Ruby Python
Cross-domain support Consistent cross-domain support Yes Occasional configuration Yes Yes
Debugging Breakpoints and introspection Yes Sort of** Yes Yes
Technology Browser interaction method Native JavaScript events Native Native

*Works as long as the event isn't triggered before the document is loaded

**Sahi supports running a script line by line. For introspection, JavaScript must be executed while the script is paused.

How

Pytanium uses the python binding for selenium. To provide the features not typically included with Selenium (AJAX waits, blocking print calls, etc), pytanium injects javascript on nearly every call to the browser.

Language Features

Pytanium makes it easy to switch from Selenium, Sahi, or Watir. In doing so, it supports a lot of the same syntax from each of these tools.

Selenium

If you're writing selenium with python you don't have to change your existing code, it's syntactically correct pytanium code.

Sahi

Pytanium's features are heavily inspired by Sahi, so a lot of Sahi's syntax works.

Recorder/Object spy

Sahi has an excellent object spy and recorder. The pytanium recorder leverages this power by simply adding an additional supported language to Sahi.

Download the recorder

While writing automation, it's helpful to inspect objects on a page in the same browser instance we're automating. Opening another browser just to verify an element on a page is cumbersome and slow. To use both the recorder and automation simultaneously:

  1. Start the Pytanium Recorder (A Sahi Open Source proxy)
  2. Pass {'enableRecorder' : True} as one of your capabilities (for Firefox) or desired_capabilities (for everything else)
from pytanium import webdriver

# For Firefox
browser = Firefox(capabilities = {'enableRecorder' : True})

# For everything else
browser = Chrome(desired_capabilities = {'enableRecorder' : True})
browser = Ie(desired_capabilities = {'enableRecorder' : True})
