Pythonic web testing
Bromine: pythonic web testing
Bromine is a wrapper around selenium to allow writing testing in a terse and pythonic rather that java-esque way.
Selenium is cool: you register browser to a hub, you ask browsers from a hub, you use the browser, and you put it back. It works like magic.
Except if you want to use https. But who needs https these days?
Anyway, enough dissing well intentioned web testing systems. Let's talk bad about bad testing system. You know what you have to do to wait for a page to load after a get, and then check if an element is visible? The selenium docs will tell you:
from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC # ... driver.get("http://example.com") element = WebDriverWait(driver, 10).until( EC.presence_of_element_located((By.ID, "myDynamicElement")) )
I've been kind and I've stripped some boilerplate. If you are happy about
importing three objects from 4 levels of namespaces and create a wait object
and pass a 2-element tuple to the "convenience method"
for a thing you have to do pretty much every time you click on a link, please
stop reading here: type
pip install selenium and off you go. The following
paragraph is only for people who think the above is unsatisfactory in Python.
Still reading? Sure?
Well, I'll be honest: what I prefer to do is:
import bromine browser = bromine.Browser(driver) element = browser.get("http://example.com/").wait(id='myDynamicElement')
