Locator etiquette

how to find elements on a page

they recommend using ID to find the element

Resilient: element_by_name

less good: find_element_by_css_selector

brittle: find_elements_by_xpath

very brittle: to find an element by text content, i.e.. 'sign up today'

data- attribute selector, new in selenium. can work well also

Using Selenium with CBT's Cloud

First test locally. It's quick, easy to learn.

Then it's easy with minimal changes run the tests on CBT's device cloud.

Add authentication, and capabilities and define browser parameters

Demo is in Python

He adds a lot of sleeps to the driver so that he can see what's going on (time.sleep(3) in Python.

creates a Chrome target with driver = web drive.Chrome() then uses driver to talk to the browser

Then adds a try and finally.

You need to make sure you start up and shut down your browser.

Responsive test

uses driver.get("http://..") to get a page.

then driver.set_window_size(...)

Responsive test plus look for items on the page

driver_find_element_by_css_selector("[data-name]")

and also does

driver.execute_script("...javascript...", e) where e is the found element

you can for example scroll with execute_script

there's also plural

driver.find_elements_by_css_selector

chains:

driver.find_element_by_name("username").send_keys("fff@dd.com")

and for the button:

driver.find_element_by_css_selctor("#button").click()

To continue

Then you need to check somehow that you successfully clicked on the element.

He uses wait until

webdriverwait(driver, 10),until(EC.presence_of_element_located(by.XPATH('path selector')))

Move to a bigger framework

to run on a cloud service

the code is on GitHub

My question:

- best strategy to wait for elements/pages to load or appear (I'm using webdriverio)

- using screenshot compare (to further automate checking the results)
