Python and WebDriver
Leveraging complementing technologies ...

2. Prerequisites WebDriver basics Basics of programming Example code:
Python 2.7
Unittest

3. Python = Simplicity! Minimise Ceremony Ramp up testers quickly
What we need to do before we can do what we want to do
Ramp up testers quickly
Intuitive syntax (mostly!)

4. Use the power of the shell
Useful
to quickly build tests
Debug failing tests
validate locators

5. Triple A pattern
Arrange (& Destroy afterwards)
Act
Assert

6. Locating Elements BY Selectors Art and Science id name
CSS = I use these where possible
even if ‘id’ present for consistency
Art and Science

7. Page Objects Refactor tests to reduce maintenance Keep ‘em DRY
Beware copy / paste
Locators designed as tuples
Locator type
Locator value
Need to explode tuple to consume it

8. Decorators Functional Programming Functions that
Accept functions
Return functions
Function Inception
Commonly used for logging

9. Descriptors Bind behaviour
Get stuff for free every time you access a variable
Complex topic
Very powerful
Leads to very succinct & DRY code

10. Handling Failure Screenshots Video
grab in the ‘teardown’ only if test failed
Video
Careful Now!
Rerun with a flag on cli to capture video

11. Where Next? Functional Programming Sharpen the saw Docker
Docker
grid
test servers

12. Resources
Read-Eval-Print-Loop
