Our process

Make user storieswrite out all the different actions users can and can’t do

Write out Acceptance testsUsing Rspec/Steak

Run the tests!Doesn’t do much but its working!

Write out the first scenarioDo this before you actually create the feature

Run the tests!And it fails! But we where expecting that...

Go ahead! Create that feature!Yeah boi, its hammer time!

Run it again and... no failures!Yippy!

That wasn’t too hardLets step it up

Write out the second scenario

Visit the page

Specify area with CSS expression

Click on the link

Make sure you end up where you expect

Run tests: Red, green, refactorhttp://www.flickr.com/photos/tasuki/3503304405

Wow that was awesome!Yeah I know right!

Whats the difference?

Its way faster!http://www.flickr.com/photos/scallop_holden/2203771977

Speed speed speeeed! (our test suite takes 30 minutes to complete on a fast machine using a headless web browser)

Easier to set up the environment and test edge cases.

Abstracted so easy to change out for different browser in the future.
