TDDIt’s short for Test Driven Development!

-Kent Beck

“Do the simplest thing that could possibly work.”

From Ticket to Test.

given: when: then:

I’m a user on the profile page

I update my last name

It should save successfully

$ npm test

Run our Test

Fail.

This failure is good.

• We have a test that accurately represents a problem.

• Our test runs

• Not broken nor did it break the test-runner.

$ npm test

Run our Test

Success.
