- Given precondition
- When Action

- Cucumber is an open source tool for test automation
- Used to write test cases in Gherkin format
- Use Regular expressions to match Gherkin to code
- Cucumber step is what wraps the automation code
- Has been implemented in Ruby, Jruby
- It was originally developed for Ruby
- Tests are written in .feature file
- Multiple scenarios
- Each scenario will contain multiple steps
- Each feature should be independent
- Each scenario should be independent
- Scenario outline is powerful - Loop full scenario for each row
- header in the example table should match the variable defined in the step
- Step table - data used all at once - No looping for a scenario
- Gherkin backgrounds - convenient way to make tests shorter, readable
- Multiple
