Gherkin
That's right, JOSF understands your natural language! If you're not familiar with gherkin, the guys at at Cucumber.io [have it all written down] (https://cucumber.io/docs/guides/overview/).
An example of one of our own feature files.
Feature: use Gherkin language to improve Behaviour Driven Development
As we are a backer of BDD,
JOSF enables us to develop feature files, like this one!
Scenario: Reusing step definitions is extremely easy
Given I'm at the grocery store
When I buy milk
And I buy flowers
And I buy bread
Then the total amount is $6.89
Scenario: Data tables are also implemented
Given I'm at the grocery store
When I have these items on my list
| milk |
| flowers |
| bread |
Then the total amount is $6.89
