By default JGivenGherkin outputs the text to the console:
./jgivengherkin my_test.gherkin
To save it use this command:
./jgivengherkin my_test.gherkin > my_test.java
By default JGivenGherkin uses four spaces to indent. You can change this by opening and editing the following line:
INDENTATION = " ";
- Scenario
- Given, When, Then, And
- String, Integer, Float variables
- English language only.
- Only one variable per line.
- The string variable has to be the last element in the line.
A simple Gherkin file:
Feature: We want to cook our meal
We do this because we are really, really hungry.
Scenario: A pancake can be fried out of an egg milk and flour
Given an egg
And some milk
And the ingredients "flour"
And 3 teaspoons of salt
And sugar for 1.5 Euro
When the cook mangles everything to a dough
And the cook fries the dough in a pan
Then the resulting meal is a pan cakeThe generated Java test:
