Narrative: In order to learn to with JBehave using Eclipse As a junior Java developer though senior in .Net and in BDD I want to define the behaviour of a custom stack Scenario: I push an item onto the stack Given I have an empty stack When I push an item 'orange' Then I should count 1 Scenario: I pop from the stack Given I have an empty stack When I push an item 'apple' And I pop the stack Then I should count 0

Narrative: In order to work with files to compress As a guy who wants to win a bet with cameron I want to ensure files are ingested and processed in the manner in which the methods in the ingest class purport to process them. Scenario: Simple test to give JBehave a test drive Given a file, a.log When the caller loads the file as a byte array Then the byte array that is returned contains the correct number of bytes.
