Keep your product up to date with Spec by Example and Gherkin

We’ve finally got to the point where we can say it out laud—for most of the time our application specification and documentation is out of date.
“How do we compute the total discount, when a user collected a few different discounts?”,
“Is the quarterly update communication of the department sent to people who moved to another department during the quarter?”,
“What exactly means `a week before Christmas` for our global sales promotion?”.
How easy is it to find answers to these questions? Is `I have to check it in the code base` the only answer? How many business decisions have been made according to outdated documentation page on company’s wiki?
This is where Specification by Example shines the most by introducing a concept of Living Documentation—the only technique known to human kind that lets you keep specification of the business logic always up to date. With help of Gherkin language, it makes specification light, clean and reliable. The one we were always looking for.

After the workshop, you will:
• understand what the Specification by Example key concepts are;
• know the difference between TDD, BDD and Specification by Example;
• be able to identify the key areas where Specification by Example bring the most value;
• have a basic experience with Gherkin specification language.
