The 2-day course “Deep Dive BDD” gives you the background on BDD and where it is most effective. It focuses first on the mindset and process of breaking down big requirements into example specs, and then dives into using Cucumber/SpecFlow to write and execute BDD scenarios. It then goes into testability and maintainability patterns and anti-patterns.
Behavior-driven development is an agile methodology aimed at improving communication between developers, testers, business analysts and others while working on a product. It allows all stakeholders to get a common view of the requirements, what is already implemented and the complexity of the upcoming features. The specs not only direct the implementation of the product but also support the maintainability of the code throughout the lifecycle of the product
The course starts with the origins of BDD and how it was applied in the context of agile projects. We then start to work through examples of how requirements can be defined using Gherkin, a language within Cucumber, the main tool for executing BDD scenarios in Java, as well as SpecFlow for. We learn how to set up scenarios, write and maintain them, as well as write the code to make them run. At the end of the course we’ll have a working application built in BDD.
The course is intended for: Developers, testers and business analysts with software development background.
Course length: 2 days.
