Nowadays the emphasis of the IT and tech industries is on developing newer paradigm than those that have been used for a long time now. Open source programming for automation is all the rage nowadays. Developing software is fundamentally an exercise in making the vague and unknown sufficiently precise to make a machine behave properly. Behavior Driven Development is such an approach to software development designed to address just this problem. With Behavior Driven Development, we begin development of each feature with the desired new behaviour, specifying that behaviour with concrete examples, and making those examples executable as automated tests. Only after we have a failing test – the desired behaviour currently unsatisfied by the system – do we consider implementing the behaviour. Today there are several tools which support the Behavior Driven Development system of which one is called Cucumber. Cucumber training in Chennai is done on a good scale and with good trainers.

The cucumber was originally a Ruby tool. The Ruby version of Cucumber is still the reference implementation and the most widely used, but there are now versions for Java, .NET, JavaScript, as well as several other languages and platforms. Specifications written for Cucumber have two parts: feature files containing scenarios expressed in the Gherkin language and Ruby files containing unobtrusive automation for the steps in the scenarios. This would be followed by a number of scenarios to elaborate how the feature ought to behave. Chennai is a good hub for training in this language.

How training in Cucumber has its benefits

Cucumber is optimized for Behavior Driven Development. It supports a particular set of interactions between team members and stakeholders. Cucumber’s automation means product people are more likely to engage with features and scenarios. The syntax of Cucumber scenarios imposes some structure on scenarios while leaving plenty of room for teams to grow their own language to describe their system. Similarly, the use of regular expressions for mapping between steps and step definitions leaves you room for flexibility in language but naturally limits how much flexibility you employ, lest the regular expressions become unreadable. The Background and Scenario Outline features support simple refactoring to remove excess duplication. But more complex structures such as procedure calls and includes are left out because they would hurt readability for non-programmers. As a functional testing tool for most programmers, it works best when they want to assign the particular functions that they want the software to perform and can know in precise detail, the ways in which the software will perform under most conditions. Most software projects involve teams of several people working collaboratively together, so high-quality communication is critical to their success. Good communication isn’t just about eloquently describing your ideas to others; you also need feedback to ensure you’ve been understood correctly. Cucumber helps facilitate the discovery and use of a language within the team. Cucumber test removes many misunderstandings long before they create any ambiguities in the code.
