Serenity BDD vs. Spock Framework vs. Unlambda vs. VBScript Comparison Chart

Serenity BDD helps you write cleaner and more maintainable automated acceptance and regression tests faster. Serenity also uses the test results to produce illustrated, narrative reports that document and describe what your application does and how it works. Serenity tells you not only what tests have been executed, but more importantly, what requirements have been tested. One key advantage of using Serenity BDD is that you do not have to invest time in building and maintaining your own automation framework. The aim of Serenity is to make it easy to quickly write well-structured, maintainable automated acceptance criteria, using your favourite BDD or conventional testing library. You can work with Behaviour-Driven-Development tools like Cucumber or JBehave, or simply use JUnit. You can integrate with requirements stored in an external source (such as JIRA or any other test cases management tool), or just use a simple directory-based approach to organise your requirements.

Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.
