  How To Leverage Ruby's Functional Programming Capability

  Ruby is a multi-paradigm programming language. It fully allows writing old-fashioned procedural code, but also provides many useful constructs and features from the functional world.

  The majority of developers come to Ruby from the imperative world. They are used to making many local variables, changing their state and relying on implicit dependencies. Very quickly, it becomes clear that code can be much more expressive, using powerful idioms from functional languages. Ruby isn’t a fully functional language by any means; functions are not first class citizens, evaluation flow is not lazy, pattern matching support is very limited, etc. But still, it is possible to write code in a functional way and garner many benefits as a result.

  In the field of testing, there are many ideas and movements, some of which have formed into schools. But there is really no universally accepted standard for what testing is and how it should be performed.

  The attempts to establish such a standard (such as the infamous ISO 29119) are met with either ice-cold indifference or hell-hot opposition. Why? Well, because professional developers want to be able to choose approaches and tools that fit particular projects, time frames, budgets and business goals, and deep down they know they will continue to do what’s best to perform their duties well.
