Pros and cons of using Test Driven Development for web applications built with Ruby on Rails (RoR)

Folks, to those of you, who have had a tough time in getting yourself clear on the concepts of Test Driven Development (TDD) and doing Web Apps with Ruby on Rails (RoR), here is your opportunity, to get started; all you need to do is, to take a sneak peek into this simple yet easy to read the annotation, on the subject.

Traditionally, application software testing helped fix any bugs/defects in the software, code before its release globally, or to the clients – the goal of test plan was to ensure that the system under test, didn’t fail on any functional or stress grounds, while in operation or otherwise.

However, Test Driven Development or TDD as it is usually termed is a practice of writing the testing code prior to or before one develops the actual application logic.

And this reasoning can go, on and on and you can always wonder: Does the emergent design really work? What if it doesn’t work in some cases? Does TDD really work? Are there any complex applications built using TDD? Are there studies that support TDD as a best practice? So on and so forth.

This incidentally, raises to big questions – i.e., is the TDD going to work fine for Web Apps, built using Ruby on Rails? And the second – is it really, feasible to establish the findings of the implementation team? That consists of a set of dedicated System applications and Software Engineering details of the company.

To begin with, Ruby on Rails helps quick development and frees programmers of any repetitive coding by emphasizing convention over configuration and by adopting agile/TDD development principles.

Also, Ruby on Rails development routines are short and therefore they actually help to facilitate the application of TDD methodologies, suiting well in achieving desired results.
TDD checks the system along these lines

  1. By introducing new features and checking if the system responds well
  2. By checking for system responses when Ruby on Rails works closely with TDD to manage Web Apps with a lot of new features to their end-users who need support to their ever-changing.

Every new feature, mentioned above can potentially inject new defects into the Software application/product code and therefore increasing the scope for malfunction in the system – which means that there is a likelihood of TDD to actually becoming exhaustive to both developers and testers as the business needs change.

However, TDD goes about creating the necessary tests for all these new features (i.e., their code) besides the numerous programs that make for the entire system – thus reducing the scope for any design upfront, almost totally!

Despite having very little scope for design upfront, it has been a well known and established fact with TDD that it actually, renders a simple and very good design, by the time the product is ready for release.

On the negative side, however, it is something that is considered to be unnatural and hard to implement as we need to continuously, keep training ourselves over and over, again on how to think simpler and to ask good questions, all the time. In fact, many of us, find the TDD practices, quite challenging and time-consuming, especially in understanding which/what tests to write?

Industry gurus that have heard about TDD, have tried it and have seen its benefits; State the following reasons on why they wish to continue doing TDD and why they don’t want to leave doing the same.

  1. TDD makes for a controlled and realistic pace of development
  2. It helps in avoiding difficulties for analysts and designers.
  3. Helps build focus
  4. Helps developers to work on small pieces of code only
  5. The tests help them to save them from mistakes and other errors

Finally, there are many companies that use TDD extensively. Whilst, some of them aren’t sure fully about its core philosophy to the improvement of the development process, most, however, know and support TDD and try to see how they can apply the process to arrive at overall success.

The Ruby on Rails community is especially keen on doing TDD. Source
