Test Driven Development (TDD)

The reason a development method like TDD helps development is because we want to structurally write high quality code that’s readable, maintainable and most importantly, does what you want it do to and not more or less. Unfortunately, the traditional way of developing is to just think hard about a problem, come up with a solution in your mind and start writing code. And that’s not a good recipe for a good solution. So, after writing some code, we start debugging it and changing it until we think it’s correct and doesn’t produce any obvious errors.

Short summary

The problem is that the solution that pops in your head first isn’t necessarily the best or complete solution, and perhaps isn’t the best next step to take. However, it often does feel like it is. We humans have the tendency to overestimate our abilities and programming is not an exception on this. If you have a lot of faith in your own mind, I’d recommend reading “Thinking, fast and slow”, written by Daniel Kahneman. After reading this book, you stop putting so much faith in the humans’ ability to rationally think about problems and start questioning your own judgment some more.

And that’s where Test Driven Development can help. It forces you to incrementally develop your solution in small cycles by making every outcome of a step explicit and think about the simplest order of steps to come up with your solution, not more and not less. To make the verification of the outcome of a step fast and easy, we use unit tests which we can run a couple of times each cycle. In TDD the developer works in a cycle where he first writes a failing test, then makes it pass and finally refactors the code. This approach prevents the developer from doing multiple things at once which can lead to errors.

If you as a developer don’t practice Test Driven Development yet, this training will help you to really understand what TDD is all about and to be able to apply it in your development work.

Which languages do you offer your courses in?

Our rule of thumb for courses in the Netherlands is – the course is in English unless everybody speaks Dutch, then the course is in Dutch.

What do the costs include?

Unless mentioned otherwise, the course fee includes the cost of training material, exam cost, the use of the location, catering and parking.

Only one or two locations are visible. How is that possible?

The costs that apply to our programs initiated from the Netherlands are exempt from sales tax as per Article 11-1-o of the 1968 Sales Tax Act. In other locations/countries, the prices shown are excluding VAT, which will be added.
