Test-Driven Development (TDD) is a technique for building software that guides software development by writing tests. The most common way that I hear to screw up TDD is neglecting the third step. Further Reading Kent's summary of the canonical way to do TDD is the key online summary.
One of the success factors for Agile and DevOps is developers changing the way they work and adopting practices like Test-Driven Development (TDD). It’s not something that just happens by itself, and many of the “usual” ways of introducing change fail for TDD.

As we write a lot about Agile , CI , and TDD , we had to mention unit testing. This time, we will talk about what unit testing is, why it is part of Agile methodology, and the main benefits of using it. Originally published Jan. If there were ever a time to compartmentalize.
Most of them are okay with writing unit tests while doing new development work or practicing test-driven development (TDD), but it's easy to be disciplined with greenfield development. Most developers believe in the value of unit tests, even if they don't always like writing them.
James Shore, author of the book “The Art of Agile”, wrote an article that covers the alternatives to acceptance testing. Preventing Programming Errors with TDD. I would recommend getting his book too, The Art of Agile Development. Preventing Different Types of Errors. Preventing Design Errors.
TDD is typically part of an agile process. In TDD, a new requirement always starts out as a new, failing test or “specification.” We write the test … Continue reading "Sustainable TDD: Part 1".
Offered by the PMI, the Agile Certified Practitioner (ACP) certification is designed to validate your knowledge of agile principles and skills with agile techniques. The exam covers topics including Scrum, Kanban, Lean, extreme programming (XP), and test-driven development (TDD). Top project management certifications.
When the Agile Manifesto came out 20 years ago, I really liked what it said. Startups were quite agile long before the manifesto used that term. Over the decades as I watched the Agile movement mature, I was often fairly vocal about what I thought were mistakes in its direction. Then you are truly agile.
I am heartened by the surge in TDD training. To me TDD is the 2nd most important thing for devs to learn-ATDD being the 1st TDD’s not just the automation of unit testing. TDD’s formulation of tests, prior to code, drives design. High quality code is easy … Continue reading "What Is TDD?".
This will give you an agility and a capacity to pivot at any moment, from language, paradigm or architecture, to provide the best possible solution that the client needs.
