Here’s a secret: it’s not for the tests. Learn about the actual goal and values hidden under the surface of Test-DrivenDevelopment. Test-DrivenDevelopment (TDD) is a controversial topic amongst developers. It is a vehicle to drive development. TDD and the Values of XP.
Developers unimpressed by the early returns of generative AI for coding take note: Software development is headed toward a new era, when most code will be written by AI agents and reviewed by experienced developers, Gartner predicts. That’s what we call an AI software engineering agent. This technology already exists.”
My guest for this interview was Sebastián Ismael, a software professional and visiting lecturer from Argentina. Sebastián has been been with Grupo Esfera, a boutique software consulting company in Buenos Aires, for eight years. The firm serves very large companies in Argentina and elsewhere.
Test-DrivenDevelopment is one of the few truly new Agile ideas. Originally created by Kent Beck as part of Extreme Programming, it’s a fantastic way of making sure your code does what you intended it to do. Test-DrivenDevelopment. ?? Fast, Reliable Tests. ?? Reading: ?? Spike Solutions.
Test-DrivenDevelopment (TDD) is a technique for building software that guides software development by writing tests. It was developed by Kent Beck in the late 1990's as part of Extreme Programming. Write the functional code until the test passes.
After selling two companies into large enterprises with lots of legacy software, Lawler witnessed firsthand how developers were struggling to understand the systems they were tasked with improving, and finding it difficult to deliver fast and secure code in complex microservices and cloud applications.
This is a pre-release excerpt of The Art of Agile Development, Second Edition , to be published by O’Reilly in 2021.

Programming is as much an art as it is a science. Personal preference plays a large role in determining your programming style, so you may not be surprised to find yourself in a debates with a peer. The goal is to better understand these programming methods and be prepared to use them when it makes sense. Functional programming.
Submit a proposal for a talk at our new virtual conference, Coding with AI: The End of Software Development as We Know It.Proposals must be submitted by March 5; the conference will take place April 24, 2025, from 11AM to 3PM EDT. When tools like GitHub Copilot first appeared, it was received wisdom that AI would make programming easier.
This post is a brief commentary on Martin Fowler’s post, An Example of LLM Prompting for Programming. There’s a lot of excitement about how the GPT models and their successors will change programming. Writing these prompts requires significant expertise, both in the use of ChatGPT and in software development.
Kent Beck concluded , Measure developer productivity? We use Extreme Programming as our model of how to develop software. They also love test-drivendevelopment, pairing, continuous integration, and evolutionary design. They tend to be passionate, senior developers. Not possible. And were an XP shop.
Nine years ago, I was eager to be a developer but found no convincing platform. This led to my career as an Android developer, where I had the opportunity to learn the nuances of building mobile applications. Web Development Web Development : Focuses on building the user interface (UI) and user experience (UX) of applications.
To keep pace with the growing complexity of software development, organizations have spent years working to implement agile practices into their developer experience. In this article, Mik explains common misconceptions about agile development and how to properly apply and develop an agile culture.
I recently found out about the book DeveloperTesting – Building Quality Into Software by Alexander Tarlinder , and I immediately wanted to read it. Even though I am a developer at heart, I have always been interested in software testing (I even worked as a tester for two years). What ILiked The Most.
I recently finished Effective Software Testing – A Developer’s Guide by Maurício Aniche , and I really liked it. I have been coding for a long time and I think I have been writing pretty good tests for the features I have implemented. He has also worked for several years as a developer.
When I first heard about TestDrivenDevelopment (TDD) I immediately wrote it off as a technique that will slow me down, how on earth should I know exactly what my code will look like if I often refactor while coding. Even now when I ask developers what they understand about TDD that is the response I receive.
One such initiative involves developing a toolset for assessing a customer’s situation. However, the purpose of this blog is not just to describe the toolset, but to share our development approach and some valuable lessons I (re)learned along the way. At Xebia, we implement numerous internal initiatives.
Which books should you read as a software developer? Software Developers Should Read the Right Books. To save you from mistakes I’ve made, I’ll share five books that accelerate your growth greatly as an ambitious software developer: Apprenticeship Patterns : Guidance for the Aspiring Software Craftsman.
On October 16th, at the Pacific Northwest Software Quality Conference in Portland, I’ll be presenting a half-day workshop on using test-drivendevelopment without mock objects. This is a great session for programmers who want to learn new ways to improve their tests. Are your tests slow and brittle?
However, one of the growth challenges we have is that our backend is primarily written in Clojure, and few developers know Clojure. Before joining CircleCI, I was a JavaScript developer. Functional programming. The primary way this manifests itself in Clojure is through a functional programming style. Everything is data.
One of the success factors for Agile and DevOps is developers changing the way they work and adopting practices like Test-DrivenDevelopment (TDD). This article outlines some of the things that actually do work and explains “Samman,” which is a coaching method used with developers. By Emily Bache.
Natural languages, on the other hand, are infinitely more expressive than programming languages, query languages, or even a UI that users interact with. With ML, you have to start with production to generate your tests. Even bootstrapping with early access programs or limited user testing can be problematic.
TDD is an Agile Development technique in which developers write test cases before writing the corresponding code for the user story assigned to him. Once the code passes the Acceptance test, the code is then refactored /simplified to be used as production code. What is the primary goal of TestDrivenDevelopment (TDD)?
I like to use Test-DrivenDevelopment (TDD) when coding. Writing tests only makes sense after the solution is viable. Last week, I came across examples of where I developed new functionality without using TDD. Last week, I came across examples of where I developed new functionality without using TDD.
Kent is the creator of Extreme Programming, the groundbreaking Agile method that introduced evolutionary design, test-drivendevelopment, continuous integration, and many other Agile practices to the world. It’s the basis of most of the material in The Art of Agile Development. What does it look like in practice?
James Shore, Alternatives to Acceptance Testing. During the software development process, the goal of eliminating defects while you’re writing code is less costly rather than fix bugs later on. Preventing Programming Errors with TDD. I would recommend getting his book too, The Art of Agile Development.
Test-DrivenDevelopment (TDD) is an essential skill for agile teams. Without it, codebases quickly lose the flexibility needed to support agile development. But for coaches, Scrummasters, and other leaders without a programming background, how can you introduce this foundational skill?
The COBIT exam is offered by a variety of vendors — some include training or bootcamp programs if you’re not familiar with COBIT 5, while others will let you just take the exam. This includes developing and maintaining cyber security programs, business analysis, strategic planning, and management tools.
In the past, we have proposed observability-drivendevelopment as a way to maximize your observability and supercharge your development process. But I have a problem with the terminology, and it is: I don’t want observability to drive your development. What is observability-drivendevelopment?

Once we've found a seam, we can use it to break dependencies to simplify testing, insert probes to gain observability, and redirect program flow to new modules as part of legacy displacement. His definition: “a seam is a place where you can alter behavior in your program without editing in that place”.
Armed with a few assumptions about how things should work, I embarked on developing an application with a graphical UI and a backend. To tackle each operation, I started with a small test, following the principles of Test-DrivenDevelopment (TDD). If the tests became too complex, I knew something was missing.
Test automation is one of the practices that helps teams gain confidence earlier in the development process. It reduces the cost of testing and supports keeping long-term, high-development velocities. This results in a steadily-growing set of tests becoming part of the development cycle. Lower-level testing.
Few budgets can meet the continuous need for up-to-the-minute learning and training, particularly in fast-evolving tech areas such as programming languages, software development, containerization, and cloud computing. They’re adding community-driven learning to their existing training approaches. A fresh approach is needed.
Experiences like these make many developers think about using Behavior-DrivenDevelopment (BDD). BDD emphasizes collaboration between developers, testers, and stakeholders to define and deliver software that meets business requirements. Increasing feedback and the delivery of value by working in rapid, small iterations.

Carlos is a software crafter with almost two decades of experience in software development and has been involved with the Software Craftsmanship community for more than a decade. I recently had the pleasure to interview Carlos Blé from the Canary Islands in Spain.
But only rarely does anyone help the developers change too. The developers and the testers have at least as much to learn, and need as much support as do the managers and business analysts. Many developers only know how to work this way; many see the XP practices as counter-intuitive, if they’ve even heard of them.
In this post, I would like to discuss the importance of static types in functional programming languages and why TypeScript is a better option than JavaScript when it comes to functional programming due to the lack of a static type system in JavaScript. Life without types in a functional programming code base.
