A Beautiful Day For Unit Tests

Writing unit tests on Legacy Code is an adventure. Today I spent several hours doing that with two developers, Mark and Yelena.

The system has a flow you are used to and when you write code you fit it into this flow. Then you test the entire system.

With unit tests, it works differently. You are required to start the flow from the middle and stop it when your deed was done.

This requires a different level of system understanding. When we started off in the morning we looked at the code and thought “how are we going to harness this?”

Getting Started with ATDD

It is early afternoon on Friday.

As the week is coming to an end, so is Team Alpha’s Sprint.

The team is rushing to finish the last User Stories in the Sprint. Marion is putting the last touches on the Daily Report User Story. Just a bit more tweaking of the CSS… and… we’re done! Marion shoots Kate, the PO, a WhatsApp message: “Hi Kate, the daily report story is done, can you please check it out and accept it?” A couple of hours pass and Kate is finally done with the grueling series of back-to-back meetings she’s been enduring today.

How to go beyond console.log and get the most out of your browser’s debugging console

The console object is a very useful feature of browsers that have been around for many years. It provides access to the browser’s debugging console.
Most web developers know how to print messages to the console using console.log. But I’ve found that many don’t know about other features of the console, even though they can be very useful for every web developer

Peer Code Review – Benefits and Statistics

Benefits and statistics of embedding peer code review into your software development process.

As a Lean-Agile coach, I regularly talk with software development groups about the benefits of adding code review to their development process. Some easily embrace it and some require a little bit of persuasion, but usually, I find enough internal allies to initiate the change. Lately, I encountered a whole group that completely rejected this essential practice as a luxury they can not afford. Explaining that they will see immediate ROI within a sprint or two was not enough to convince them. So, I sat to compose the following list and sent it to the group. Luckily I had a sympathetic ear with the general manager of the business unit who embraced it and made it easier for the team to experiment with the practice. All’s well that ends well… here is the list, shared with you too.
