Proper Black Box Testing Case Design – Equivalence Partitioning

In today’s IT world, the lines between developers and QA Engineers are being blurred. With the emergence of Agile, Test Driven Development, Continuous Integration, and many other methodologies, software testing is becoming even more critical. To support daily releases, multiple Operating Systems, and multiple browsers, the Development team (QA and Software Engineers) needs the capability to create test cases faster ...

Why are Constraints Helpful

When people first try scrum, or TDD (or any new process), they feel uncomfortable. We “know how to do” stuff, but then we’re asked to try on something new. Then our comfort zone alarm goes off. We feel constrained. Scrum puts limit on sprints, so we’ll need to actually help the testers finish testing our story. We can’t just continue developing. ...

Git stash driven development

I’ve found myself using a pattern quite often recently, which I’ve been calling “git stash driven development” – that is, relying heavily on the magic of git stash as part of my development workflow. Normally I follow what I think of as a fairly typical TDD workflow: Write next test, watch it fail Write code to make it pass Commit Refactor ...

Do We Really Need Estimates?

Okay, so you’ve read anything I wrote before, you probably know by now, that I am a strong proponent of Agile methodologies. I’ve said it before, and I’ll say it again: Estimates Are Wasteful It doesn’t matter if it was a friendly debate with a manager, discussion with a client, heckling from someone in the audience of a presentation, but ...

This is the final part of the Rebooting ALM series. You should also read: Part I: Evolution Part II: Power Part III: Weakness We’ve covered where ALM tools excel, and where they falter. Now, allow me to fantasize about how we can take a leap forward and start solving actual problems for real ALM users (that’s us). Most of our work starts ...

Rebooting ALM PartIII : Weakness

This is the 3rd part of Rebooting ALM series. You can find the others here: Part I: Evolution Part II: Power Obviously, I wouldn’t call this series “Rebooting ALM” if the tools didn’t have their weaknesses. Let me count the ways. The first problem of ALM tools starts with the customer. The end-user  of the system (developers, testers, business analysts) is NOT ...

Rebooting ALM Part II: Power

This is the 2nd part in the Rebooting ALM series. Check out the first part “Evolution“, to see how we got here. (See what I did?). The first tool, I think, that started the ALM tool chain, was source control. There were compilers, and some IDEs, but source control systems were solutions for team-work. If you think about it, the ...

Rebooting ALM Part I: Evolution

This is the first in a series about Rebooting ALM. I’m going to present this next at Agile Slovenia in a week, don’t miss it. I’ve started thinking about how Application Life Cycle Management has changed over the years. It’s funny, because what’s the first thing they teach you in agile class (I hope)?   “Individuals and interactions over processes ...
