In this post you'll read about the difference between writing automated tests & having testing automated, why testing framework or DSL used do not really matter, what does it mean "to free the mandays", how did we approach securing capacity for kick-starting test automation with a big hit.This is the 2nd post in the series. You can find the previous episode here.Just do it (not)!It's a very banal truth that it's very easy to create automated tests, but it's very hard to automate testing.Uhm, wait, what? What's the difference?I can easily create zillion of automated…

In this blog post you'll read about why & how Shedul has started the journey towards Continuous Delivery, what does it have in common with test automation and why 2 weeks are both a little & a lot ...Dunno about you, but I love the warstories. Theory is great, but even the greatest & most thoroughly thought-through ideas do not guarantee a success - it's (almost) all about execution and learning from successes & mistakes (both your own & others'). I have shitloads of my own stories I'd gladly share, but in many cases I simply can't - as a…
"Organic" growth Codebases grow, they never shrink. New functionality chunks appear, old ones very rarely get decomissioned. More code means more complexity, more dependencies, more space for regression & even more troublesome testing - that's sad reality & you can fool yourself with dreaming about full decoupling, atomic services & independent modules, but in majority of cases - this is not going to happen. Back to reality then - you can still consider yourself lucky if: you're not doing big projects (but the series of small ones) or you're doing big projects that are splittable into small increments…
When I was working about my last blog post, the one about outsourcing the pain, I've come up with an idea of one, interesting type of pain software developers tend to forget about. Wait, they don't forget about it, they usually intentionally pretend it does not exist: the pain of massive data inertia. As close to production ..., right? One of the main reasons why developers share their development environments (and cripple their development agility) is their insatiable hunger for data :) Everyone would like a full-blown copy of production database - surely, in 99% data is properly scrambled, but the volume…
Straight to business - I've participated in a very interesting discussion about development architecture recently: which scenario works better & brings more benefit to the organization: each team is responsible for all their deployment / maintenance mechanisms separately (let's call it Scenario A) there's a dedicated DevOps ('Development Architecture') team that is responsible for deployment / maintenance mechanisms (they provide them for other teams) - for the sake of clarity, it will be Scenario B Both solutions have their PROs: In Scenario A: there are minimal external dependencies x-functional team is able to do all their work on their own if their…
Dealing with technical configuration of your apps may be tricky. In a simple case you just slap a text file or two and there's no harm done, but once your solution gets more & more complex, all those pesky files get really cumbersone: keeping the content of them all in sync modifying the large number of them (usually remotely) in virtually the very same moment preparing the dedicated version for every machine (in distributed scenarios) etc. Obviously, manual configuration adjustments should be prohibited - I've already written a blog post or two about that in the past. BUT even if…
Shortening delivery cycle and improving the overall delivery pipeline gets more & more love nowadays. Delivering value more frequently, in a more predictable manner, while remaining truly transparent - who could resist that? That's why 'DevOps' & 'Continuous Delivery' are trending that high in 2014. Quite recently I've had a discussion with a more senior colleague of mine - we were discussing a particular scenario (that had some issues) in the financial market. We didn't have the first person perspective on this particular case, but we had access to some materials that shed some light into whole story - it…
I had quite an interesting discussion about frequent delivery of value via changes in software. The topics itself is not new and everyone who knows the basics of Agile / Lean approach (or just Theory of Constraints) knows that stashing the inventory should be reduced to minimum - one should deliver as frequently as possible (while making sure that delivered chunks actually bring some value), even if it means smaller portions. The Context In this particular scenario I'll write about, team is delivering more than 1 feature in the same time, BUT people work on feature sets in pairs - each…
