I’m a Software tester since 11 years now, formely being a developper. I’m still passionate about this activity and enjoy talking with testers of all types and around the world.
This allows me to progress, gives me idea for personal improvements of my skills and confront my ideas based on my professional experiences.
I am now a Freelancer, in Lyon or as a remote, depending on the customer needs.
Otherwise I like sports, running, biking, read and spending time with my lovely family.

Manage your biases as a tester – Part 1/4

Manage your biases as a tester – Part 1/4

It is a long time  since I wanted to write about cognitive biases. I have been first made aware of it while reading this fascinating book “Thinking, fast and slow” by Daniel Kahneman (not a newbie, he won a Nobel prize), and with several blog posts or articles (references at the end). A list of all cognitive biases is available on wikipedia, but this is such a huge disorganized “tangled mess” that the task of writing about biases in Testing frightens me, and I have to admit that I procrastinated doing it. And then a blog post from Buster Benson (Product at SlackHQ) saved me. Thanks to his paternity leave, he decided to organize the mess and found four problems that biases help up to address: “Too much information”, “Not enough meaning”, “Need to act fast” and “What should we remember”. And now everything is almost crystal clear…at least if you go and read this.

An awesome visualization has been done by John Manoogian III and has been since added to the wikipedia page.

Bug magnet, a tool to ease testing

Bug magnet, a tool to ease testing

Let me introduce you a tool I really find convenient. As a tester, you like to use heuristics for all kind of data you need to fill. Let’s talk about a simple example, a form where you need to enter your name, your address and a text.

You will test this with empty fields, very long text, SQL injection, Special characters, End-of-Line characters, text where numbers are only required and probably also with several encodings, etc  (See this Test Heuristics Cheat Sheet for more ideas). If you don’t have a UI framework that test this with data, then you need to enter this “manually”, or you can be helped by a tool like “Bug Magnet” available in the Chrome Store.

Then simply with a right click you will be able to add:

Misconceptions about software testing

If you are reading this article, there’s a good chance that you are working as a software tester or intend to. Congratulations…and sorry for you. Why should I be sorry for you? Because this is far from being the easiest job in the world and you probably have to defend your positions and idea almost every day. However, if you’re passionate about your job, then I’m sure that it’s a kind of pleasure to discuss about it, argument with people having a different point of view and explain them why you can congratulate yourself about having made the good choice with this activity.

So what are the misconceptions about Software testing you may have to discuss?
