Mutation testing

Apr 28, 2016 by Madalina Botez in  Announcements

Enjoy the following series of interviews with the speakers, top-notch software crafters from across Europe, joining  I T.A.K.E Unconference, Bucharest, 19-20 May. Discover the lessons learned and what drives them to challenge the known path in their field. 

Nicolas Fränkel, Software Architect with 15 years of experience in a wide range of contexts, University teacher, experienced trainer and book author will join as speaker I T.A.K.E Unconference 2016. In his talk, he will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, he will describe how Mutation Testing works and how it helps pointing out code that is tested but leave out corner cases.

#1. SHARE TOP 3 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

  • I chose to become a programmer, because during my architectural studies, there was a course on POV-Ray, a ray-tracing software where scenes are described with a language
  • I now avoid not well-understood bash commands after trying to execute a find with exec rm command on a production server and starting deleting the server’s filesystem
  • I value knowledge sharing since I started teaching a very long time ago

#2. WHAT CHALLENGES WILL THE PARTICIPANTS FIND SOLUTIONS TO DURING YOUR SESSIONS @ I T.A.K.E UNCONFERENCE 2016?

During my talk, Mutation testing to the rescue of your tests, ​I will not provide a solution but challenge attendees beliefs. Code coverage is the most talked about metric when we speak about quality, but it​s only quality is that it’s easy to compute. In my code, I will show it means nothing, and provide you something more reliable to work with.

#3. WHAT ELSE WOULD YOU LIKE TO SHARE WITH PARTICIPANTS?

​I’m a Java geek, through and through, but also ski in winter, run, play squash, sketch nudes, write books, and am currently learning Russian and Kotlin.​

Test-Drive your Database & the 4 Rules of Simple Design

Apr 27, 2016
 Enjoy the following series of interviews with the speakers, top-notch software crafters from across Europe, joining  I T.A.K.E Unconference, Bucharest, 19-20 May. Discover the lessons learned and what drives them to challenge the known path in their field. 

 

Alastair Smith, developer at Redgate and founder of the Cambridge Software Craftsmanship Community in the UK and a co-organiser of DDD East Anglia, will join this edition of I T.A.K.E Unconference. After attending his sessions, participants will be able to use their programming language to clearly express a program’s purpose and stop writing the programming equivalent of legalese. They will be able to write unit tests for their own SQL code and enjoy database development again.

#1. SHARE TOP 5 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

The five things that put me on this path were:
  1. Reading software development books hungrily in the first few years of my career. Texts such as Code Complete and especially The Pragmatic Programmer and Test-Driven Development by Example were hugely influential on my early career and the direction I chose to take. The Pragmatic Programmer in particular is worth re-reading: I didn’t fully understand some parts of it as a fresh graduate joining the industry, and the experience I’ve built up over the last ten years has allowed me to get more from it on each later reading.
  2. Attending developer meetups, user groups, and conferences. Aside from the knowledge gained from the talks and workshops run at these events, they’re an invaluable opportunity to meet other developers, learn from their experiences, and about the local software industry.
  3. Finding a good mentor. As it turned out, my mentoring was very unofficial: a former colleague of mine guided me in the ways of professional software development, and pointed me in the direction of books, blogs, and other resources to learn from. His advice was invaluable in helping me discover techniques for writing good tests (and why tests are important), the importance of refactoring, and the foundational principles of Object-Oriented Design, such as SOLID. All of this at the beginning of my career, in an environment where I wouldn’t have otherwise been exposed to such topics.
  4. Understanding people as well as tech. As technical people, we can often be quite blinded to the problems around us and focus on the tools and technologies rather than the underlying collaborations with other people.
  5. Applying principles I’d learned elsewhere to my profession. I play a lot of music, and have been for over 20 years; as such, the idea of deliberate practice is quite a familiar one to me, and applying this principle to the techniques used in software development made a lot of sense. Participating in and organising things like Dojos and Code Retreats has helped me understand and improve my own development process enormously.

 

#2. WHAT CHALLENGES WILL THE PARTICIPANTS FIND SOLUTIONS TO DURING YOUR SESSIONS @ I T.A.K.E UNCONFERENCE 2016?

Database changes are difficult to get right, and objects like Stored Procedures and Functions can be particularly hard to work on. We’ll take a tour of test-driven development, and how we can apply it to our database objects to reduce risk in deployment. We’ll also look at how we can set up a CI server to run our new database tests automatically, just as we would for application code.
We’ve all had to read contracts at various points, e.g. when renting a flat, or borrowing money, or the EULAs that ship with software (and who actually reads those, right?). These contracts are generally written in “legalese”, the language of lawyers that is so concerned with being fully precise, and closing loopholes created by interpretation, that documents written in this language become obscure and the meaning obfuscated.
Just as human languages are a communication tool, so are programming languages, and we have our own form of legalese: code that’s far too concerned with implementation details, such as nested for loops, if statements, etc. Refactoring helps us move away from this, but where should we head? If we’re writing new code, how can we best express ourselves in the code we write?
 

#3. WHAT ELSE WOULD YOU LIKE TO SHARE WITH PARTICIPANTS?

Creativity is an important part of my life: I play the bassoon to a high standard and recently started singing. As well as music, I enjoy cooking, and working with chocolate; photography; and losing myself in a good book. William Boyd is a favourite author, and having recently enjoyed The Hunger Games series, I’m continuing my dystopian fiction streak with the Divergent series.
Similar to the Craftsmanship metaphor for software, I like collecting “real-life” examples of software delivery ideas. Ask me about minimum viable cathedrals, or the early Sputnik launches.
I’m super-excited about Star Wars: Rogue One!
