Testing in Pharo

I'm an expert in object design, object language design, reflective programming, and the maintenance and evolution of large applications (visualization, metrics, meta-modeling). My work on traits has been introduced in AmbientTalk, Slate, Pharo, Perl-6, PHP 5.4 and Squeak. They have been ported to JavaScript. It has influenced the Scala and Fortress languages. I'm one of the founders of Pharo (http://www.pharo.org/), a new pure open-source object language inspired by Smalltalk. I head its industry consortium http://consortium.pharo.org. I'm one of the designers of Moose, an analysis platform (http://www.moosetechnology.org/). I was one of the founders of Synectique, a company offering dedicated analysis tools.I have written several books on language-related subjects and other topics such as learning to program and web programming: some are available at http://books.pharo.org. I co-constructed a highly acclaimed Moocs on Pharo and object programming: http://mooc.pharo.org and https://advanced-design-mooc.pharo.orgI regularly work with companies such as Arolla, Berger-Levrault, Thales, Framatome, Siemens, CIM, Worldline.I'm interested in understanding how to solve their challenges. Coding enthusiast. Mad hatter. Software engineer and researcher.I am currently an Inria researcher. I am an expert in software engineering. I work in tight relations with the RMoD team from Inria Lille-Nord Europe.My main research interest lies in the efficiency and modularity of programming languages, particularly in Language Virtual Machines (VMs). VMs make it possible for high-level programming languages to run efficiently and thus make them an important asset for companies. They achieve high-performance thanks to aggressive optimization techniques that mix state-of-the-art compilation with operating-system memory management. A main challenge in this context is the high cost incurred in VM construction, due to the complexity and inter-dependence of their many components. This complexity is required by companies and researchers to be competitive.I actively participate in the development of the open-source Pharo programming language and environment since 2010, and I am a member of its technical board since 2018.My main topics of interest are the runtime adaptation of applications, Virtual Machine design and development, and programming language tools. For that, I work on reflective applications and programming languages.
