Testing in a Distributed World

Accompanying repository for the "Testing in a distributed world" talk given at RICON 2014. Feel free to open any issues for questions and/or to say hi :)

Talk Outline

See the image credits and link to slides. The video of the talk is available!

The talk is broken down in 4 main sessions:

• Challenges of testing
• Distributed System Testing in Academia
• Formal Methods (Human Assisted Proofs, Model Checking, Lightweight Formal Methods)
• Scholarly testing (3 highlighted papers)
• Distributed System Testing in Industry
• Highlighted papers
• Conclusions
