COURSE OUTLINE

• Introduction - An introduction to different testing techniques. Unit Testing, System Testing, Continuous Integration, Capacity Planning and other testing Techniques
• Unit Testing - Introduces Unit testing, code coverage tools, focusing on eunit.
• Mocking Frameworks - We explain why they are needed, and introduce meck.
• Property-Based Testing - Introduction to PropEr, and property-based testing in general.
• Common Test - An introduction to how the system testing and verification with Common Test works.
• Load - Looks at load testing, back pressure and load regulation. How should systems be load tested, what should you be looking out for, and what do you need to do to stop them from breaking.

ABOUT THE TRAINER

Stavros Aronis

Stavros's experience with Erlang started at the deep end of the pool, when he picked Dialyzer, the famously "never wrong" tool, and made it even smarter, as a master thesis project under the supervision of Kostis Sagonas.

He then made Dialyzer faster and parallel, an improvement which has been included in the Erlang/OTP distribution since 2012. Later he got his PhD by re-engineering Concuerror, another tool for Erlang developers, focused on finding concurrency errors in programs and protocols.

Stavros loves testing and making tools and is now trying to bring all his favorite techniques into industry as an Erlang Solutions consultant and trainer.
