Property Based Testing: From Theory to Practice
summary
An introduction to property-based testing, explaining the approach that originated with QuickCheck and how it finds bugs with few lines of code without enumerating all edge cases. The talk shows practical examples in JavaScript (using the fast-check framework) ranging from simple algorithms to GUI tests, and notes the examples can be adapted to other languages.
