Erlang eXchange 2008: John Hughes on Quick Check for Erlang
Quick Check for Erlang
Testing is a major part of all software development—yet no matter how much effort is spent on it, some errors always seem to slip through. Cases which no‐one thought to test crash systems late in development or out in the field, revealing errors which cost time and money to analyze, diagnose, and fix. In the worst case, such errors reveal fundamental flaws which force a redesign of part of the system, at disproportionate cost.
In this erlang session, QuickCheck is an automated testing tool which addresses these problems by generating test cases from a concise specification (so that many more cases can be tested), and simplifying failing cases to a minimal example on a test failure (so that fault diagnosis is quick and easy). QuickCheck enables developers to dramatically improve test coverage, and find obscure errors at an earlier stage, lowering costs and improving quality as a result.
