Testing

##rspec http://www.neo.com/2013/12/20/custom-failure-messages-in-rspec-given
test by level
tests give feedback on the design integrations tests are a scam
build a safe zone with unit tests and only use integration tests at the boundaries with vendor libs
functionnal tests / acceptance tests
mutation tests
fuzzy tests

Mistakes

fix it now find the root cause of the bug not the symptom
covers it with a unit tests

after

is this code easy to change? -> should be thought in design http://saikuro.rubyforge.org/
benchmarks https://github.com/MiniProfiler/rack-mini-profiler https://github.com/tmm1/rblineprof check sql queries done underneath
