## +24 ## Back To Basics Debugging and Testing ## GREG LAW & MIKE SHAH ### Writing software is really hard. If it’s not tested, it doesn’t work Or at least it will soon stop working. ## WHAT'S development done right is basically testing and debugging. ## GOOD TESTS ARE • Independent • Repeatable Fast ## DIFFERENT TESTS — ALL ARE NEEDED Unit tests. • Integration tests. System tests. • Acceptance • Iteratively / interactively. • Pre-merge (aka Barrier Tests). • Post-merge (aka Continuous Integration). ###### GIVEN ... WHEN ... THEN Given a server with maximum accepted connections. When a new

Enabling Testing of Contract Checks ## PABLO HALPERN & TIMUR DOUMLER ## Welcome What can the Screen Actors Guild and the Writers Guild of America tell run time How to unit test contract-checking annotations (CCAs) How noexcept interacts with unit testing of CCAs. We will go over everything twice! ## About the presenters In Absentia ## Pablo Halpern Unit Testing, CCAs and Exception Specifications CCAs can themselves use the source of bugs and should verify as part of unit testing. • Overuse of noexcept can interfere with such unit testing We've
