# Our Testing
Here at FunFair, we are huge lovers of unit tests. For the Wallet, we have 90% coverage overall and on all the super-important things (like signing) we have 100% coverage. We also have integration tests for signing and other Wallet functionality.
Our QA team provides sign-off on any changes before they go live.
This gives us a great deal of confidence that new releases won't introduce regressions or unexpected behaviour.
