This folder holds some unit tests and a smoke test. These are run by GitHub Actions on every push. There are more tests in fuzzing, benchmarks folders and elsewhere.

• We test with 500+ standards conformance tests known as the Autobahn|Testsuite where we get a full perfect score.
• In the fuzzing folder you will find extensive security fuzz testing under AddressSanitizer, MemoySanitizer, UndefinedBehaviorSanitizer executed by Google on a daily basis.
• In benchmarks folder you can find performance testing - we've done extensive performance testing of every commit since before we even had a single line of code.
• A set of integration smoke tests for testing basic features against real-world "web browsers" (Deno, Node.js and Bun are the "web browsers").
• And of course in this folder you can find the very module unit tests that check individual modules.
• Customers and users indirectly feed us with real world, high scale production testing.
• Semmle perform static code analysis and security testing for us, where we get the perfect A+ score.
