| .sqltest | turso-test-runner/tests/ | SQL compatibility. Preferred for new tests | | TCL .test | testing/ | Legacy SQL compat (being phased out) | | Rust integration | tests/integration/ | Regression tests, complex scenarios | | Fuzz | tests/fuzz/ | Complex features, edge case discovery |

Note: TCL tests are being phased out in favor of turso-test-runner. The .sqltest format allows the same test cases to run against multiple backends (CLI, Rust bindings, etc.).

You must start converting TCL tests with the convert command from the test runner (e.g cargo run -- convert -o ). It is not always accurate, but it will convert most of the tests. If some conversion emits a warning you will have to write by hand whatever is missing from it (e.g unroll a for each loop by hand). Then you need to verify the tests work by running them with make -C turso-test-runner run-rust, and adjus...
