 - A single logical error can cause many spec tests to fail. To focus on a single test at a time you can use vitest's option `--bail 1` to stop at the first failed test
 - To then run only that failed test you can run against a specific file as use vitest's filters option `-t <pattern>` to run only one case

 yarn vitest --run --bail 1 --config vitest.spec.config.ts test/spec/presets/sanity.test.ts -t attester_slashing
