···8899Under the hood Vitest calls `tsc` or `vue-tsc`, depending on your config, and parses results. Vitest will also print out type errors in your source code, if it finds any. You can disable it with [`typecheck.ignoreSourceErrors`](/config/#typecheck-ignoresourceerrors) config option.
10101111-Keep in mind that Vitest doesn't run or compile these files, they are only statically analyzed by the compiler, and because of that you cannot use any dynamic statements. Meaning, you cannot use dynamic test names, and `test.each`, `test.runIf`, `test.skipIf`, `test.each`, `test.concurrent` APIs. But you can use other APIs, like `test`, `describe`, `.only`, `.skip` and `.todo`.
