# Vitest typechecking playground
Finding a way to perform typecheck on vitest using [--typecheck flag](https://vitest.dev/guide/testing-types.html#run-typechecking):
## Setup information
| Path | Has type error is source file | Has type error inside test file |
|---------------------------------|-------------------------------|---------------------------------|
| src/doSomething | ❌ | ✅ |
| src/doSomethingWithTypeError.ts | ✅ | ❌ |
## Learned things
### How to get typechecking on both tests and source files
Include:
```js
test: {
typecheck: {
tsconfig: './tsconfig.test.json',
include: ['**/tests/**/*.spec.ts(x)?'],
},
},
```
in `vite.config.js``
