Unit Test

Vise apps currently use vitest to do unit test. Visit vitest website for the detail of ‘vitest.config.ts’.

Unit test convention

Comprehensive TypeScript & ESModule

All source code should use TypeScript & ESModule, including unit test code.

Unit test file convention

Unit test files should have a name like ${modulename}.spec.ts and locate in __test__ folder where the tested module existed.

Example:

├── modules
│   ├── module-a.ts
│   ├── module-b.ts
│   ├── __test__
│   │   ├── module-a.spec.ts
│   │   └── module-b.spec.ts

Caveat

Some meta data such as import.meta.url used by Vise and vite is not supported by tools like ts-jest. Currently the solution is putting them in a single file such as src/data/ent.ts and mock it during test.
