vite-plugin-doctest
Vitest plugin for doctest. You can write test in your source code with documentation.
Usage
/**
* @example
* ```ts @import.meta.vitest
* expect(add(1, 2)).toBe(3);
* assert(add(3, 4) === 7);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
You can also test code in markdown.
# Test
```ts:[email protected]
const { add } = await import('./add');
expect(add(1, 2)).toBe(3);
```
Setup
npm i -D vitest vite-plugin-doctest
// vitest.config.ts or vite.config.ts (js)
import { defineConfig } from 'vitest/config'; // or `import { defineConfig } from 'vite';`
import { doctest } from 'vite-plugin-doctest';
export default defineConfig({
plugins: [doctest({ /* options */ })],
test: {
includeSource: [
'./src/**/*.[jt]s?(x)',
'./**/*.md', // You can disable markdown test by removing this line
],
},
});
npx vitest
Options
Currently, there is no option.
type Options = {}
How it works
This plugin will transform your documentation tests.
This transformation occurs only when you start Vitest. So, you don't need to worry about the performance of your production code.
/**
* @example
* ```ts @import.meta.vitest
* expect(add(1, 2)).toBe(3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
↓
/**
* @example
* ```ts @import.meta.vitest
* expect(add(1, 2)).toBe(3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
if (import.meta.vitest) {
const {assert,chai,createExpect,expect,getRunningMode,isWatchMode,should,vi,vitest} = import.meta.vitest;
import.meta.vitest.test("1+2=3", async () => {
expect(add(1, 2)).toBe(3);
});
}
Constraints
This plugin has some constraints.
- You cannot use typechecks. (e.g.
expectTypeOf
,assertType
, etc...) - You cannot use lifecycle hooks. (e.g.
beforeEach
,afterAll
, etc...) - Currently you cannot use
import
statement in your test code. (You can use dynamic import) - and more... (Please make an issue if you find it)
