Vitest集成github action

精神上最好的避难所还是书本：它们既不会忘了你，也不会欺骗你。——罗曼·罗兰

我们已经知道vitest是一个很好用的单元测试框架，我们今天聊一下如何在github action集成vitest

首先我们创建项目

这里我们配置脚本package.json

{
  "scripts": {
    "test": "vitest",
    "test:ui": "vitest --ui",
    "test:run": "vitest run"
  },
  "devDependencies": {
    "@vitest/ui": "latest",
    "vite": "latest",
    "vitest": "latest"
  }
}

简单配置一下ts环境tsconfig.json

{
  "compilerOptions": {
    "allowImportingTsExtensions": true
  },
  "include": [
    "src",
    "test"
  ],
  "exclude": [
    "node_modules"
  ]
}

然后是代码

// src/sum.ts
export function sum(a: number, b: number) {
    return a + b
}

以及单元测试

// test/sum.test.ts
import {expect, test} from 'vitest'
import {sum} from "../src/sum.ts"

test('adds 1 + 2 to equal 3', () => {
    expect(sum(1, 2)).toBe(3)
})

我们执行一遍开测

Github-Id-VampireAchao:simple-vitest achao$ npm run test:run

> test:run
> vitest run


 RUN  v2.1.1 /Users/achao/IdeaProjects/simple-vitest

 ✓ test/sum.test.ts (1)
   ✓ adds 1 + 2 to equal 3

 Test Files  1 passed (1)
      Tests  1 passed (1)
   Start at  16:29:34
   Duration  195ms (transform 46ms, setup 0ms, collect 40ms, tests 1ms, environment 0ms, prepare 35ms)

Github-Id-VampireAchao:simple-vitest achao$ 

然后就是配置CI模板啦

# .github/workflows/ci.yml
name: Vitest CI

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: 18

      - name: Install dependencies
        run: npm install

      - name: Run tests
        run: npm run test:run

然后我们推送到github就可以看结果

https://github.com/VampireAchao/simple-vitest/actions/runs/10868547662

我们再使用一个错误的案例来测试，这里我们说1+1等于3

// test/sum.test.ts
import {expect, test} from 'vitest'
import {sum} from "../src/sum.ts"

test('adds 1 + 2 to equal 3', () => {
    expect(sum(1, 2)).toBe(3)
})

test('adds 1 + 1 to equal 3', () => {
    expect(sum(1, 1)).toBe(3)
})

推送完毕后直接没通过

这里进行了输出：

Run npm run test:run

> test:run
> vitest run


 RUN  v2.1.1 /home/runner/work/simple-vitest/simple-vitest
