[TECH] Replace Jest by VitePress

[Romakita]

Information

Vitetest can be used to run test since the unplugin-swc is released and support TS legacy decorator.

Here is an example of vitest.config.ts required to run test correctly:

import swc from "unplugin-swc";
import {defineConfig} from "vitest/config";

export default defineConfig({
  test: {
    globals: true,
    root: "./"
  },
  plugins: [
    // This is required to build the test files with SWC
    swc.vite({
      // Explicitly set the module type to avoid inheriting this value from a `.swcrc` config file
      module: {type: "es6"}
    })
  ]
});

Note: Vitest support workspace https://vitest.dev/guide/workspace.html . It can be interesting to use it on this project to run all test.

Acceptance criteria

• All tests run
• Coverage are updated correctly
