vitest-codemod

This repository contains a collection of codemod scripts for use with
[JSCodeshift][jscodeshift] that help migrate to [vitest][vitest].

The vitest-codemod CLI is a lightweight wrapper over jscodeshift.
It processes --help, --version and --transform options before passing them
downstream.

Prerequisites

To use vitest-codemod, please install [Node.js][install-nodejs].

Usage

- Optionally execute dry-run for the transform, and print transformed files on stdout:
``console
npx vitest-codemod --dry --print -t jest PATH...
`
- Run transform, and make changes to files:
`console
npx vitest-codemod -t jest PATH...
`
- To use the latest version of vitest-codemod, clear your npx cache. You can either
manually delete folder $(npm get cache)/_npx/*, or run clear-npx-cache.
`console
npx clear-npx-cache
`

Example

`console
$ cat example.spec.js
describe("basic", () => {
test("Math.sqrt()", () => {
expect(Math.sqrt(4)).toBe(2);
})
});

$ npx vitest-codemod -t jest example.spec.js

$ cat example.spec.js
import { describe, expect, test } from "vitest";
describe("basic", () => {
test("Math.sqrt()", () => {
expect(Math.sqrt(4)).toBe(2);
})
});
``
