"this.ctx.handleFileChanged is not a function" error stopping tests refreshing with latest Vitest beta, 3.0.0-beta.2

[seaders]

Describe the bug

The format of Vitest from vitest/node has changed with Vitest's latest beta and handleFileChanged has been removed in this commit, vitest-dev/vitest@9a1b501#diff-c70ce04cc623628f74475cbde7bf56c29e5c3034b6fd5d26f737cb3944254463L984

99% of the extensions features still work fine with Vitest 3, but this pops up in the Vitest output window, and, if you make any changes to your test file, they won't show up.

This causes a situation where,

• if you change the name of a test and try to run it, it will try to run the old named test
• if you add a new test, it isn't processed nor taken in, so can't be run
• if you delete a test, but run the parent group, it tries to still run that test as well

Installing the previous version of vitest, or 2x, and restarting the extension fixes this.

Reproduction

With having [email protected] and [email protected], and a vite.config.ts file like,

/// <reference types="vitest/config" />

import { defineConfig } from "vite"
import tsconfigPaths from "vite-tsconfig-paths"

export default defineConfig({
  plugins: [tsconfigPaths()]
})

Create a test file - extension doesn't pick it up. Go to vitest sidebar, "Refresh tests", run that test file / some tests therein, add a new test - extension doesn't pick it up.

Output
