Missing types from vitest/runners module

[aleclarson]

Any types used by VitestRunner or a subclass thereof should be exported from the vitest/runners module.

Some examples of currently missing types include:

• SerializedConfig (used by VitestTestRunner constructor)
• Task
• TaskResult (used by Task.result property)
• ErrorWithDiff (used by TaskResult.errors property)
• VitestRunner (extended by VitestTestRunner class)
• etc

This will make it more convenient to subclass an existing runner. Currently, I have to declare my own types, which is inconvenient and a bit noisy.

import { VitestTestRunner } from 'vitest/runners'

type SerializedConfig = ConstructorParameters<typeof VitestTestRunner>[0]
type Task = Parameters<VitestTestRunner['onAfterRunTask']>[0]
type ErrorWithDiff = Exclude<Exclude<Task['result'], void>['errors'], void>[number]

export default class extends VitestTestRunner {
  constructor(config: SerializedConfig) {
    super(config)

    /* ... */
  }

  onAfterRunTask(test: Task) {
    /* ... */
  }
}

All these types are available from vitest

Ah great, thank you. This wasn't mentioned in the docs page about custom runners: https://vitest.dev/advanced/runner.html#test-runner

Also, I don't see VitestRunner exported anywhere?

No VitestExecutor either. (Found this one in vitest/execute)
