Since Japa supports TypeScript with ts-node, what if we have test decorators?

Guys I've tried to open an issue as a feature request in @japa/runner repository, but the link is broken, it keeps redirecting to new issues page.

I miss a lot of writing tests using classes in Node.js. I've already done a very basic implementation on top of @japa/runner, but I think is not a very nice implementation since I'm not exposing the Japa test class and group class API. Writing tests using classes is easier to organize and read the code. We could also use inheritance to set up hooks and other tests defaults in some BaseTest class.

Some example of how I imagine it:

import { Test, TestGroup, AfterAll, BeforeEach } from '@japa/runner' // <- @japa/core maybe?

@TestGroup() // <- Expose group API via options
export class MyTest { // Class name would be the default group name
  @BeforeEach()
  public async beforeEach() {
    // do something
  }

  @AfterAll()
  public async afterAll() {
    // do something
  }

  @Test() // <- Expose test API via options
  public async shouldBeAbleToRunThisTest({ assert }) {
    assert.equal(1, 1)
  }
}

Another way to expose the group/test API options would be using other decorators like @Pin() and @Timeout()
