how to use a chai module

[christophe-g]

Hello,

Trying out vitest - so far it looks and works really well. Thank you !

I am trying to use a chai module with viteset, without success.

For instance, how could I integrate https://open-wc.org/docs/testing/chai-a11y-axe/ so that expressions like expect(el).to.be.accessible(); or assert.isAccessible(el); are available in my test suite ?

Including those this at the beginning of a test file fail:

import { beforeEach, describe, it, vi, assert, expect } from 'vitest'
import { chai } from 'vitest'
import { chaiA11yAxe } from 'chai-a11y-axe';
chai.use(chaiA11yAxe);

... the test suite ...

Thanks.
