Abstract

Replace Jest with Vitest as the Volto unit test runner.

Motivation

Jest is showing its age compared to Vitest. Vitest is the unit test runner that uses Vite under the hood. It uses a zero configuration model, thanks to be Vite-based. It's faster as it is Vite who transpiles the code.

Assumptions

None.

Proposal & Implementation

Vitest shares the same syntax as they use Mocha/Chai we will have to adapt the test setup to meet Vitest requirements and move the mocks to the Vitest style, if needed.

Deliverables

Volto will be using Vitest instead of Jest for running tests.
Documentation on how to migrate projects and add-ons to use Vitest.
Documentation on Vitest.

Risks

None.

Participants

Open for volunteers. This could be easily a GSOC for next year.
