Supporting it.extend from vitest in effect/test #755
Description
What is the problem this feature would solve?
For our large test suite that tests a lot of CRUD operations, it's been pretty crucial to use automatic fixtures - a very fancy vitest feature. This makes it possible to test a CRUD operation that relies on a user object or some complex object already being initialized, and it does so in a way that doesn't require a lot of boilerplate per-test.
What is the feature you are proposing to solve the problem?
Ideally the effect/vitest module supports the .extend method. Currently it doesn't in Effect.
What alternatives have you considered?
