The test of interest is: in test/FacetA.test.ts.
A series of two times two test cases are there, and they should allow to see:
- A facet calling another one. A single line of call allows to enable / disable mocking to see the thing work fully.
- A facet storing data using storage slots.
The two tests are duplicated twice - once without hardhat-deploy fixtures and another one with hardhat-deploy fixtures.
IMPORTANT: A deliverable which wouldn't work with hardhat-deploy fixtures wouldn't be acceptable, because as soon as you use diamonds setup times skyrocket. Therefore, the deliverable for this bounty must include working examples for both non-fixtured tests and fixtured tests.
