Introduce test-vitest-setup project to handle test setup for vite tests

---

PR1

• [x] Introduce project test-vitest-setup under the testing folder and add configuration. Copy the example linked below and add potential improvements.
  • [x] adjust coverage.reportDirectory to be at project root (packages/<name>/.coverage)
  • [x] add unit tests
  • [x] use existing types see this comment
  • [x] add minimal docs to the test-vitest-setup project on how to use

Example implementation:

• test-vitest-setup source
• test-vitest-setup usage

---

PR1.2

• [x] Extend vitest.{targetName}.config.ts from test-vitest-setup configuration. (consider the changed reportDirectory may be a breaking change for the CI pipeline)
  • [x] unit tests
  • [x] int tests
  • [x] e2e tests

---

PR2.x - Cleanup and cosmetic cahnges

Preconditions: #1142

Mocks folder

• [ ] Rename nx-plugin/mock to models/mocks
• [ ] Rename examples/plugins/src/lighthouse/mockto examples/plugins/src/lighthouse/mocks
• [ ] After all folders are renamed to mocks adjust inputs in nx.json
  • "!{projectRoot}/@(test|mocks|mock)/**/*"
  • "!{projectRoot}/**/?(*.)mock.[jt]s?(x)"

Mocks creation

• [ ] unify test folder setup and document it. Use the creation from static files instead of generator
  • e2e/ci-e2e/setup.ts#setupTestReop
  • e2e/ci-e2e/test-folder-setup.ts#restoreNxIgnoredFiles

Test Coverage

• [ ] improve test coverage config to exclude as much noise as possible and increase coverage
  • src/lib/index.ts - exclude files that only maintain exports e.g. index.ts (in some places index.ts files also contain actual logic. here I would suggest we discuss per case if we can refactor to have all index.ts used for barrel export only)
  • exclude other files that are not relevant for test coverage

Caching

• [ ] Move zod2md.ts under {projectRoot}/tools and make sure "!{projectRoot}/tools/**/*" is added under nx.json#namedInputs.production
• [ ] remove vitest executor defaults from nx.json in favour of target name as they are conflicting and only one of them wins.

  },

• [ ] To verify: We might have a caching issue with models build.

@BioPhoton PR1 and PR1.2 are covered ~~and at the moment awaiting for your approval.~~

I'm happy to do next step which is PR2 but I'd need more context what is the actual goal of that

[BioPhoton]

Thx @poltorak for the headsup! Feel free to check the boxes in the issue and link PRs. I will be able to add more information to PR2 until Friday-

Sorry it took a while, notification got lost somewhere
