awesome, that should make implementing testing much much easier 😄. approving for the sake of progress on this, but I think it might be a good idea to rename mongoSetup.js given that it also has the express setup helper within it.
- Fix Express error handler arity in imageApi (2 params → 4; Express requires exactly 4 to recognise error-handling middleware) - Reset nextFunction mock between tests in scenarioAuth to prevent call-count bleed across test cases - Remove deprecated useNewUrlParser/useUnifiedTopology options from sceneDao that generated driver warnings - Add missing Access document deletion assertion to scenario DELETE test - Replace Object.entries(array).map(([_, doc]) => doc) in user.js with .map(doc => doc._id), which passed Mongoose documents where ObjectIds were expected - Configure no-unused-vars argsIgnorePattern for underscore-prefixed params; remove now-redundant eslint-disable comment in user.js
Add src/test/mongoSetup.js with two composable functions:
useMongoMemoryServer() registers beforeAll/afterEach/afterAll lifecycle
hooks for MongoMemoryServer; useExpressServer(configureApp) registers
beforeAll/afterAll for an Express server and returns a ctx object whose
port is populated at test time.
Replace ~15 lines of duplicated boilerplate in all five test files with
two calls at the top of each describe block. Also fixes a latent teardown
race: the original server.close(async () => {...}) passed an async
callback that Jest never awaited; the helper uses a Promise-wrapped close
so mongoose.disconnect and mongoServer.stop are properly sequenced.

Issue
Solution
Fix bugs and dedupe Mongoose connection code in test suite
Risk
Low. We can rely on the test suite!!!
Potential risk with user.js fix which corrects broken behaviour (user assignment was passing document objects instead of IDs to the query)
