Overall

Test method format: When()
Setup-test-verify pattern. Use inline comment: // setup, // test, // verify

Unit Testing

Assemby: A2.Server.UnitTests
Not everything should be unit tested:
- Test only functions, methods that have well defined input, output or behaviour.
- Test pure functions/classes only. No controllers

Local Integration Testing

Assemby: A2.Server.Tests
MUST use ASP.NET integration tests (WebApplicationFactory, real HTTP client).
MUST fake downstream deps (realistic in-memory, no external calls), never mocks/stubs.
To fake DynamoDB, MUST use DynamoDB local.
Duplication across tests is fine — don't extract shared helpers.
MUST produce four types of tests:
- Type 1: Realistic test data, happy path.
- Type 2: Bad data: extra long string, too short, large integer, negative integer.
- Type 3: Invalid shape data: nulls for required fields, (might need to send RAW json), missing fields, wrong data types etc.
- Type 4: Unauthorized and/or unauthenticaed access.
