Exercise 1 vs Exercise 2:

Exercise 1 (real API): Tests the actual system end-to-end. Coverage <100% because some real service paths aren’t hit. Runs slower (~23 s) due to full validation logic.

Exercise 2 (mocked API): Mocks the email service, so all code paths are executed and coverage is 100%. Runs much faster (~1 s) since no real logic or external calls are processed.

API & Mocked Tests and Coverage

Purpose: Validate README requirements for regular tests, mocked email tests, coverage, and runtime comparison.
Status: ✅ PASS
Regular tests (app.test.js): ✅ PASS (27381 ms)
Mocked tests (app.mock.test.js): ✅ PASS (1368 ms)
Coverage gate (both runs at 100%): ✅ PASS
Runtime gate (regular > mocked): ✅ PASS
Regular coverage: lines=100%, statements=100%, functions=100%, branches=100%
Mocked coverage: lines=100%, statements=100%, functions=100%, branches=100%
