LLD - Design — Food Delivery System
How can a delivery system test simulate service coordination failure to improve system robustness?
ABy increasing font size in the UI
BBy injecting network delays and message loss in tests
CBy adding more delivery trucks
DBy disabling user authentication
Step-by-Step Solution
Solution:

  1. Step 1: Understand failure simulation goals

    Simulating failures helps test system behavior under adverse conditions.

  2. Step 2: Identify effective failure simulation methods

    Injecting network delays and message loss mimics real coordination failures.

  3. Final Answer:

    By injecting network delays and message loss in tests -> Option B

  4. Quick Check:

    Failure simulation = network issues injection [OK]
Quick Trick: Simulate network faults to test coordination robustness [OK]
Common Mistakes:
MISTAKES
  • Confusing UI changes with failure simulation
  • Adding physical assets unrelated to software tests
  • Disabling security features unnecessarily
