Microservices - Testing Microservices

Why is it important to avoid testing multiple microservices together in a single unit test?

AIt reduces test isolation and makes debugging harder

BIt improves test coverage automatically

CIt speeds up the test execution

DIt ensures all services are deployed

Step-by-Step Solution

Solution:

Step 1: Understand unit test isolation principle
Unit tests should test one unit only to isolate failures.
Step 2: Explain impact of testing multiple services together
Testing multiple services reduces isolation and complicates debugging.
Final Answer:
It reduces test isolation and makes debugging harder -> Option A
Quick Check:
Unit tests isolate units to ease debugging [OK]

Quick Trick: Test one service per unit test for clarity [OK]
