Microservices - Testing Microservices

Consider this simplified test flow for microservices end-to-end testing:

1. Start service A
2. Start service B
3. Send request to service A
4. Service A calls service B
5. Service B returns response
6. Verify final output

What is the main risk if service B is unstable during this test?

AThe test will always pass regardless of errors

BService A will not start properly

CThe database schema will be corrupted

DThe test may fail intermittently causing flakiness

Step-by-Step Solution

Solution:

Step 1: Analyze the test flow and service dependency
Service A depends on service B's response to complete the test.
Step 2: Understand impact of instability in service B
If service B is unstable, responses may vary causing test failures sometimes.
Final Answer:
The test may fail intermittently causing flakiness -> Option D
Quick Check:
Unstable service causes flaky tests [OK]

Quick Trick: Unstable dependencies cause flaky end-to-end tests [OK]
