Microservices - Migration from Monolith

Analyze the following pseudocode:

services = ['user', 'inventory', 'billing']
migrated = []
for service in services:
    migrate(service)
    if test(service):
        migrated.append(service)
print(migrated)

What will be printed if all tests pass successfully?

A['user', 'inventory', 'billing']

B[]

C['user']

D['billing']

Step-by-Step Solution

Solution:

Step 1: Understand loop logic
Each service is migrated and tested sequentially.
Step 2: Check condition
If test(service) returns true, service is appended to migrated list.
Step 3: Since all tests pass, all services are appended
Final Answer:
['user', 'inventory', 'billing'] -> Option A
Quick Check:
All services tested and appended [OK]

Quick Trick: All passing tests add services to migrated list [OK]

Common Mistakes:

Ignoring the test condition before appending
Assuming partial migration without tests
Misreading loop order
