A chaos experiment script intended to inject 200ms latency uses injectFault(type='delay', duration=200). The system does not show any delay. What is the most probable cause?

Microservices - Testing Microservices

ALatency injection is not supported in chaos engineering

BDuration value lacks time unit, causing the fault injection to fail

CThe delay duration is too small to notice

DThe injectFault command is deprecated

Step-by-Step Solution

Solution:

Step 1: Check duration parameter format
Duration must include time unit as string, e.g., '200ms'.
Step 2: Identify why delay is not applied
Without unit, the system ignores or fails the injection.
Final Answer:
Duration value lacks time unit, causing the fault injection to fail -> Option B
Quick Check:
Duration needs unit string for injection [OK]

Quick Trick: Always specify time units in duration strings [OK]

Common Mistakes:

Passing numeric duration without units
Assuming small delays are ignored
Believing latency injection is unsupported
