🧩 Annotation Usage Guide

Inferno uses a single, powerful annotation: @InjectInferno, which you can apply to any @Controller, @Service, or @Repository method in your Spring Boot application.

This annotation allows you to simulate real-world system failures with minimal effort.

---

📌 @InjectInferno Overview

@InjectInferno(
    mode = FailureMode.LATENCY,
    latencyMs = 1000,
    rate = 0.2
)
public String getData() {
    return "This will be delayed";
}

🔧 Annotation Attributes

Attribute	Type	Required	Description
mode	FailureMode	✅ Yes	The type of chaos to inject (e.g., LATENCY, EXCEPTION, etc.)
latencyMs	long	❌ No	Delay duration in milliseconds (only for LATENCY mode)
rate	double	❌ No	Probability of failure injection. Default is 0.1 (always)

📋 Supported Modes

See all available values for FailureMode in Failure Modes.

💡 Tips

• You can apply this annotation to any Spring-managed method (controller, service, or repo).
• Combine with unit tests or Postman to observe behavior.
• Ideal for testing resilience, fallback logic, and observability tools.
