go-fault
A Go HTTP middleware library for injecting faults like latency, errors, and request rejection into services for resilience testing.
What is go-fault?
Fault is a Go library that provides HTTP middleware for injecting controlled faults into web services. It enables developers to simulate failure scenarios like latency spikes, HTTP errors, and request rejection to test system resilience and error handling. The package integrates seamlessly with standard Go HTTP handlers and allows fine-grained control over when and where faults are injected.
Go developers building HTTP services who need to test failure resilience, particularly those working on microservices architectures or distributed systems where fault tolerance is critical.
Developers choose Fault for its simple middleware-based approach, minimal performance overhead when disabled, and built-in injectors for common failure scenarios without requiring external dependencies or complex setup.
