LLM Testing
Testing an AI agent is not like testing a traditional API. When a REST endpoint misbehaves, you read the logs and find the bad request. When an AI agent misbehaves, you're staring at a black box that made a sequence of decisions — each one plausible in isolation, wrong
Deployment
Blue-green deployment reduces downtime risk by running two identical production environments — blue (live) and green (new). The switch happens at the router level, and rollback is instant: flip traffic back to blue. The testing challenge is making the cutover decision confidently: is green actually ready? The Blue-Green Testing Problem A
API Testing
Kong API Gateway sits between your clients and your services. It handles authentication, rate limiting, routing, transformations, and more — all through plugins. Testing Kong configurations catches issues before they reach production: misconfigured rate limits, broken auth chains, routing errors, and plugin interactions that work in isolation but conflict when combined.

Chaos Mesh is a Kubernetes-native chaos engineering platform. It injects failures — pod crashes, network delays, CPU stress, disk failures — directly into your cluster via Kubernetes CRDs, without modifying application code. The goal is to discover resilience failures before they happen in production. Why Chaos Engineering Your monitoring, alerting, and recovery
API Testing
AWS API Gateway is notoriously difficult to test. Its configuration is spread across stages, integrations, authorizers, and models — none of which is easily testable in isolation. This guide covers pragmatic strategies: unit-testing Lambda authorizers, using mock integrations for downstream isolation, testing with CDK constructs, and integration testing against real Gateway
Security
TLS misconfiguration is one of the most common and consequential security issues in web applications. Weak cipher suites, expired certificates, deprecated protocol versions, and missing HSTS — these issues are easy to find with the right tools and easy to automate in CI. This guide covers the full TLS/SSL testing
Security
OWASP ZAP is the benchmark for open-source web application security scanning. Most teams use it for baseline scans — but ZAP's real power is in its API, authenticated scanning, and deep CI/CD integration. This guide covers the complete picture. Active vs Passive Scanning Understanding the difference determines where
Security
SQLMap is the standard tool for automated SQL injection detection and exploitation. It supports every major injection technique, handles authentication, works with WAFs via tamper scripts, and integrates into CI pipelines. This guide covers practical testing workflows for development and security teams. What SQLMap Tests SQLMap detects and exploits SQL
Security
Nuclei is a fast, template-based vulnerability scanner from ProjectDiscovery. Unlike ZAP or Burp, Nuclei runs predefined YAML templates — thousands of them for CVEs, misconfigurations, exposed panels, and default credentials. The template model makes it easy to write custom checks for your application's specific security requirements. Why Nuclei Speed
Security
Mutual TLS (mTLS) requires both client and server to present certificates during the TLS handshake. It's the standard authentication mechanism for service-to-service communication in microservices, and increasingly used for API access in zero-trust architectures. Testing mTLS is distinct from standard TLS testing — you need to verify that certificate
Security
Certificate pinning prevents man-in-the-middle attacks by restricting which certificates an app trusts. Without pinning, installing a custom CA certificate on a device is enough to intercept HTTPS traffic — the system trust store accepts it and the app never knows. With pinning, the app checks the certificate against a hardcoded list
Android
Room is Android's recommended database library, wrapping SQLite with type-safe query builders and Kotlin coroutines support. Testing Room properly means validating DAO queries, schema migrations, and Paging 3 integration—without ever touching a real disk database. Room Testing Strategy Room provides first-class support for testing through in-memory databases:
