API Testing
Schemathesis takes your OpenAPI or GraphQL schema and automatically generates hundreds of test cases from it — including edge cases your manual test suite never thought of. It finds server crashes, unhandled exceptions, and schema violations that sit invisible in hand-written tests. This guide covers everything from basic setup to stateful
Chaos Engineering
Steadybit is a reliability testing platform that combines chaos engineering with automated discovery of your system topology. It maps your running services, detects their dependencies, and suggests reliability experiments based on what it finds. Where other chaos tools require you to know exactly what to target, Steadybit helps you discover
Chaos Engineering
Pumba is a chaos testing tool for Docker containers. It kills containers, pauses them, and injects network failures using Linux tc (traffic control) — directly on your Docker host or inside Docker Compose environments. If you run microservices locally with Docker Compose or test in Docker-based CI environments, Pumba is the
Chaos Engineering
LitmusChaos is a CNCF-graduated chaos engineering platform built natively for Kubernetes. It uses Kubernetes-native custom resources to define, run, and observe chaos experiments — no external tools, no sidecars, no proprietary agents. Chaos experiments are just YAML that runs in your cluster like any other workload. Why Chaos Engineering on Kubernetes
Chaos Engineering
Chaos Toolkit is an open-source chaos engineering tool that defines experiments as declarative JSON or YAML files. Each experiment specifies a steady-state hypothesis (what "normal" looks like), a set of fault-injection actions, and rollback activities. Chaos Toolkit verifies your hypothesis before chaos, injects faults, then verifies the hypothesis
Chaos Engineering
AWS Fault Injection Simulator (FIS) is AWS's managed chaos engineering service. It runs fault injection experiments against your AWS resources — EC2 instances, ECS tasks, RDS clusters, EKS pods, and more — without requiring agents or sidecar processes. Experiments are defined as templates in AWS, run on a schedule or
Contract Testing
Specmatic turns your OpenAPI specifications into executable contracts that work from both sides: it can run your spec as a stub server for consumer testing, and verify that your actual API implementation conforms to the spec for provider testing. One spec file, both directions — without writing a single test. The
API Testing
Dredd validates that your API implementation matches its documentation. It reads your API Blueprint or OpenAPI specification, makes real HTTP requests to your running server, and checks that the responses match what the spec promises. When your code and your docs disagree, Dredd fails — forcing you to keep them in
Test Reporting
Running tests is table stakes. Understanding what the results mean over time — that's where teams actually improve their quality practice. Test trend analysis is the discipline of reading patterns from test result history: which tests are reliable, which are lying to you, which parts of the codebase have
API Testing
API fuzzing finds the bugs that escape manual testing and code review: server crashes from unexpected inputs, schema violations from edge cases, and authorization gaps revealed by unusual request sequences. But fuzzing without a clear strategy wastes time and generates noise. This guide covers the practices that make API fuzzing
Test Management
Choosing between TestRail and Zephyr Scale is one of the most common decisions QA teams face when scaling their test management practice. Both tools are mature, widely adopted, and feature-rich — but they serve different organizational contexts and workflows. This comparison covers the key differences across pricing, Jira integration, reporting, usability,
Test Reporting
A test report that no one reads is noise. A test failure that doesn't create a Jira ticket gets forgotten. A CI build that breaks but doesn't alert anyone in Slack lets bugs sit for days. Integrating test reports into the tools your team already uses
