A practical guide to testing Model Context Protocol servers — the handshake, tools/list and tools/call, schema assertions, error mapping, transport differences, and the security cases unique to MCP.
How to run API tests inside a Kubernetes cluster — Jobs, Helm test hooks, Argo CD PostSync, ephemeral namespaces per PR, RBAC and collecting results.
A Karate framework tutorial for API testing: Gherkin .feature files with no step-definition code, built-in match assertions, Scenario Outline data-driven tests, and running the suite in CI/CD with Maven.
How testing changes between REST, GraphQL and gRPC — contract format, error semantics, security surface and tooling — with the same check written three ways.
Pact vs Postman for contract testing — what consumer-driven contracts prove that schema assertions cannot, where Postman is genuinely enough, and how to run both.
A Cypress API testing tutorial: cy.request() basics, chaining requests with aliases, custom commands for auth, parametrized tests, and running the suite in CI/CD — with working JavaScript for every example.
k6 vs JMeter vs Gatling compared on scripting language, resource efficiency, CI integration, reporting and protocol support — with the same scenario written in all three.
REST Assured vs Karate compared on language, learning curve, parallelism, mocking, reporting and CI — with the same test written in both.
curl vs Postman compared on scripting, reproducibility, CI, debugging and collaboration — with the exact curl flags worth knowing and how to convert between the two.
