Testing strategy frameworks by architecture — microservices, SaaS, serverless, and AI-powered applications each need a different approach.
What API functional testing covers, how it differs from non-functional testing, the test design techniques that find real bugs (equivalence partitioning, boundary values, state transitions), a worked example suite and how to automate it in CI.
Is API testing integration testing? Sometimes. This guide explains API integration testing, how it differs from unit, contract and end-to-end tests, how to handle dependencies with Testcontainers, service virtualization and mocks, and walks through a docker-compose + pytest example that runs in CI.
Mocking vs stubbing for APIs, plus fakes, spies and service virtualization: what each test double does, when to use which, and worked examples with WireMock, MSW and Prism.
A 76-item API security testing checklist mapped to the OWASP API Security Top 10 (2023), with test ideas per risk, JWT and OAuth checks, rate limiting, data exposure and logging, and a downloadable CSV you can import into your test tracker.
A ready-to-use pack of 36 API pagination test cases for offset/limit, page/size, cursor and keyset pagination: boundaries, ordering stability, concurrent inserts, total counts and RFC 8288 Link headers, with pytest code and a free CSV.
A complete, fill-in API test plan template: scope, environments, entry and exit criteria, risk register, coverage targets, test data, tools, CI quality gates and reporting, plus a one-page API test strategy and a downloadable Markdown file.
22 concrete API testing examples grouped by type: functional, negative, auth, schema, pagination, rate limit, idempotency, performance smoke and security basics. Each has the request, the expected result and an assertion in REST Assured, pytest or a Postman test script.
How to gate AI-assisted development — why line coverage stops meaning anything, the four checks that hold, and where human review should be spent when volume outruns it.
What an API testing framework actually is, the three real categories to choose between, and a practical decision framework based on team language, CI/CD needs, and who should be able to read the tests.
