Why Learn Here Practice-first labs using Postman, Newman, Python, JavaScript, and REST Assured Integration testing course path with microservices, Docker, CI/CD, and performance testing basics Career-ready portfolio and preparation for QA certification Measure what matters: track API test coverage with and use data to improve reliability. In God we trust; all others must bring data. W. Edwards Deming Statistician and Quality Pioneer What You Will Practice In These API & Integration Testing Courses Designing test strategies for REST and GraphQL. Writing API automation testing with assertions and data-driven tests. Contract testing for services with Pact or OpenAPI schemas. Mocking, stubbing, and test data management. Integration testing across microservices and CI pipelines. Outcomes You Can Expect SkillOutcome REST API testingConfidently validate endpoints and error handling Integration testingCatch regressions between services before release API automationReusable test suites integrated into CI/CD Try this sample endpoint: GET https://api.example.com/v1/users?limit=10 import requests def test_users_endpoint(): r = requests.get("https://api.example.com/v1/users", params={"limit": 10}, timeout=10) assert r.status_code == 200 data = r.json() assert isinstance(data, list) assert len(data) <= 10 # Contract-style checks for u in data: assert set(["id", "name", "email"]).issubset(u.keys())Are your services truly integration‑ready? Prove it with contract tests and CI checks before customers do. Avoid These Pitfalls: flaky tests from shared state, ignoring rate limits, brittle assertions on transient fields, skipping negative cases, and missing schema validation. You are an expert QA engineer. Given an OpenAPI or GraphQL schema (URL or JSON) and a base URL, produce: 1) a prioritized API test plan (happy path, error path, edge cases); 2) JSON Schema or SDL validations; 3) idempotency, pagination, and rate-limit checks; 4) security tests (auth, RBAC, injection, headers); 5) runnable Postman/Newman or pytest snippets; 6) CI steps to run on pull requests with pass/fail gates and artifacts.
