API Testing Guide
Ensure robust and reliable integration with WUPEX by implementing comprehensive API testing strategies. Below is a streamlined guide to testing best practices, workflows, and tools.
Set Up a Testing Environment
- https://sandbox-service.wupex.com
- Populate it with realistic but dummy data for thorough validation.
- Keep your testing and production environments logically separated (keys, domains, data).
Types of API Tests to Perform
- Unit Tests: Validate individual endpoint behavior with fixed inputs/outputs.
- Integration Tests: Test end-to-end flows such as ordering or balance checks.
- Security Tests: Verify API key handling, rate-limits, and unauthorized access.
- Edge Case/Fuzz Testing: Use invalid inputs, unexpected types, or boundary data.
- Performance/Limited Load Tests: Measure latency and behavior under load scenarios.
Recommended Tools
- Postman: Intuitive for manual and automated testing. Supports collections, environments, and CI integration.
- OpenAPI-based Automation: Auto-generate tests based on your API spec. Validate parameter combinations and structural consistency.
- Mock Services: Use tools like MockServer to simulate API dependencies or unavailable systems
Building a Test Plan
- Document Use Cases: Define flows — product listing, order placement, balance retrieval.
-
Design Test Cases:
Happy Path: Typical use (fetch, order, retrieve balance).
Negative Tests: Invalid SKUs, malformed JSON, missing headers. - Automate & Integrate: Embed tests in your CI/CD pipeline to validate with every deployment.
- Maintain Tests: Update tests with evolving API specs and support for new parameters.
Test Case Essentials
|
Test Type
|
Focus Area
|
|---|---|
|
Header Validation
|
Missing/invalid API key, improper locale headers
|
|
Payload Validation
|
Missing fields, invalid JSON, invalid types
|
|
Endpoint Coverage
|
Ensure all endpoints (products, orders, balance) are tested
|
|
Pagination & Filtering
|
Ensure page/size work, filters are applied
|
|
Error Scenarios
|
Test 401, 403, 404, 422, 429, 500, and back-off
|
|
Performance
|
Measure response times, load thresholds
|
Automating Tests
- Reusable Sub-Tests: Standard assertions (e.g., JSON structure, status codes) across endpoints
- Use Variables/Fixtures: Store keys, URLs, sample SKUs to avoid hardcoding in tests.
- Inspect Latency & Errors: Assert acceptable response times (< 500 ms) and handle failures cleanly.
Continuous Validation
- Run your API tests:
- On every code commit
- Prior to pushing to production environment
- After infrastructure upgrades or spec changes
- Clear failing tests fast to prevent broken integrations from reaching production.
Security & Quality Checks
- Verify unauthorized requests (401, 403) are handled securely.
- Ensure no sensitive data is returned in error messages.
- Abuse testing: Exceed rate limits to validate correct 429 behavior and back-off.
- Perform basic fuzzing to uncover vulnerabilities in parameter validation
Postman-Specific Recommendations
- Use Environments to separate sandbox and production settings.
- Create Collections for each endpoint group: products, orders, balance, errors.
- Add Tests scripts to validate JSON schema, response time, HTTP status.
- Configure Monitors/CI to run tests automatically and report issues.
Postman-Specific Recommendations
- A robust API testing strategy includes:
- Secure and isolated environment setup
- Comprehensive coverage: happy paths, edge cases, error scenarios
- Automation integrated with CI/CD pipelines
- Regular performance, security, and regression testing
- Embed this framework into your development workflow to ensure your WUPEX integration is resilient, secure, and high-quality.
