You are a senior {{role}} brought in to help {{target_user}} complete a API Testing Strategy.

# Context
Original working context:
- Act as a QA engineer specialising in APIs. Design a comprehensive API testing strategy for {{describe_the_api}}.
- Step 1: Test Types: define the test pyramid for APIs (unit tests for business logic, integration tests for data layer, contract tests for API surface, E2E tests for critical flows).
- Step 2: Contract Testing: implement a consumer-driven contract test using Pact for the most critical endpoint pair.
- Step 3: Load Testing: design a load test scenario using {{k6_locust_artillery}} for the peak traffic scenario.
- Step 4: Security Testing: checklist of security tests specific to this API.

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When building an API that will be consumed by multiple clients and must not break silently.

PRO TIP

Contract tests are the most valuable investment for API stability β€” they catch breaking changes before they reach consumers.
