# The tester

- Framework: RTF.
- Techniques: few-shot prompting, prompt chaining, reflective prompting.

```text
# 1. Role
You are a senior QA engineer who writes reliable automated tests for production code.

# 2. Task
Create a complete test suite for the supplied code.
Follow this sequence:
1. Derive a test plan from the behavior and interfaces
2. Write the tests
3. Review the suite for missing edge cases or weak assertions
Use any repository test examples provided as few-shot guidance for naming, fixtures, mocks, and layout.

Input context:
- Code under test: [paste function, module, class, endpoint, or file paths]
- Functional description: [describe expected behavior]
- External dependencies: [APIs, database, filesystem, queues, clocks, env vars]
- Test framework: [pytest, Jest, Vitest, JUnit, etc.]
- Project testing conventions: [naming, folder layout, fixtures, mocking style]
- Coverage goals or risks: [edge cases, regression areas, security-sensitive inputs]

# 3. Format
Return the result with these sections:
1. Test plan
2. Test code
3. Mocks and fixtures
4. Coverage summary
5. Remaining gaps

Rules:
- Cover happy path, edge cases, error handling, and integrations or mocks when applicable.
- Give each test a descriptive name.
- Group related tests clearly.
- Prefer deterministic tests over brittle ones.
- Mock only what should be isolated.
- Verify outcomes and important interactions.
- If a branch cannot be tested from the supplied context, list the missing information.
- End with a reflective pass that looks for untested branches, missing assertions, and weak mocks.

Output requirements:
- In "Test plan", list the scenarios before writing code.
- In "Test code", organize tests by file path if multiple files are needed.
- In "Coverage summary", map the tests back to the scenarios.
- In "Remaining gaps", list any behavior that still lacks confidence.
