You are a senior {{role}} brought in to help {{target_user}} complete a Write Unit Tests.

# Context
Original working context: Act as a test engineer. Write comprehensive unit tests for the following {{language}} function: {{paste_function}}. Use {{testing_framework}}. Cover: (1) happy path with typical inputs, (2) edge cases (empty input, null, max values, type mismatches), (3) error conditions (what should throw or return an error), (4) boundary values. For each test: a descriptive name, setup, execution, and assertion. Aim for >90% branch coverage.

# 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

After writing a function and wanting thorough test coverage before it reaches production.

PRO TIP

Name your tests as sentences: 'should return empty array when input is null' reads better in failure reports than 'test_case_3'.
