    Sample input

    User request: "I just refactored the discount logic in the Order service. Can you help me write proper tests?"

    Sample output

    Generated Output (excerpt):

    Test Strategy Summary

    Behavior Under Test The new discount calculation logic must correctly apply tier-based discounts, handle edge cases, and reject invalid inputs.

    Key Test Cases | Test Name | Purpose | Type | |----------------------------------------------|--------------------------------------|-------------| | should apply 15% Gold tier discount | Verify core business rule | Unit | | should reject negative quantity | Input validation | Unit | | should calculate correct tax for EU orders | Integration with tax service | Integration |

    Recommended Tests

    • 8 unit tests + 2 integration tests
    • Focus on boundary conditions and invalid states

    About This Skill

    Most AI-generated tests don’t actually protect your code

    Many developers use AI to generate tests that look comprehensive but only exercise happy paths, over-mock everything, or test internal implementation details instead of real behavior. These tests create a false sense of security and quickly become expensive technical debt.

    Test Generation & Verification with Grok gives you a professional-grade process for designing and writing tests that actually increase confidence when refactoring or shipping.

    What it does

    • Helps you define a clear testing strategy before writing any code
    • Focuses on high-impact edge cases and failure modes, not just happy paths
    • Generates tests that follow your project’s existing patterns and conventions
    • Balances different test types (unit, integration, contract, etc.) based on what needs protection
    • Includes verification steps so the tests remain reliable over time

    This skill is especially powerful when used together with Safe Code Changes with Grok ($7) and Skill Evaluation & Iteration with Grok ($5).

    Use Cases

    • Adding tests for new features or refactors
    • Increasing meaningful test coverage in legacy or poorly tested modules
    • Writing tests before making changes to complex logic
    • Fixing bugs using a “test first” approach
    • Preparing code for production or major releases

    This skill requires read and write access to source and test files plus the ability to execute test commands. It is intended for serious test engineering work rather than quick "generate some tests" requests.

    This skill is specifically optimized for **Grok** inside the **Grok Build CLI / TUI**.
