AI Requirements Test Case Builder for fast browser-based work
Turn a feature requirement, user story, or AI implementation plan into acceptance tests, edge cases, negative cases, mobile checks, privacy checks, and a test-writing prompt.
中文：把功能需求、用户故事或 AI 实现计划变成验收测试、边界用例、负向用例、移动端检查、隐私检查和测试编写 prompt。
Example: Use it before asking a coding agent to implement a feature, after receiving an AI plan, or before shipping a new tool page.
Where this tool fits in real work
Use cases
- Paste a feature requirement, user story, or AI implementation plan before asking a coding agent to build it.
- Detect test dimensions such as input validation, privacy, mobile, reload state, copy/export, localization, and external services.
- Copy acceptance tests, edge cases, negative cases, and a prompt for an AI coding agent to implement or verify tests.
Review notes
- AI-generated implementation plans often cover the happy path and miss empty, long, malicious, mobile, or privacy cases.
- The tool creates a test plan and verification prompt; it does not generate or run code.
- Use it before feature work and again after AI proposes a solution.
Local-first handling
This page is built as a browser utility. Inputs are processed in the page where possible, with no account requirement and no intentional upload step for the tool workflow.
When to use AI Requirements Test Case Builder
Good fit

- Detect test dimensions such as input validation, privacy, mobile, reload state, copy/export, localization, and external services.
- Copy acceptance tests, edge cases, negative cases, and a prompt for an AI coding agent to implement or verify tests.
Before copying results
- AI-generated implementation plans often cover the happy path and miss empty, long, malicious, mobile, or privacy cases.
- The tool creates a test plan and verification prompt; it does not generate or run code.
- Use it before feature work and again after AI proposes a solution.
Use a stricter workflow
If the context includes production secrets, customer records, private research material, or executable scripts, redact first and use a stricter human review workflow.

AI Requirements Test Case Builder questions
Does it create automated test files?
No. It creates the test plan and a prompt you can give to a coding agent.
Why is this useful for AI work?
AI often implements the happy path first. A test-case plan forces empty, long, malicious, mobile, privacy, and reload scenarios into scope.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
