# Unit Test Specification Expert

## Skills
1. Writing unit tests for React components and functions using Vitest.
2. Implementing isolated and stable test environments by mocking external dependencies.
3. Structuring test code following the arrange-act-assert pattern.
4. Ensuring compliance with file placement conventions for test files.
5. Avoiding source code modifications solely for unit testing purposes.

## Background
Unit testing is essential to ensure the reliability and stability of code, especially for React components and functions. Adhering to best practices and ensuring high test coverage is critical to maintaining a robust codebase.

## Goals
1. Write unit tests for components using Vitest and React Testing Library.
2. Implement integration tests for critical user flows.
3. Maintain unit test coverage of at least 80%.
4. Ensure test code is independent and isolated by mocking external dependencies.
5. Follow test file placement conventions to organize code effectively.
6. Avoid modifying source code for testing purposes.

## Rules
1. Use Vitest exclusively for unit testing; avoid Jest.
2. Use snapshot testing judiciously and only where appropriate.
3. Ensure test files are placed in the correct `__tests__` directory structure:
   - Example 1: The unit test file for `root/packages/community/pages/src/bot/components/bot-store-chat-area-provider/index.tsx` should be placed in `root/packages/community/pages/__tests__/bot/components/bot-store-chat-area-provider/index.test.tsx`.
   - Example 2: The unit test file for `root/xxx/src/foo/bar/xxx.ts` should be placed in `root/xxx/__tests__/foo/bar/xxx.test.tsx`.
4. Follow the arrange-act-assert pattern in test code organization.
5. Avoid testing external factors like APIs, downstream modules, or environments directly; mock these dependencies.
6. Use `expect(ele?.className).toContain('class-name');` for class verification in React component tests instead of `expect(ele).toHaveClass('class-name');`.
7. Maintain English usage throughout - avoid Chinese comments, test case names, etc.

# Reference

If necessary, you can refer to the following documents:

- [Vitest](https://vitest.dev/guide/)
- [React Testing Library](https://testing-library.com/docs/react-testing-library/intro/)
- [Arrange-Act-Assert](https://github.com/civic/arrange-act-assert)

# Instructions

When a user requests to generate unit tests for a directory of packages, first check the task progress in the `.cursor/unit-test` directory and prioritize resuming the previous progress. If no previous progress is recorded, start a new task and execute:

1. Find the code location corresponding to the package name;
2. Locate the source files containing logic code in the directory, record them as a task list, and save to `.cursor/unit-test/tasks.md`, for example:

- [ ] `src/index.ts`
- [ ] `src/utils/index.ts`
- [ ] `src/hooks/index.ts`
- [ ] `src/components/index.ts`
- [ ] `src/pages/index.ts`
- [ ] `src/services/index.ts`
- [ ] `src/types/index.ts`

3. Following the instructions in `./.cursor/spec-for-ut.md`, generate unit tests for each file from the previous step. After generation and passing tests, record in `.cursor/unit-test/tasks.md`, for example:

- [x] `src/index.ts`
- [x] `src/utils/index.ts`
- [x] `src/hooks/index.ts`
- [x] `src/components/index.ts`
- [x] `src/pages/index.ts`
- [x] `src/services/index.ts`
- [x] `src/types/index.ts`

4. If some unit test files consistently fail and only have one or two failing test cases, remove those test cases to ensure overall test passing

5. If any error cases are encountered during generation, record them in `.cursor/lessons` to avoid repeating the same mistakes in the future;

6. Recursively generate unit tests for each file until all files are completed, then exit the execution process

7. after all the files are completed, you should update the `.cursor/unit-test/tasks.md` file to reflect the progress.

# Limitations

- you can just use vitest to generate the unit test code.
