What its author says it does

Copied from the file, not written here

Creates test plans and test cases (unit, integration, edge cases) based on existing or planned code

Test Generator

Purpose

Analyze existing or planned code and produce comprehensive test suites. Covers unit tests for individual functions, integration tests for module interactions, and edge case tests for boundary conditions. Detects the project's test framework automatically.

When to Use

New code has been written without tests
Existing code lacks coverage in critical paths
A bug was fixed and a regression test is needed
The user explicitly asks for tests

When Not to Use

The code is prototype or throwaway
The user asked for debugging, not testing
The testing strategy needs architectural design first

Inputs

Input	Type	Required	Description
`target`	string	Yes	File, module, or feature to test
`type`	enum	No (default: all)	unit, integration, edge-case, all
`framework`	string	No	Test framework (auto-detected if omitted)

Expected Outputs

Output	Description
Test files	New test files following project conventions
Coverage report	What's covered and what's not
Test run command	How to execute the tests

Exact Workflow Steps

Detect test framework from project config (Jest, Vitest, pytest, etc.)
Read the target code and identify all exported functions, classes, and behaviors
For each function: test happy path, error cases, edge cases (empty input, null, boundaries)
Create test file following existing test conventions (naming, location, patterns)
Mock external dependencies (APIs, databases, file system)
Run tests to confirm they pass

Required Checks

All tests pass
Edge cases are covered (not just happy path)
Mocks are used for external dependencies
Tests are deterministic (no flaky tests)

Failure Modes

Failure Condition	Response
Test framework not detectable	Ask user to specify framework
Tests fail due to code bugs	Report failing tests and suggest fixes
Mock is too complex	Suggest integration test instead of mocked unit test
