+# E2E Test Mocks
+
+This directory contains mock fixtures used in end-to-end tests for the jiti-tsc project.
+
+## Available Fixtures
+
+### `tsconfig-setup/`
+
+Basic TypeScript compilation fixture with simple path alias setup:
+
+- `@utils/*`: Maps to `./utils.ts`
+- Minimal setup for testing basic TSC functionality
+
+### `path-aliases-basic/`
+
+TypeScript with path aliases fixture:
+
+- `@/*`: Maps to `./src/*`
+- `@utils/*`: Maps to `./src/utils/*`
+- Demonstrates path alias resolution capabilities
+
+## Usage
+
+These fixtures provide two levels of TypeScript testing:
+
+1. **Basic TSC**: Use `tsconfig-setup/` for testing fundamental TypeScript compilation
+2. **TSC with Path Aliases**: Use `path-aliases-basic/` for testing path alias resolution
+
+Each fixture includes:
+
+- `tsconfig.json`: TypeScript configuration
+- Source files demonstrating the feature set
+- Test files for verification
+
+## Testing
+
+Use these mocks to test jiti-tsc's ability to handle TypeScript compilation with and without path aliases.

+# Path Aliases Basic Mock
+
+A simple mock fixture demonstrating basic TypeScript path aliases.
+
+## Path Aliases
+
+- `@/*`: Maps to `./src/*`
+- `@utils/*`: Maps to `./src/utils/*`
+
+## Files
+
+- `tsconfig.json`: TypeScript configuration with basic path mappings
+- `src/index.ts`: Main file using path aliases
+- `src/utils/math.ts`: Utility functions
+- `src/config.ts`: Configuration file
