 The `Dockerfile` defines two testing environments:

 - **debian-test**: Based on Debian 12
 
 Each environment:

 1. Installs minimal dependencies (curl, git, sudo, wget)
 2. Creates a test user with sudo permissions
 3. Sets up the directory structure for testing

 ### Key Differences
 
 **Standard Tests** (`ubuntu`, `debian`):
+
 - Use the Docker targets defined in the main Dockerfile
 - Run the `test-setup.sh` script to check components
 - Faster execution, focused on component validation
 - Don't perform the actual bootstrap installation
 
 **Full Tests** (`full-ubuntu`, `full-debian`):
+
 - Create a temporary Dockerfile for comprehensive testing
 - Execute the bootstrap script directly from GitHub
 - Complete end-to-end testing of the actual installation process

 ## Adding New Tests
 
 To add new package tests:
+
 1. Add the package name to `setup/packages.list`
 2. The test framework will automatically validate its availability and installation
 
 For more complex components:
+
 1. Add a new test function in `test-setup.sh`
 2. Call the function in the main testing sequence
 3. Increment the error counter if the test fails
