 #### The CGI
+
 - Based on the file extension the server will execute the corresponding `CGI` (for example `.php` or `.py`).
 - You need to implement only one `CGI` of your choice.
 - You are allowed to fork a new process to run the `CGI`.
 - `CGI` expects the file to process as first argument and `EOF` as end of the body.
 - Pay attention to the directory where the `CGI` will run for correct relative paths handling.
 - The `CGI` will check `PATH_INFO` environment variable to define the full path.

 #### Testing your server

 - Do stress tests with `siege -b [IP]:[PORT]`, it must stay available at all costs (availability should be up to 99.5, it will be tested during audits).
 - Create tests for as many cases as you can (redirections, bad configuration files, static and dynamic pages, default error pages and so on).
 - You will be requested to provide and explain your tests during the audits.

+### Unit Tests
+
+You must implement unit tests within your `Localhost` project to ensure your protocol parsing and configuration logic are robust. Specifically, your tests should:
+
+- Verify **HTTP Request Parsing** by ensuring headers, methods (GET, POST, DELETE), and body content (including chunked encoding) are correctly extracted from raw byte streams.
+- Verify **Configuration Validation** by ensuring the server correctly identifies conflicting ports, invalid paths, and out-of-bounds body size limits during startup.
+- Test **Route Matching** logic to confirm that requests are mapped to the correct directory roots, CGI scripts, or redirections based on the configuration file.
+- Verify **Status Code Generation** by ensuring the internal logic returns the correct `4xx` or `5xx` codes for malformed requests or missing files before the response is sent.
+
 ### Bonus
+
 - Handle at least one more `CGI`.
 - Rewrite the project in another programming language (can be `C++` or `C`).
