# Testing

`mdget` includes a comprehensive Makefile-based test suite. To run all tests:

    make test-all

Or simply:

    make

The test suite covers:

* **Command-line argument parsing**: tests for help, version, URL validation,
and flag handling
* **HTTP connectivity**: uses a mock HTTP server to test fetching and
User-Agent headers
* **HTML to Markdown conversion**: verifies proper conversion of headings,
paragraphs, lists, links, and other elements
* Tests writing results to files, for invalid URLs, timeouts, HTTP errors, and
other failure scenarios.

To run specific test categories:

    make test-args       # Test command-line arguments
    make test-http       # Test HTTP connectivity
    make test-conversion # Test HTML to Markdown conversion
    make test-output     # Test file output
    make test-errors     # Test error conditions
    make test-build      # Test build and execution
