## Project history and usage

htmltest is a Go command-line checker for generated HTML sites. It tests links, images, scripts, alt text, and related generated-output problems, giving static-site and documentation projects a single binary alternative to heavier runtime stacks.

### Project history

The README introduces htmltest by comparing it with html-proofer: if a generated site needs checking but the user wants to avoid a Ruby environment or wants a faster standalone tool, htmltest is the Go-based option. The repository exposes `.htmltest.yml` configuration and release tags that show the project maturing through repeated 0.x releases.

The tag stream includes v0.8.1 in March 2018 and v0.17.0 in November 2022. A companion `htmltest-action` repository and GitHub Marketplace action show the project moving naturally into CI workflows where generated documentation and static sites are checked after builds.

### Adoption history

The input package facts record Homebrew, Nix, and Fedora development packaging. The official GitHub Action gives another adoption route: users can run the binary in CI without managing a local install, while package managers serve developers who want the same check available on laptops and build hosts.

### How it is used

htmltest is typically pointed at a generated output directory and optionally configured with `.htmltest.yml`. Its job is to catch broken internal or external references and markup hygiene issues before a static site, docs tree, or generated HTML artifact is published.

### Why package nerds care

For package nerds, htmltest is interesting because it packages a documentation QA pattern as a portable Go binary. It is not a browser and not a general validator; it is the small CI-friendly check that catches the boring broken-output mistakes before release.

### Timeline

- 2018: v0.8.1 was tagged in March.
- 2022: v0.17.0 was tagged in November.
- CI era: The companion `htmltest-action` repository documents running htmltest from GitHub Actions.
- Package-manager era: The input package facts record Homebrew, Fedora, and Nix packaging.

### Related projects

- htmltest is related to html-proofer, link checkers, static-site test steps, and GitHub Actions that validate generated documentation. Its practical neighbors are documentation build pipelines rather than browser-based HTML validators.
