Testing Documentation Before Publishing
Documentation testing is following your own instructions on a machine where your project isn't already set up. If you test on the same machine you wrote the docs on, you'll miss every gap that your existing environment fills silently.
The Fresh Environment Test
Before publishing any tutorial or guide: create a new directory, start from the stated prerequisites, and follow every step exactly as written. Do not skip. Do not improvise. Every step you can't follow is a doc failure.
Automated Checks
# Check for broken links
npm install -g markdown-link-check
markdown-link-check ./docs/**/*.md
# Lint Markdown formatting
npm install -g markdownlint-cli
markdownlint docs/Code Block Validation
For docs with code examples, set up CI to extract and execute code blocks. Tools like doctest in Python and mdx-js plugins can run code in your docs as part of your test suite. Broken code examples in published docs are a support liability.
Reader Feedback Integration
Add a feedback mechanism to every doc page — even a simple "Was this helpful? Yes / No" with a GitHub issue link. The first 10 readers of a new doc will find every remaining gap. Capture that signal immediately.
