Where can I find comprehensive documentation on Google Test?
Shameless plug: Because it's annoying to go through the unrendered md files locally and use the difficult to navigate around md files on github, I publish the google test docs (https://gunslingerfry.github.io/google-test-docs) using mkdocs with a very minimal addition of an index.
The documentation is in the GitHub repo, as .md files in the googletest/docs directory. Start with Primer.md. And then you can look at more advanced topics.
