How to view/upload HTML files with coverage data through Travis?

[native-api]

You can

• cat them into the build log
  • There are tools that convert HTML to a similar-looking text which is more fit for console viewing, e.g. html2text, lynx and w3m; and/or
• upload them somewhere by hand with standard Linux tools or tools that you install
  • Specifically for coverage data, there are online services like https://coveralls.io/ that allow you to upload data from automated builds and view it there. See https://docs.travis-ci.com/user/coveralls/ ; or
• upload them somewhere with one of the stock deployers
