Pragmatic Tips

Speed up your builds

Build your own image running tox --notest with your tox.ini file, push it to your (private) registry, and use that image for your builds. When your builds run, any missing -- and only those! -- dependencies are installed. Your builds will be lightning-fast and still reliable!
