In the Install development tools and Ros tools section link it looks like the pytest dependencies are needed only on Ubuntu 16.04. I’m on Ubuntu 18.04 and without them the build process prompted a lot of warnings about pytest missing and then failed while building the demos package.

Would you mind opening an issue on the source repository for that documentation. I’ve tested the instructions and most of the pytest related packages are pulled in as dependencies of colcon on 18.04. Thanks
