Thanks so much for your interest in Dash!

Before posting an issue here, please check the Dash community forum to see if the topic has already been discussed. The community forum is also great for implementation questions. When in doubt, please feel free to just post the issue here :)

Is your feature request related to a problem? Please describe.
This happens more than once among dash core developers that the local venv integration environment might be slightly different than the Circle CI Docker environment.

• mismatch of component version
• git commit sha is not the same, i.e. CircleCI docker contains the latest commit head from master, but locally might not always be the case
• mismatch of webdriver & browser version

Describe the solution you'd like
A simple script or command line tool to gather all the information mentioned above, so you can easily compare the mismatch from your local venv and circleci docker

Additional context
Part of the problem can be solved easily by using an adapted Dockerfile image based on CircleCI version, but for debugging purpose, locally venv is more flexible and convenient.
