   0. Create sample BuildConfigs using the Docker and Source build strategies, and start a build. 
   1. Follow instructions on https://docs.openshift.com/container-platform/4.12/cicd/builds/securing-builds-by-strategy.html#builds-disabling-build-strategy-globally_securing-builds-by-strategy end to end, for the Docker and Source strategy.
    2. Try to create a Docker, Source, or Custom strategy BuildConfig
    3. Try to start a build for the respective strategy
    4. Try to create a Custom strategy build as a regular developer/edit user
    

    Developers can create Custom strategy builds. Source strategy build is not disabled.
    

    Source and Docker strategy builds are disabled globally. Customers can't create or start builds with these strategies.
