# TL;DR - For public repositories the safest approach will be to use the default read permissions, but at the cost
# of not being able to modify the labels. That will need to be a separate [trusted] workflow that runs from the base repo
# permissions :
#   contents : read
#   pull-requests : write
  
# Write our tests out this way for easier legibility
# testsSet    :
#   - key : value
#     key : value
#     tests :
#       - value
#       - value
#   - < next test >
