# Usage: $ ./are-we-synapse-yet.py [-v] results.tap
# This script scans a results.tap file from Dendrite's CI process and spits out
# a rating of how close we are to Synapse parity, based purely on SyTests.
# The main complexity is grouping tests sensibly into features like 'Registration'
# and 'Federation'. Then it just checks the ones which are passing and calculates
# percentages for each group. Produces results like:
# 
# Client-Server APIs: 29% (196/666 tests)
# -------------------
#   Registration             :  62% (20/32 tests)
#   Login                    :   7% (1/15 tests)
#   V1 CS APIs               :  10% (3/30 tests)
#   ...
#
# or in verbose mode:
#
# Client-Server APIs: 29% (196/666 tests)
# -------------------
#  Registration             :  62% (20/32 tests)
#    ✓ GET /register yields a set of flows
#    ✓ POST /register can create a user
#    ✓ POST /register downcases capitals in usernames
#    ...
# 
# You can also tack `-v` on to see exactly which tests each category falls under.
