# Taken from: https://rotational.io/blog/speeding-up-go-tests/ this python script assists in parsing Golang JSON unit

# tests and sorting them by the amount of time taken
|
|
#
|
|
# To use, run Go unit tests via the following:
|
|
# go test -v -json -count 1 github.com/cloudnativelabs/kube-router/v2/cmd/kube-router/ github.com/cloudnativelabs/kube-router/v2/pkg/... >testing_output.json
|
|
#
|
|
# Then run this script via:
|
|
# build/test-scripts/unit_test_timing.py testing_output.json
