ocov

The ocov tool, short for OPA Coverage Report, colors into green and red the covered / not covered lines of the Rego policies, as output by opa test --coverage.

Build

git clone --recursive https://github.com/c5t/ocov.git
cd ocov
NDEBUG=1 make .current/ocov

Install

Copy .current/ocov somewhere into your $PATH. The following command does the job on both Mac and Linux.

sudo cp .current/ocov /usr/local/bin/

Use

Either:

opa test ${TEST_ARGS} --coverage | ocov

Or:

opa test ${TEST_ARGS} --coverage > coverage.json
ocov --input coverage.json

There are also:
