#!/bin/bash
#
# Run end-to-end Saha interpreter tests with coverage collection enabled.
#
# First, install kcov (above version 35) to an accessable location. Then run
# this either by relying on your $PATH to find kcov:
#
#     $ ./coverage-test.sh
#
# Or supply a path to your kcov binary manually:
#
#     $ ./coverage-test.sh /path/to/kcov
#
# The script runs the tests and dumps coverage data to `./target/coverage` in
# kcov format (HTML and cobertura).
#
# This script has been tested with a Debian-like Linux, but might work
# on other systems as well.
