run-test.sh

#!/usr/bin/env bash

# runs a bash script test under MSYS2 (e.g. git bash) environment in an isolated directory.
#
# A test is named *.test.sh and passed as argument to this script.
# Since the test will run in an isolated directory (chroot), you
# might have to setup additional files that your test needs. E.g.
# another script that should be tested. Do do that place a script named
# *.before.sh beside your test script. The before script will be called
# with the root of the isolated test directory as it's first argument.
#
# E.g.
# some.sh
# -------
# echo "some test"
# =======
#
# some.test.sh
# -------
# OUTPUT=$(./some.sh)
#
# if [ "${OUTPUT}" != "some test" ]; then
#    echo "Expected output should be 'some test', but was '${OUTPUT}'"
#    exit 1
#fi
# =======
# some.before.sh
# -------
# cp some.sh $1
# =======
# run-test.sh some.test.sh
