run-in-docker.sh

#!/usr/bin/env bash

# Synopsis:
# Test runner for run.sh in a docker container
# Takes the same arguments as run.sh (EXCEPT THAT SOLUTION AND OUTPUT PATH ARE RELATIVE)
# Builds the Dockerfile
# Runs the docker image passing along the initial arguments

# Arguments:
# $1: exercise slug
# $2: **RELATIVE** path to solution folder (without trailing slash)
# $3: **RELATIVE** path to output directory (without trailing slash)

# Output:
# Writes the tests output to the output directory

# Example:
# ./run-in-docker.sh two-fer ./relative/path/to/two-fer/solution/folder/ ./relative/path/to/output-directory/
# ./run-in-docker.sh two-fer ./test/fixtures/two-fer/pass ./test/fixtures/two-fer/pass

# If arguments not provided, print usage and exit
if [ -z "$1" ] || [ -z "$2" ] || [ -z "$3" ]; then
    echo "usage: ./run-in-docker.sh two-fer ./relative/path/to/two-fer/solution/folder/ ./relative/path/to/output-directory/"
