#!/usr/bin/env bash

# Synopsis:
# Run the test runner on a solution.

# Arguments:
# $1: exercise slug
# $2: absolute path to solution folder
# $3: absolute path to output directory

# Output:
# Writes the test results to a results.json file in the passed-in output directory.
# The test results are formatted according to the specifications at https://github.com/exercism/docs/blob/main/building/tooling/test-runners/interface.md

# Example:
# ./bin/run.sh two-fer /absolute/path/to/two-fer/solution/folder/ /absolute/path/to/output/directory/

# If any required arguments is missing, print the usage and exit
if [ -z "$1" ] || [ -z "$2" ] || [ -z "$3" ]; then
    echo "usage: ./bin/run.sh exercise-slug /absolute/path/to/two-fer/solution/folder/ /absolute/path/to/output/directory/"
    exit 1
