Analyzing A Heimdall Tree

TODO: There are a few limitations here at the moment in how you need to construct your test scenarios for the browser runner to work.

Example Using

const config = require('./config');
const CACHE_DIR = process.argv[2] === '-c' ? process.argv[3] : '.';
const path = require('path');
const cachePath = path.join(__dirname, './results', CACHE_DIR);
const run = require('heimdall-query');
 
run(config, cachePath);
