The syntax for the npm test script is invalid on windows, and therefore cannot run. There needs to be a different means of referencing the jasmine-node package in
"test": "npm run eslint && npm run compile && node_modules/.bin/jasmine-node build/spec/tests"
since windows is not smart enough to look for the exe or script via the relative path. You will get an error that reads
'node_modules' is not recognized as an internal or external command
Wrapping the command in double quotes fixes the issue on windows.
"node_modules/.bin/jasmine-node" build/spec/tests
