just a simple test runner

test.js

function logError(description, result, expectation) {
  console.error('✖ ', description)
  console.log('expected: ', expectation)
  console.log('got: ', result)
}

function test(description, assertion, expectation) {
  const result = assertion();
  result === expectation
  ? console.log('✔ ', description)
  : (() => {
    logError(description, result, expectation);
    console.trace();
  })();
}

exports.test = test;
