Inside your while loop, use the .push() method to append input to the inputs array. This will help you get a better idea of how the conversion works later when you log the contents of your arrays to the console.
You should use the .push() method on the inputs array within your while loop.
assert.match(code, /while\s*\(\s*input\s*>\s*0\s*\)\s*\{[\s\S]*inputs\.push\(/);
You should use the .push() method to append input to the inputs array.
assert.match(String(decimalToBinary), /inputs\.push\(\s*input\s*\)\s*;?/);
