Nodejs execute exported function from string

I want to know if it's possible to run a function that is named a string in nodejs. All this code is running on the server side with no browser appearance at all.

Assuming I export a file test.js with the following code

module.exports.test = function(x)
{
   console.log(x*5);
}

Can I do this somehow?

main.js

imp = require('test.js');
toExecute = "test";

// somehow call imp.test using toExecute`
