Wraps and executes the passed function into try-catch

1-try-catch.js

function tryCatch (/* fn, context, arguments */) {
  var args = Array.prototype.slice.call(arguments);
  var fn = args[0];
  var context = args[1];

  args = args.slice(2, args.length);

  try {
    fn.apply(context, args);
  } catch (e) {
  }
}

2-sinon-example.js

function error(e) {
  throw e;
}

error = sinon.spy(error);

tryCatch(error, null, new Error('Exception was thrown'));

expect(error)
  .to.have.been.calledOnce
  .and
  .have.been.calledWithMatch({ message: 'Exception was thrown', name: 'Error' })
  .and
  .have.thrown();
