This assertion should be removed because having just process.nextTick (no parens/uninvoked) is never going to throw, it will always return the function itself.

If you want to test the "same" thing as process.nextTick(), you could add testNextTickWith().

function () {
process.nextTick
}
);

function testNextTickWith(val) {
assert.throws(
function() {
process.nextTick(val);
},
TypeError
);
}

testNextTickWith(false);
testNextTickWith(true);
testNextTickWith(1);
testNextTickWith('str');
testNextTickWith({});
testNextTickWith([]);

process.on('uncaughtException', function() {
if (!exceptionHandled) {
exceptionHandled = true;
