Why not just use assert.throws()?

I just quickly duplicated the section above. I'm open to suggestions here.

IMO it would make more sense to use assert.throws() with a validation function like:

function(err) {
  return err instanceof Error && err.message === '`value` required in setHeader("foo", value).';
}

Truth be told, I think the try/catch is more readable.

@brendanashworth go for it.

res.setHeader('foo', undefined);
} catch (e) {
assert.ok(e instanceof Error);
assert.equal(e.message, '`value` required in setHeader("foo", value).');
threw = true;
}
assert.ok(threw, 'Undefined value should throw');

res.writeHead(200, { Test: '2' });
res.end();
});
