var assert = require('assert');

assert.notOk(isRegex(undefined));
assert.notOk(isRegex(null));
assert.notOk(isRegex(false));
assert.notOk(isRegex(true));
assert.notOk(isRegex(42));
assert.notOk(isRegex('foo'));
assert.notOk(isRegex(function () {}));
assert.notOk(isRegex([]));
assert.notOk(isRegex({}));

assert.ok(isRegex(/a/g));
assert.ok(isRegex(new RegExp('a', 'g')));
