Is there jsmock implementaion?

Can anybody point me to some jsmock implementation? My attempt to
google it failed

Google gives no results on "jsmock", so unless you tell us what such a
"jsmock" implementation should do, it's hard to say whether one exists
that satisfies your needs.

Oh, sorry for so unintelligible question. I've meant mock objects
implementation for javascript. Mock objects are used for isolating
tests in unit testing. (see e.g.
www.connextra.com/aboutUs/mockobjects.pdf)

While there might be a framework for helping with this somewhere,
Javascript objects are so easily customizable that it's probably not
necessary.

If you need an object that returns three different names from a call
to getName, you could just write:

{index : 0,
getName : function() {
return ["Tim","Tom","Jack"][this.index++];
}}

Since Javascript objects doesn't have a type, they don't have to go
through hoops to look like a specific type of objects. If need be,
they can havve their prototype chain set to emulate a specific
constructor.
---
function mock(constructor) {
function Dummy(){};
Dummy.prototype=constructor.prototype;
return new Dummy();
}
---
If you want to change the behavior of existing objects, you can
just clone them and add properties to the clone:
---
function clone(object) {
function Dummy(){};
Dummy.prototype = object;
return new Dummy();
}

var o = {foo:42, bar: "I said 42!"};
var oc = clone(o);
oc.foo = 37;

alert([o.foo, o.bar, oc.foo, oc.bar]);

Thank you for your answer.

But I seek for just framework that have usual (for nUnit users)
interface. I found only implementation. It is in Selenium test
framework. They are using it for _internal_ testing purposes. It isn't
an independent public project and implementation is very unpretentious.
It's important for me to have possibility write my tests in such a
manner:

collaborator = new Mock();
collaborator.expects("dispatch, "foo").returns(true);
collaborator.expects("dispatch, "bar").returns(true);

objectUnderTest = new MyClass(collaborator);
objectUnderTest .process("foo", "bar");

collaborator.verify();

If objectUnderTest will not call serially method dispatch with given
arguments the test will fail.

Selenium is accessible on
http://gforge.public.thoughtworks.org/download.php/51/selenium-0.6.0.zip

Mock implementation is in selenium-0.6.0\selenium\jsmock directory.
