Do you have any tutorial about exposing the object to be tested and referring a dependency

I just guess you made a great lib of qunit.  But cannot find any information about how to referring/requiring/my code to be tested and I also need to use sinon to mock something how can I include sinonjs in my testing?

I mean I know the testrunner has some thing like:

```
{
    code: "path/to/mycode",
}
```

but how can I get access to my vars, objects and dear sinon.
