* 1. Document node
* 2. In-document Element node
* 3. Detached Element node (an element with no parent, not in the document)
* 4. Document Fragment node
*
* For each context, the following tests are run:
*
* The interface check tests ensure that each type of node exposes the Selectors API methods.
*
* The matches() tests are run
* All the selectors tested for both the valid and invalid selector tests are found in selectors.js.
* See comments in that file for documentation of the format used.
*
* The level2-lib.js file contains all the common test functions for running each of the aforementioned tests
