+   * 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
