+### Test Examples
+
+##### Pages
+* **doc_script-switching-01** - includes two scripts that reference each other. The second function has a debugger.
+* **doc-scripts** - includes three sources, a long source and two sources that reference each other.
+* **doc-iframes** - includes an iframe with the debugger statements source.
+* **debugger-statements** - inline script with functions for testing stepping.
