+/**
+ * This test checks the Secure Context state of documents for various
+ * permutations of document URI types and loading methods.
+ *
+ * The hierarchy that is tested is:
+ *
+ *   creator-doc > createe-doc
+ *
+ * The creator-doc is one of:
+ *
+ *   http:
+ *   https:
+ *
+ * The createe-doc is loaded as either a:
+ *
+ *   popup
+ *   iframe
+ *   sandboxed-iframe
+ *
+ * into which we load and test:
+ *
+ *   http:
+ *   https:
+ *   blob:
+ *   javascript:
+ *   about:blank
+ *   initial about:blank
+ *   srcdoc
+ *
+ * TODO once web-platform-tests supports it:
+ *   - test http://localhost
+ *   - test file:
+ *
+ * TODO once https://github.com/w3c/webappsec-secure-contexts/issues/26 is resolved
+ *   - test data:
