Loading this page executes some simple automated javascript tests of the Sling client library.
Note that, in Sling revision 669215, the tests fail unless the Allow Anonymous Access parameter of the Sling Request Authenticator component is set to false, see SLING-322.
If all goes well, the paragraph styled like this below should say "Done running tests".
Tests run quickly, this might have happened already.
To run the tests again click here.
After running the tests at least once, /sling-test/testhtml-nodes.json should show the JSON data of the nodes created by the test cases.
See the source code of this page for details.
