Tests the assertion that "It is also possible to specify the scripting language for each individual ‘script’ element by specifying a ‘type’ on the ‘script’ element." by setting it to an unknown value and checking the script is not executed. The test uses an unknown (bogus) script language, which looks exactly like ECMAScript.
Load the test.
The test is passed if string "Good, script didn't run" is displayed. It fails if the string "No! This is not ECMAScript!" is displayed.
