tc = new SimpleDrawingTestCase() ;
tc.runTest("testDrawSimpleRangePlusOne")
(execution method #1, by string)
tc.runTest(tc.testDrawSimpleRangePlusOne)
(execution method #2, by function reference)
Alternatively you can use query args:
local.html?testCase=ScrollingDivTestCase&test=testNestedDiv_Scrolled&command=runTest
