Sure. Here you go:

qjson:

********* Start testing of tst_Json *********
Config: Using QTest library 4.7.2, Qt 4.7.2
PASS   : tst_Json::initTestCase()
RESULT : tst_Json::testByteArray():
     40,715,021.989 CPU ticks per iteration (total: 41,692,182,517,
iterations: 1024)
PASS   : tst_Json::testByteArray()
RESULT : tst_Json::testNumbers():
     559,103.889 CPU ticks per iteration (total: 572,522,383, iterations:
1024)
PASS   : tst_Json::testNumbers()
PASS   : tst_Json::cleanupTestCase()
Totals: 4 passed, 0 failed, 0 skipped
********* Finished testing of tst_Json *********

qjsonparser:


********* Start testing of tst_Json *********
Config: Using QTest library 5.0.0, Qt 5.0.0
PASS   : tst_Json::initTestCase()

qtbinaryjson:
