From 7bb8e9b9b24141f373ed70d7e6674a245c0227cf Mon Sep 17 00:00:00 2001 From: "thomasvl@gmail.com" Date: Mon, 22 Sep 2008 23:33:44 +0000 Subject: - Added GTMTestTimer.h for doing high fidelity timings. - Added leaks checking to iPhone unit test script. It can be controlled by the GTM_DISABLE_LEAKS environment variable - Added ability to control using zombies to iPhone unit test script. It can be controlled by the GTM_DISABLE_ZOMBIES environment variable - Added ability to control termination to iPhone unit test script. It can be controlled by the GTM_DISABLE_TERMINATION environment variable - Fixed several leaks found with leak checking enabled. - Added configs for different iPhone OS versions. --- UnitTesting/GTMTestTimerTest.m | 56 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 UnitTesting/GTMTestTimerTest.m (limited to 'UnitTesting/GTMTestTimerTest.m') diff --git a/UnitTesting/GTMTestTimerTest.m b/UnitTesting/GTMTestTimerTest.m new file mode 100644 index 0000000..86f9d22 --- /dev/null +++ b/UnitTesting/GTMTestTimerTest.m @@ -0,0 +1,56 @@ +// +// GTMTestTimerTest.m +// +// Copyright 2008 Google Inc. +// +// Licensed under the Apache License, Version 2.0 (the "License"); you may not +// use this file except in compliance with the License.
