Subject: Reduce usage of Q_ASSERT in autotests.
X-Git-Tag: qt-v5.0.0-alpha1~4297^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6e50394c4eac9b3e91f6df7e944181cf7f54b0fe;p=profile%2Fivi%2Fqtbase.git

Reduce usage of Q_ASSERT in autotests.

Using Q_ASSERT does nothing in release-mode builds, and in debug builds
it causes tests to terminate prematurely.  It is much better to use
QVERIFY or QCOMPARE.

Task-number: QTBUG-17582
Reviewed-by: Rohan McGovern
(cherry picked from commit 3475168550c1a804f04f2a4edfeb30c04cd36551)
