Bug description copied from that link: "QtTest's compare() function considers two colors (the QML basic type) as equal when they aren't. I am aware that Qt.colorEqual exists (and it works correctly), but I think that this makes it far too easy to write tests that don't catch an error. Consider the following test case: import QtQuick 2.2 import QtTest 1.0 Item { Rectangle { id: black color: "#000000" } Rectangle { id: white color: "#ffffff" } TestCase { name: "ColorComparison" function test_this_should_fail() { compare(black.color, white.color) } function test_this_is_ok() { compare(black.color == white.color, false) compare(Qt.colorEqual(black.color, white.color), false) } } }" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtdeclarative-opensource-src/+bug/1610349/+subscriptions -- Mailing list: https://launchpad.net/~ubuntu-sdk-bugs Post to : ubuntu-sdk-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-sdk-bugs More help : https://help.launchpad.net/ListHelp
