++ The Lancelot system is an extension of the QTest unit test framework.
++ Its purpose is to help catch rendering regressions. It facilitates
++ rendering a suite of test scenes, and comparing the produced output
++ images with the images produced from a previous rendering run.
++
++ Here are instructions for running lancelot tests locally on your PC:
++
++ 1. Install baselineserver :
++ - clone git.qt.io:playground/lancelot.git
++ - check [lancelot]/baselineserver/install/install.txt for installation guide
++
++ 2. Start lancelot baselineserver and leave it running.
++
++ 3. Build QtQuick3D with QT_BUILD_TESTS flag ON
++
++ 4. In Creator Project Settings, set an environmental variable
++ "QT_LANCELOT_SERVER" to "127.0.0.1".
++
++ 5. Run tst_Quick3D for the first time and you should see many
++ "Baseline not found on server. New baseline uploaded." lines.
++ Baseline PNG images will be stored into path like:
++ C:\var\www\Other\tst_Quick3D\baselines\testRendering\
++
++ 6. Apply your changes, fixes etc. and run tst_Quick3D test again.
++ If rendering output doesn't change to better or worse, you should see
++ something like:
++ ...
++ PASS : tst_Quick3D::testRendering(view3d/RenderModeOverlay.qml)
++ PASS : tst_Quick3D::testRendering(view3d/RenderModeRenderNode.qml)
++ PASS : tst_Quick3D::testRendering(view3d/RenderModeTexture.qml)
++ PASS : tst_Quick3D::testRendering(view3d/RenderModeUnderlay.qml)
++ PASS : tst_Quick3D::cleanupTestCase()
++ Totals: 80 passed, 0 failed, 0 skipped, 0 blacklisted, 122662ms
