| 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. Build lancelot baselineserver. |
| - cd [your qt5 path]\qtbase\tests\baselineserver\src\ |
| - qmake |
| - jom (or make or nmake) |
| |
| 2. Start lancelot baselineserver and leave it running. |
| - cd [your qt5 path]\qtbase\tests\baselineserver\bin\ |
| - baselineserver.exe |
| |
| 3. With Qt Creator, open Quick3D lancelot tests project |
| (qtquick3d\tests\auto\quick3d_lancelot\quick3d_lancelot.pro) |
| |
| 4. In Creator Project Settings, set an environmental variable |
| "QT_LANCELOT_SERVER" to "127.0.0.1". |
| |
| 5. Run quick3d_lancelot 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 quick3d_lancelot 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 |
| ********* Finished testing of tst_Quick3D ********* |
