Each test in RegionBackgroundImageUITest makes several calls to `robot.getPixelColor()` on App thread. Due to this each test requires more than **60** seconds for execution.
Fix is to save a screen capture of Scene (on App thread) and then read pixel color from the screen capture(not on app thread). This reduces execution time of each test to less than **3** seconds. Ideally with this fix(commit#1) all the tests should pass. All tests do pass on Windows and Linux but three tests fail on Mac, which used to pass without this change. - RegionBackgroundImageUITest.unalignedImage - RegionBackgroundFillUITest.testScenario2 - RegionBackgroundFillUITest.testScenario3 commit#2 solves the above problem. Solution is to fallback to test color again by reading it using `robot.getPixelColor()` on App thread when a test fails. One test RegionBackgroundImageUITest.unalignedImage_Cover, fails only on Mac platform, before and after this fix. It is reported as a new issue [JDK-8255679](https://bugs.openjdk.java.net/browse/JDK-8255679) This is a test fix and affects only the tests that extend from `RegionUITestBase` test class and does not affect other tests. Verified that `RegionBackgroundImageUITest` and `RegionBackgroundFillUITest` tests pass on all three platforms(except RegionBackgroundImageUITest.unalignedImage_Cover which fails on Mac). ------------- Commit messages: - fix for tests failing on Mac - ideal fix, but causes 3 test fail Changes: https://git.openjdk.java.net/jfx/pull/344/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=344&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8088739 Stats: 33 lines in 3 files changed: 28 ins; 3 del; 2 mod Patch: https://git.openjdk.java.net/jfx/pull/344.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/344/head:pull/344 PR: https://git.openjdk.java.net/jfx/pull/344
