38 * Testing a HiDPI display is difficult without running in a HiDPI display.
39 * The gathering of screen size and resolution performed by jalview.bin.HiDPISetting
40 * is now farmed out into a separate class jalview.bin.ScreenInfo so it can be more
41 * easily Mocked in tests.
42 * Two sets of tests are performed.
43 * 1) testLinuxScalePropertyToActualTransform() sets the property that HiDPISetting
44 * uses (via jalview.bin.Launcher or getdown) to scale up Jalview, and then looks at
45 * the alignment panel graphics2d transform to see if it's been scaled by the same
46 * amount (in this case 4 -- unlikely to happen by accident!).
47 * 2) testHiDPISettingInit() which tests the calculation that HiDPISetting uses to
48 * decide from apparent screen information (mocked using Mockito in the tests) what
49 * scaling factor to set (it doesn't actually set it, just suggests it to
50 * jalview.bin.Launcher)
