Covers the new com.codename1.testing.junit package from PR #5032: standard @test methods against the JavaSE simulator, with annotations for @RunOnEdt, @SimulatorProperty / @SimulatorProperties, and the visual-config set (@theme, @DarkMode, @LargerText, @orientation, @rtl). Calls out: - Simulator-only by design so tests get full JVM reflection (Mockito, AssertJ, etc.). - Annotations resolve method-over-class and are applied in a single batched setup on the EDT with one theme refresh. - junit-jupiter moves from test to provided scope so it does not leak onto the simulator's runtime classpath for non-opted-in apps. - AbstractTest / DeviceRunner stays for on-device and screenshot tests; the two frameworks are complementary.
