- * `@UiThreadTest` is a simple way to run an entire test body on the main thread. But if a test
- * executes code that appends message(s) to the main thread's `MessageQueue`, the annotation will
- * prevent those messages from being processed until after the test body finishes.
+ * `@UiThreadTest` is incompatible with this rule. The annotation causes this rule to run on the
+ * main thread, but it needs to be run on the test thread for it to work properly. Instead, only run
+ * code that requires the main thread using something like [Instrumentation.runOnMainSync] or
+ * [TestUtil.getOnUiThread].
  *
- * To test pending messages, instead use something like [Instrumentation.runOnMainSync] to perform
- * only sections of the test body on the main thread synchronously:
  * ```
  * @Test
  * fun example() {
