Sometimes we will get flaky test failures in Espresso when running code like the following:

composeTestRule.waitUntilExactlyOneExists(hasTestTag("someTag")).assertIsDisplayed()

Similarly, we will also see flaky failures when trying to click on a node:

composeTestRule.waitUntilExactlyOneExists(hasTestTag("someTag")).performClick()

The performClick call will execute, yet nothing will happen.

Adding manual calls to android.os.SystemClock.sleep(), and/or using a while loop to repeatedly run assertIsDisplayed addresses the issues for us but I believe there should be a public API for this.
