Taking a screenshot of an area less than that of the entire Activity
It is often desirable to capture only a portion of your screen or to capture a single View.
For these cases, you can use the setScreenshotViewProvider on ScreenshotRule to specify which View to capture.
Using ScreenshotRule.setScreenshotViewProvider, you must return a View reference which will be used by Testify to narrow the bitmap to only that View.
    @TestifyLayout(R.layout.view_client_details)
    @ScreenshotInstrumentation
    @Test
    fun default() {
        rule
            .setScreenshotViewProvider {
                it.findViewById(R.id.info_card)
            }
            .assertSame()
    }
