Specifying a layout resource programmatically

As an alternative to using the TestifyLayout annotation, you may also specific a layout file to be loaded programmatically. You can pass a R.layout.* resource ID to setTargetLayoutId on the ScreenshotRule.

ScreenshotTestRule

class MainActivityScreenshotTest {

    @get:Rule var rule = ScreenshotRule(MainActivity::class.java)

    @ScreenshotInstrumentation
    @Test
    fun default() {
        rule
            .setTargetLayoutId(R.layout.view_client_details)
            .assertSame()
    }
}

ScreenshotScenarioRule

class MainActivityScreenshotTest {

    @get:Rule val rule = ScreenshotScenarioRule()

    @ScreenshotInstrumentation
    @Test
    fun default() {
        launchActivity<MainActivity>().use { scenario ->
            rule
                .withScenario(scenario)
                .setTargetLayoutId(R.layout.view_client_details)
                .assertSame()
        }
    }
}
