Passing Intent extras to the Activity under test

Some activities may require a Bundle of additional information called extras. Extras can be used to provide extended information to the component. For example, if we have a action to send an e-mail message, we could also include extra pieces of data here to supply a subject, body, etc. To provide extras to your Activity, you can implement the addIntentExtras method on ScreenshotRule and pass a lambda that can add to the provided Bundle.

If you are using ScreenshotScenarioRule, you should use the built-in Intent support provided by ActivityScenarioRule.

ScreenshotTestRule

class MainActivityScreenshotTest {

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

    @ScreenshotInstrumentation
    @Test
    fun default() {
        rule
            .addIntentExtras {
                it.putString("TOOLBAR_TITLE", "addIntentExtras")
            }
            .assertSame()
    }
}

ScreenshotScenarioRule

class MainActivityScreenshotTest {

    @get:Rule val rule = ScreenshotScenarioRule()

    @ScreenshotInstrumentation
    @Test
    fun default() {

        val context = InstrumentationRegistry.getInstrumentation().targetContext
        val intent = Intent(context, MainActivity::class.java).apply {
            putExtra("TOOLBAR_TITLE", "addIntentExtras")
        }

        launchActivity<MainActivity>(intent).use { scenario ->
            rule
                .withScenario(scenario)
                .assertSame()
        }

    }
}
