7. writeTo(R.id.editTextId, “Cooooool stuff!”) clearText(R.id.editTextId)
8. Are you having troubles to test ListViews / RecyclerViews?
9. clickListItem(R.id.recyclerViewId, itemPosition) clickListItemChild( R.id.recyclerViewId, itemPosition, R.id.clickableViewId ) scrollListToPosition(R.id.recyclerViewId, itemPosition)
10. And more, and more useful functions… clickMenu(R.id.menuItemId) clickSpinnerItem(R.id.spinnerId, 2) openDrawer() refresh() closeKeyboard() swipeViewPagerForward() …
11. Assertions with Barista
12. Espresso onView(withId(R.id.button)).check(isDisplayed()) Barista assertDisplayed(R.id.button)
13. assertDisplayed(R.id.buttonId) assertDisplayed(R.string.textId) assertDisplayed(“Displayed!”) assertDisplayed(R.id.buttonId, “Displayed!”)
14. assertDisplayed assertNotDisplayed assertEnabled assertDisabled assertNotExist assertChecked assertUnchecked assertHasAnyDrawable assertHasDrawable assertHasAnyBackground assertDrawerIsOpen assertDrawerIsClosed assertContains assertNotContains

21. PermissionGranter.allowPermissionsIfNeeded( Manifest.permission.GET_ACCOUNTS )
22. Need more goodies?
23. PermissionGranter.allowPermissionsIfNeeded( Manifest.permission.GET_ACCOUNTS )
24. Need more goodies?
25. @get:Rule val clearPreferenceRule = ClearPreferenceRule() // Clear all app’s SharedPreferences @get:Rule val clearDatabaseRule = ClearDatabaseRule() // Delete all tables from all the app’s SQLite Databases @get:Rule val clearFilesRule = ClearFilesRule() // Delete all files in getFilesDir() and getCacheDir()
26. Need more goodies?
27. @Test @AllowFlaky(attempts = 5) fun myTest() { … } @Test @Repeat(times = 5) fun myTest() { … }
28. Can it be even simpler by default?
29. @get:Rule val baristaRule = BaristaRule.create(MyActivity::class.java) baristaRule.launchActivity() //…
30. The rule assumes some sane defaults: - Retry flaky tests: 10 attempts - Launch activity automatically: false - Initial touch mode enabled: true - Clear preferences - Clear databases - Clear files
