Functional testing is a type of black box testing that tests software based on its specifications. It is important to do functional testing to check functionality and quality. There are several frameworks that can be used for functional testing Android apps, including Robotium, Selendroid, Robolectric, Calabash, and Espresso. Each framework has its own advantages and disadvantages for setting up and running tests.

- 19. Robotium assertTrue(mSolo.waitForText("42")); new Solo(getInstrumentation(), getActivity()); Setup Checking result mSolo.assertCurrentActivity("Started", MainActivity.class); mSolo.clickOnText("7"); mSolo.clickOnText("×"); mSolo.clickOnText("6"); mSolo.clickOnText("="); The Test
- 21. Robotium APIs are easy to use Not the fastest Extensive documentation and examples
- 24. Selendroid Sort of WYSWYGS Java BasedJ
- 25. Selendroid @BeforeClass public static void startSelendroidServer() throws Exception { SelendroidConfiguration config = new SelendroidConfiguration(); config.addSupportedApp("apk/resigned-SampleApp.apk"); mSelendroidServer = new SelendroidLauncher(config); mSelendroidServer.launchSelendroid(); SelendroidCapabilities caps = new SelendroidCapabilities(“droidcon.nl.calculator:"); mSDriver = new SelendroidDriver(caps); } Setup

- 34. Robolectric EditText resultText = (EditText) mTestAct.findViewById(R.id.resText); assertEquals("42", resultText.getText().toString()); Checking result mTestAct.findViewById(R.id.num_7).performClick(); mTestAct.findViewById(R.id.op_mul).performClick(); mTestAct.findViewById(R.id.num_6).performClick(); mTestAct.findViewById(R.id.op_equ).performClick(); The Test
- 36. Robolectric Does not require emulator or device Extends JUnit framework Does not run on actual device Great performance
