I'm following the code here: Android Unit Test with Retrofit2 and Mockito or Robolectric
and I'm trying to run this code:
mockWebServer.enqueue(new MockResponse().setBody("your json body"));
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(mockWebServer.url("").toString())
//TODO Add your Retrofit parameters here
.build();
but at the build() method it throws :
java.lang.reflect.InvocationTargetException
java.lang.AssertionError

Ah figured it out. It was Robolectric:
changed:
#Config(constants = BuildConfig.class, sdk = JELLYBEAN, packageName = "com.test.mc.instagram")
TO
#Config(constants = BuildConfig.class, sdk = 23, packageName = "com.test.mc.instagram")

I use Airbnb's Epoxy 2.0 and I want to unit test my Controller. Whenever I try to instantiate a new Controller using Mockito it gives me a NPE.
Perhaps going down Mockito is the wrong route here. I've never used anything besides Mockito, Espresso and JUnit - perhaps I should look into Robolectric/Android AssertJ?
private MainController controller;
#Mock Context context;
#Mock MainContract.View view;
#Mock SharedPrefsManager sharedPrefsManager;
#Mock ImageViewAnimator imageViewAnimator;
#Mock DateFormatter dateFormatter;
#Before
public void setup()
{
MockitoAnnotations.initMocks(this);
controller = new MainController(context, view, sharedPrefsManager, imageViewAnimator, dateFormatter); //throws on this line
}

Using Roboletric with Mockito works and doesn't throw the NPE.
What I got, is a couple of methods to generate AES key. I'm doing test cases over it, but when I try to pass a test to verify it returns the String of the AES key, it fails.
The method to call is:
public String getAESString() {
return Base64.encodeToString(this.aesKey.getEncoded(), Base64.DEFAULT);
}
and the test: (the setupAES just call the generate AES method that it's already tested)
#Test
public void getAESString() throws NoSuchAlgorithmException {
setupAes();
assertNotNull(cryptoMancer.getAESString());
}
But I know, that the method getAesString, is working fine, because I'm using it a test Activity, and I can used it, without problems.
How can I avoid this error? (I mean, how I pass the test)
The error log i'm getting is:

Image, that shows the method working perfect in the app:
I'm making a cinema project, and i'm doing my unit tests.
When testing a method called addMovie:
i expect the exception thrown, but the test still fails.
public static void addMovie(Movie movie) {
MySQL.queryUpdate("INSERT INTO movies (title, genre, duration) VALUES " +
"('" + movie.getTitle() + "', '" + movie.getGenre() + "', '" + movie.getDuration() + "')");
}
Test method:
#Test(expected=MySQLIntegrityConstraintViolationException.class)
public void addMovieWithSameTitle() {
Movie.addMovie(m2);
And here is my error message:

What am i doing wrong? i imported the class and all
MySQLIntegrityConstraintViolationException is a checked exception, but your MySQL.queryUpdate hides the checked exceptions (no catch and no throws in addMovie). Therefore you are unable to catch it in the test.
I use ActiveAndroid library for working with the database. The automatic test crashes with an error when I create an object model.

I found a solution - https://github.com/kaeawc/testable-active-android/blob/master/app/src/test/java/io/kaeawc/activeandroidapp/model/ActiveAndroidModelSpec.java
But the fact is that in addition I need PowerMockRunner and RobolectricGradleTestRunner. The project uses the class Application (it is stored on the Component Dagger). Options from here did not help.
In the first case:
#RunWith(RobolectricGradleTestRunner.class)
#Config(constants = BuildConfig.class, manifest = "src/test/TestManifest.xml", sdk = Build.VERSION_CODES.LOLLIPOP)
#PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
#PrepareForTest({ Cache.class, TableInfo.class, Context.class, ContentResolver.class, ContentProvider.class, ContentValues.class })
#SuppressStaticInitializationFor("com.activeandroid.content.ContentProvider")
public class BaseTest {
#Rule
public PowerMockRule rule = new PowerMockRule();
#Test
public void setup() throws Exception {
PowerMockito.mockStatic(ContentProvider.class);
PowerMockito.when(ContentProvider.createUri(Model.class, 0l)).thenReturn(null);
assertTrue(ContentProvider.createUri(null, null) == null);
}
}
Stacktrace:

What should I do?
For the exception "org.powermock.api.mockito.ClassNotPreparedException: "
You could try to put this annotation on top of the class declaration or test method.
#RunWith(PowerMockRunner.class)
#PrepareForTest(CommPortIdentifier.class)
All the best,
So here is the class and method I want to create a test for:
public class RequestController {
private GetAllInter getAnalytics;//This is an interface
#RequestMapping(value ="",method=RequestMethod.GET)
public String getAllAnalytics(){
log.debug("Processing request for all analytics");
String result;
try {
result = getAnalytics.getAll();
} catch (Exception e) {
result = "Could not retrieve full list of analytics";
log.error(result,e);
}
return result;
}
Specifically I want mock the getAnalytics.getAll() so it returns a String I already defined. Instead of the method doing its thing. This is my code:
public class RequestControllerTest extends Mockito{
private String allAnalyticsStr = "Hello";
#Test
public void testGetAllAnalytics(){
GetAllInter getAll = mock(GetAllInter.class);
when(getAll.getAll()).thenReturn("what");
RequestController requestController = new RequestController();
assert(requestController.getAllAnalytics().equals("Hello"));
}
And when I try to run the test this is the error im getting:
16:17:03.240 [main] DEBUG dar.RequestController - Processing requst for all analytics
16:17:03.248 [main] ERROR dar.RequestController - Could not retrieve full list of analytics

Any idea what I'm doing wrong? Is there another way to do this? Is it because I am mocking an interface of the class and not the class itself?
You need to replace RequestController#getAnalytics field with mocked GetAllInter instance before executing test.
GetAllInter getAll = mock(GetAllInter.class);
when(getAll.getAll()).thenReturn("what");
That statement doesn't effect RequestController's getAnalytics instance behavior until you set it as RequestController's field.
I found similar question
mockito - mocking an interface - throwing NullPointerException
The easiest way is provide setter for RequestController#getAllanalytics or provide RequestController constructor taking GetAllInter argument.
But using #InjectMocks would be nicer solution since you don't need to modify the RequestController class for testing.
