I have a RecyclerView Adapter with multiple ViewHolders. Each ViewHolder uses a ViewBinding Class to inflate the view. I am trying to write some test for the adapter class. Here is my test class.
#RunWith(AndroidJUnit4ClassRunner::class)
class HomeTest {
private lateinit var adapter: Adapterr
#Before
fun setup() {
adapter = Adapterr()
}
#Test
fun createViewHolder() {
adapter.updateAdapter(getDummyAdapterItems())
//Error happens on this line.
val p = RecyclerView(InstrumentationRegistry.getInstrumentation().context)
p.adapter = adapter
val viewHolder = adapter.onCreateViewHolder(p, 0)
assertThat(viewHolder, notNullValue())
}
I get the following error.

I even tried running it with a MockViewGroup Object, but I get the same error.
I have an Android Activity that implements an delegate interface which is called IMeetingRoomDelegate
interface IMeetingRoomDelegate {
fun onMeetingRoomFragmentClicked(homeFragment: MeetingRoomHomeFragment, meetingRoom: ParcelableMeetingRoomData)
}
I want to always assure that my Activity is always an implementation of IMeetingRoomDelegate.
How would I check this in Kotlin? I so far have this:
#RunWith(AndroidJUnit4::class)
class GivenTheMainActivityIsLoaded {
#get:Rule
val activityRule = ActivityTestRule<MainActivity>(MainActivity::class.java)
private lateinit var mainActivity: MainActivity
#Before
fun setup() {
this.mainActivity = activityRule.activity
}
#Test
fun thenThereShouldAlsoBeAnInstanceOfIMeetingRoomDelegatePresent() {
assertTrue(implementsInterface(this.mainActivity::class.java))
}
private fun implementsInterface(interf: Class<*>): Boolean {
return interf is IMeetingRoomDelegate
}
}
I've tried seeing what the issue is myself but the test runner is barely giving anything substantial away.

You could use the reified generics instead of asserting the reflections:
#Test
fun thenThereShouldAlsoBeAnInstanceOfIMeetingRoomDelegatePresent() {
assertTrue(this.mainActivity.implementsInterface())
}
private inline fun <reified T> T.implementsInterface(): Boolean {
return this is IMeetingRoomDelegate
}
In my test I need to start activity as singleton. So I use flag FLAG_ACTIVITY_SINGLE_TOP
Here my Espresso's test:
#RunWith(AndroidJUnit4::class)
class TradersActivityTest {
private var intent = Intent()
#Rule
#JvmField
var tradersIntentTestRule = IntentsTestRule(TradersActivity::class.java, false, false)
#Before
fun setup() {
mockServer = MockWebServer()
mockServer.start(8081)
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP)
}
#Test
fun network_clientError_showToast() {
mockServer.enqueue(MockResponse()
.setResponseCode(400))
tradersIntentTestRule.launchActivity(intent) // error here
onView(withText(R.string.client_error)).inRoot(ToastMatcher()).check(matches(isDisplayed()))
}
But when I start test network_clientError_showToast I get error:

You're starting your activity outside of an activity context, so you have to use FLAG_ACTIVITY_NEW_TASK along with your other flags:

fun setup() {
mockServer = MockWebServer()
mockServer.start(8081)
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_NEW_TASK)
}
I've tried today the new android testing support lib. I need the write external storage permission for my tests so I've created the following test with the new GrantPermissionRule.
ExternalDirTest.java
#Rule
public GrantPermissionRule mRuntimePermissionRule = GrantPermissionRule.grant(Manifest.permission.WRITE_EXTERNAL_STORAGE);
#Test
public void test() throws IOException {
Application.getApplication().createDir();
}
Application.java
public void createDir() throws IOException {
new File(Environment.getExternalStorageDirectory() + "/test").createNewFile();
}
Officially I get the permission (visible in the app settings). Nevertheless I get the following exception:

If I test the code manual it works perfectly.
Has someone facing the same problem or is it maybe a bug in the library itself?
Should now be fixed in version 1.0.2-alpha2
