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
}

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.
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:

I can't initialize MockWebServer on androidTest folder. I've already added this line on my gradle
androidTestCompile('com.squareup.okhttp3:mockwebserver:3.6.0') {
exclude group: 'com.squareup.okio', module: 'okio'
exclude group: 'com.squareup.okhttp3', module: 'okhttp'
}.
I tried to follow the implementation from https://github.com/riggaroo/android-retrofit-test-examples. I've cloned the project, change the version of MockWebServer used by this example to the latest one and it still works fine but the implementation from my project still gives me same error.

I do UITest with Espresso, and test login function in LoginActivity.java .
when running LoginScreenTest.java ,some exception got,the follow is exception message. I don't konw why LoginPresenter can be found but LoadIdlingResource cannot be found ,why and how to do.thanks very much!!!
the following is exception message.
