I want to write a unit test. Therefore I need MutableLiveData. I started with a very basic test for setup but I cannot instantiate a MutableLiveData object. I is always null when I run the test. Do I have to mock anything? Any suggestions?
#RunWith(MockitoJUnitRunner.class)
public class DefaultLiveDataTest {
private static final int EXPECTED = 5;
private final MutableLiveData<Integer> underTest = new MutableLiveData<>();
#Test
public void exampleTest() {
underTest.setValue(EXPECTED); //underTest is Null
assertEquals(underTest.getValue().intValue(), EXPECTED);
}
}
java.lang.NullPointerException

Looks like you are missing the android.arch.core:core-testing dependency.
testImplementation "android.arch.core:core-testing:1.1.1"
This allows you to use the InstantTaskExecutorRule in your test, which will get rid of the isMainThread call.
https://developer.android.com/reference/android/arch/core/executor/testing/InstantTaskExecutorRule.html
#Rule
public InstantTaskExecutorRule instantTaskExecutorRule = new InstantTaskExecutorRule();
Add an executor InstantTaskExecutorRule() as a member of the Test class
A JUnit Test Rule that swaps the background executor used by the
Architecture Components with a different one which executes each task
synchronously. You can use this rule for your host side tests that use
Architecture Components.
//#RunWith(JUnit4::class) // For JUnit4
#ExtendWith(InstantExecutorExtension::class) // For JUnit5
class FilterViewModelTest {
#Rule #JvmField
val instantTaskExecutorRule = InstantTaskExecutorRule()
#Test

InstantTaskExecutorRule
I had this error and solved it by adding InstantTaskExecutorRule:
private lateinit var contactProfileViewModel: ContactProfileViewModel
private val getStatusesForContact: GetStatusesForContact = mockk(relaxed = true)
private val getStory: GetUserLastStory = mockk(relaxed = true)
private val successStatusesCaptor = slot<((List<StatusDomain>) -> Unit)>()
private val successStoryCaptor = slot<((List<StoryDomain>) -> Unit)>()
#get:Rule
val rule: TestRule = InstantTaskExecutorRule()
#Before
fun setUp(){
contactProfileViewModel = ContactProfileViewModel(getStatusesForContact, getStory)
}

I was writing unit tests for my room db operations, everything was working great but, I decided to write and inject the DataBaseBuilder within TestAppModule using Hilt, but seems like I am getting the following error when i run the tests. I also created a custom HiltRunnerClass and used it in gradle as testInstrumentationRunner "com.rimapps.wisetest.HiltTestRunner"

I am new to android testing and I don´t know how to solve this problem.
Trying to run the following test file from my project:
#RunWith(AndroidJUnit4::class)
class AppDatabaseTest {
private lateinit var userDAO: UserDAO // custom DAO interface
private lateinit var db: AppDatabase
#Before
fun createDb() {
db = Room.inMemoryDatabaseBuilder(
ApplicationProvider.getApplicationContext(),
AppDatabase::class.java
).allowMainThreadQueries().build()
userDAO = db.userDAO()
}
#After
#Throws(IOException::class)
fun closeDb() {
db.close()
}
#Test
#Throws(Exception::class)
fun insertAndReadUser() {
val user = User(
1,
"123",
"Test Name",
"link.to/name/image#from_the.web"
)
userDAO.insert(user)
val inserted = userDAO.getByUID(1)
assertThat(inserted).isNotNull()
}
}
Throws the following error on the run log:
java.lang.RuntimeException: Delegate runner androidx.test.internal.runner.junit4.AndroidJUnit4ClassRunner for AndroidJUnit4 could not be found.

What could be causing this error and how to fix it?
Android Studio 4.1.1
I managed to find the issue.
In fact, I had put the testing file on the wrong folder, the [test] folder instead of [androidTest] folder. Moving the file to the correct folder managed to solve the issue.
I am trying to write my first test and I have problem figuring out the right dependencies to get everything to work. Here is my test class
class EmployeeDatabaseTest {
private lateinit var employeeDao: EmployeeDAO
#Before
fun setup() {
EmployeeDatabase.TEST_MODE = true
employeeDao = EmployeeDatabase.getDatabase(??).employeeDao()
}
#Test
fun should_Insert_Employee_Item() {
val employee = Employee("xx", "xx", 31, Gender.MALE)
employee.id = 1
runBlocking { employeeDao.addNewEmployee(employee) }
val employeeTest = runBlocking { getValue(employeeDao.getEmployeeById(employee.id!!)) }
Assert.assertEquals(employee.name, employeeTest.name)
}
}
Normally I would obtain context by InstrumentationRegistry.getContext()...but InstrumentationRegistry can't be resolved. It also can't resolve getValue(..) method. I am new to testing but I bet is something with dependencies. Here is my build.gradle:
dependencies {
...
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test:rules:1.2.0'
androidTestImplementation 'org.hamcrest:hamcrest-library:1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
androidTestImplementation 'androidx.test.uiautomator:uiautomator:2.2.0'
androidTestImplementation 'androidx.test:core:1.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
}
defaultConfig {
...
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
Do I miss something I am I doing something wrong?
A simple Context can be resolved with
androidx.test.core.app.ApplicationProvider.getApplicationContext()
which is part of the core module
androidTestImplementation 'androidx.test:core:1.2.0'
When you use Robolectric, you can also have it as
testImplementation 'androidx.test:core:1.2.0'
I am trying to use Room in my project. Gradle syncing files well, but I get RunitomeException when trying to get database instance.
"Caused by: java.lang.RuntimeException: cannot find implementation for com.fillooow.android.testtochka.BusinessLogic.database.GithubUserSearchDataBase. GithubUserSearchDataBase_Impl does not exist"
I searched this issue and find that solution is to add this lines into build.gradle file:
implementation "android.arch.persistence.room:runtime:1.1.1"
implementation "android.arch.persistence.room:rxjava2:1.1.1"
kapt "android.arch.persistence.room:compiler:1.1.1"

return INSTANCE

}
}
}
Project were cleared and rebuild a lot of times.
So, maybe I missed something?
Your gradle file looks fine. Just be sure to Sync it after you have added the proper imports.
What you are missing is the #Database annotation on top of your Database class.
#Database(entities = [Entity1::class, Entity2::class, Entity3::class, Entity4::class], version = 1)
abstract class GithubUserSearchDataBase : RoomDatabase(){
abstract fun githubUserSearchDataDao(): GithubUserSearchDataDao
companion object {
private var INSTANCE: GithubUserSearchDataBase? = null
fun getInstance(context: Context): GithubUserSearchDataBase?{
if (INSTANCE == null){
synchronized(GithubUserSearchDataBase::class){
INSTANCE = Room.databaseBuilder(context.applicationContext,
GithubUserSearchDataBase::class.java,
"github.db")
.build()
}
}
return INSTANCE
}
fun destroyInstance(){
INSTANCE = null
}
}
}
In the entities attribute of the #Database annotation you must put an array with all the classes of your model annotated with the #Entity annotation. I put there fake names, you should put the proper ones.

}
I still don't know why. Any ideas?
Thank you?
