QUESTION

android datastore-preferences: Property delegate must have a 'getValue(Context, KProperty<*>)' method

Asked 2022-Feb-28 at 12:19

I'm writing a jetpack compose android app, I need to store some settings permanently.

I decided to use androidx.datastore:datastore-preferences:1.0.0 library, I have added this to my classpath.

According to the https://developer.android.com/topic/libraries/architecture/datastore descripton I have added this line of code to my kotline file at the top level:

val Context.prefsDataStore: DataStore by preferencesDataStore(name = "settings")

But I get a compile error:

e: ...SettingsViewModel.kt: (13, 50): Property delegate must have a 'getValue(Context, KProperty<*>)' method. None of the following functions is suitable: 
public abstract operator fun getValue(thisRef: Context, property: KProperty<*>): DataStore<Preferences> defined in kotlin.properties.ReadOnlyProperty

How can I use the datastore-preferences?

My build.gradle file:

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-kapt'

}

I got this error because of an incorrect import:

import java.util.prefs.Preferences

So fix it by

import androidx.datastore.preferences.core.Preferences

or

val Context.dataStore by preferencesDataStore(name = "settings")

QUESTION

java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Comparator java.util.TreeMap.comparator accessible:module

Asked 2022-Jan-19 at 19:22

This is my first cucumber project and i followed a tutorial when setting everything up. It all seems to be the same but for some reason i get this:

java.lang.ExceptionInInitializerError. Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Comparator java.util.TreeMap.comparator accessible: module java.base does not "opens java.util" to unnamed module @74ad1f1f

Any idea how to solve this error ?

Below i have posted everything that comes out in my console as well as my pom file in case there is an issue with my dependencies eventhough the guy from the tutorial's pom file is identical.

This is everything that comes out in my Console.

I solved my problem. Turns out the JRE that eclipse had automatically downloaded and was using wasn't compatible with this version of cucumber. I manually changed the path to a jre 1.8 that i had in my ProgramFilex(x86)/Java folder and now everything works fine.

You are missing

QUESTION

Fail to restTemplate create with @PowerMockIgnore in powermock

Asked 2021-Dec-12 at 02:49

I need a powermock for private method test.
It is working well if I use only @RunWith(PowerMockRunner.class) without @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class).

I need to use @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class) for @autowired. But It doesn't fail to start.

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
@SpringBootTest
public class SpringPowerMockTest {

}

Threfore I add this through https://github.com/powermock/powermock/issues/864

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
// I added this
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*", 
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", 
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {

    @Test
    public void test() {
      //success
    }

}

It was working well.

Therefore, I started to write code for test

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*", 
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", 
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {

    @Test
    public void initalize() throws IOException {
        RestTemplate restTemplate = new RestTemplate();
        .....
    }


}

But I couldn't start with this error message

I have no idea why this is happening, I've tried for a couple of weeks to solve it but with no luck - I am still getting the same exception whenever I try and execute my UI tests. This is extremely bad as I am actually committing faulty code on a regular basis! I really need this issue fixed.

Answered 2021-Dec-10 at 17:51

I had this same issue, too. I spent a ton of time researching it, and ultimately found that your issue stems from this: https://issuetracker.google.com/issues/204506297

Essentially, that version of the Espresso library tries to use an enum from another library that it does not have scoping access to. They have fixed the issue here: https://github.com/android/android-test/pull/1174

Unfortunately, at the time of writing 3.5.0-alpha03 is the latest version. So, you can either wait for alpha04/beta01 or downgrade back to 3.4.0 until the issue is fixed.

You didn't show your Product entity.

But I assume that the ID is generated with @GeneratedValue that's why Hibernate thinks is an existing entity.

You must not set the ID if the ID is generated by Hibernate.

QUESTION

Configuring Axon in Spring for integration testing

Asked 2021-Sep-20 at 15:47

Still new to java and axon, having troubles to setup integration test suite using spring and axon.

Basically, I have some process, which:

starts with command1
goes to command handler on aggregate and event1 is dispatched
event1 is processed by some policy (event listener) and command2 is generated
command2 is processed by command handler service (thus has no aggregate id) because I need to process something with third party
event2 is dispatched and processed by another event listener, so command3 is dispatched
command3 is processed by aggregate and event3 is dispatched

I use axon tests for unit testing aggregates and it works great.

But I would like to add "integration" tests to:

check the whole flow, like: when command1 dispatched then event1, event2, event3 is recorded (actually don't care about fields, just to have confidence the whole thing is glued as expected)
check the service command handler work as expected in manner "when command2 dispatched, then event2 is recorded"

I was partly succesful with 1) by doing:

package com.example.integration;

import org.axonframework.commandhandling.gateway.CommandGateway;
import org.axonframework.eventsourcing.eventstore.EmbeddedEventStore;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.Import;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.Arrays;
import java.util.UUID;

@RunWith(SpringRunner.class)
@SpringBootTest
@Import(IntegrationTestConfig.class)
public class ExampleIntegrationTest
{

    @Autowired
    private CommandGateway commandGateway;

    @Autowired
    private EmbeddedEventStore eventStore;

    @Test
    public void itShouldStoreCorrectEvents() {
        var aggregateId = UUID.randomUUID().toString();
        var exampleCommand = new ExampleCommand(aggregateId);

        whenCommandIsDispatched(exampleCommand);

        thenExpectedEventsRecorded(
                Arrays.asList(
                        Event1.class,
                        Event3.class
                ),
                aggregateId
        );
    }

    private void whenCommandIsDispatched(Command command)
    {
        commandGateway.sendAndWait(command);
    }

    private void thenExpectedEventsDispatched(java.util.List<Class<?>> expectedEventTypes, String id)
    {
        var events = eventStore.readEvents(id);
        while (events.hasNext()) {
            Assert.assertEquals(
                    expectedEventTypes.get(Math.toIntExact(events.getLastSequenceNumber())),
                    events.next().getPayloadType()
            );
        }
    }
}

And having IntegrationConfigTest:

package com.example.library.test;

import org.axonframework.eventhandling.EventBus;
import org.axonframework.eventsourcing.eventstore.EmbeddedEventStore;
import org.axonframework.eventsourcing.eventstore.EventStorageEngine;
import org.axonframework.eventsourcing.eventstore.inmemory.InMemoryEventStorageEngine;
import org.springframework.boot.test.context.TestConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Primary;

@TestConfiguration
public class IntegrationTestConfig {

    @Bean
    @Primary
    public static EventBus createSpyEventBus() {
        return new EmbeddedEventStore.Builder().storageEngine(new InMemoryEventStorageEngine()).build();
    }
}

Which is nice and test passes, but I didn't find a way how to test events dispatched from the service command handler (Event2 in my example) - id of aggregate is needed here: eventStore.readEvents(id). EDIT: But I dont want to put aggregate id in, since event was not recorded on any aggregate - it was dispatched right into event gateway in service/singleton command handler.

Any ideas how can I get all dispatched events so I can also assert Event2 was dispatched?

Or am I missing something here? :)

ANSWER

Answered 2021-Sep-01 at 11:56

The initializing command handler that receives command1 to create the aggregate might return the aggregateId, so you can fetch the returned result and use the id for future reference.

 ...
 public class MyAggregate {
     @CommandHandler
     public static MyAggregate create(CreateCmd cmd) {
          MyAggregate a = new MyAggregate();
          AggregateLifecycle.apply(new CreatedEvent(UUID.randomUuid().toString());
          return a;
     }
 }
 ....

 String generatedId = commandGateway.sendAndWait(new CreateCmd(null));
 .... // continue

when i added the plugins kotlin-android and kotlin-kapt it said that they weren't found. therefore i had to change the app gradle to be like this (based on other posts)

// Top-level build file where you can add configuration options common to all sub-projects/modules.
task clean(type: Delete) {
    delete rootProject.buildDir
}
buildscript {

    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.30"
    }
}

allprojects {
    configurations.all {
        resolutionStrategy {
            cacheChangingModulesFor 0, 'seconds'
        }
    }
}

but that gave me these errors

com/android/build/gradle/BaseExtension
> com.android.build.gradle.BaseExtension


Unable to load class 'com.android.build.gradle.BaseExtension'.

in the database file I did as follows:

private const val DATABASE_NAME = "FakeCaller"


@Database(entities = [Contact::class, RingTone::class], version = 1, exportSchema = false)
abstract class DataBase:RoomDatabase() {

    abstract fun UserDao(): UserDao

    abstract fun RingDao():RingDao

//Implementing the DataBase
    companion object {
        @Volatile
        private var INSTANCE: DataBase? = null

        fun getInstance(context: Context): DataBase {
            synchronized(this) {
                var instance = INSTANCE

                if (instance == null) {
                    instance = Room.databaseBuilder(
                        context.applicationContext,
                        DataBase::class.java,
                        DATABASE_NAME
                    ).build()

                    INSTANCE = instance
                }
                return instance
            }
        }
    }
}

and connected everything to the RoomViewModel (I created a factory for it also)

class RoomViewModel(application: Application) : AndroidViewModel(application) {

    val readContactList : LiveData<List<Contact>>
    val readFileUri: LiveData<Uri>
    private val repository : Repository

    init {
        val dbInstance = DataBase.getInstance(application)
        val userDao = dbInstance.UserDao()
        val ringDao = dbInstance.RingDao()
        repository = Repository(userDao, ringDao)
        readContactList = repository.getContacts
        readFileUri = repository.getUri()
    }

    suspend fun getContact(id:Long): LiveData<Contact>{
        return repository.getContact(id)
    }
...
}

in MainActivity I made this

setContent {
            FakeCallerTheme {
                // A surface container using the 'background' color from the theme
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colors.background
                ) {
                    val context = LocalContext.current
                    val roomViewModel: RoomViewModel = viewModel(
                        factory = RoomViewModelFactory(context.applicationContext as Application)
                    )
                    Greeting("Android")
                }

i think there is an issue with the context but i don't know really. still learning...

please help

This should help.

Modern day approach:

inside the plugins block,

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-kapt' //Add this
}

Then, withing dependencies,

    kapt "androidx.room:room-compiler:$rootProject.roomVersion"

Well based on the comment below,

These are all that I have needed to build fine.


    implementation "androidx.room:room-ktx:$rootProject.roomVersion"
    kapt "androidx.room:room-compiler:$rootProject.roomVersion"
    androidTestImplementation "androidx.room:room-testing:$rootProject.roomVersion"

Hey wait, are you connected to the internet? These may need to be downloaded from the web by the studio (downloads automatically). If download does not start, please check whether gradle is configured for offline work. If it is, toggle the state and it will download.

Per the comment below, this seems to have solved the issue

project-level-build{
 dependencies{
  classpath 'com.android.tools.build:gradle:7.1.0-alpha04' 
  classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
 }
}

QUESTION

Mock a method coming from parent class to return a mocked data

Asked 2021-Sep-01 at 22:15

I have a method coming from another class which is the super class for the method I am testing. I wish to mock it such that when I reach that method, I just want to return a mocked data.

But currently, it keeps going into the method instead of skipping it and just assigning the mock data.

Could I please get some help on why my mocking is not working?

Please note that the parent class is actually coming from another dependency which we do not maintain and it's accessibility is protected.

Thus can't refactor the method being mocked and not looking to refactor the code. Just want to mock it.

Looking to achieve this either via mockito or powermock or combined if it comes to that. Thanks. ## Heading ##

This is the class and method being tested.

@Service
public class OfferService extends ParentClass { 

  // many other methods 

  public Object get() {
    // getHttpEntity() comes from ParentClass
    HttpEntity<Object> httpEntity = getHttpEntity("www.example.com"); // looking to mock this getHttpEntity method. I do not want to enter it. 

    // will not reach here. Failed at above line cos didn't mock getHttpEntity. 
    ResponseEntity<OfferResponses> responseEntity = restTemplate.exchange(endPoint, HttpMethod.GET, httpEntity, OfferResponses.class);
    return responseEntity.getBody();
  }

}

My Test which currently fails cos it keeps entering the getHttpEntity method.

package com.pack;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Matchers;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.modules.junit4.PowerMockRunner;

import static org.mockito.Matchers.eq;

import static org.powermock.api.mockito.PowerMockito.doReturn;
import static org.powermock.api.mockito.PowerMockito.spy;
import static org.powermock.api.mockito.PowerMockito.whenNew;

@RunWith(PowerMockRunner.class)
public class OfferServiceTest {

  @InjectMocks
  OfferService offerService;

  @Mock
  RestTemplate restTemplate;

  @Mock
  HttpEntity<Object> entity;

  @Before
  public void setup()  {
    offerService = new OfferService();
    MockitoAnnotations.initMocks(this);
  }

  // failing test 
  @Test
  public void getTest() throws Exception {
    OfferResponses offerResponses = new OfferResponses();
    ResponseEntity<OfferResponses> responseEntity = new ResponseEntity<>(offerResponses, HttpStatus.OK);

    PowerMockito.when(
            restTemplate.exchange(anyString(), Matchers.eq(HttpMethod.GET)
                    , Matchers.anyObject(),
                    Matchers.<Class<OfferResponses>>anyObject()))
            .thenReturn(responseEntity);

    OfferService spy = spy(offerService);
    doReturn(entity).when(spy, "getHttpEntity", Matchers.anyString());

    Object result = offerService.get();

    // assertions
  }
}

Answered 2021-Sep-01 at 22:15

So, since you want to spy your OfferService, you must invoke your get method on this spy.

With PowerMockito:

@RunWith(PowerMockRunner.class)
public class OfferServiceTest {

    @Spy
    @InjectMocks
    private OfferService offerService = new OfferService();

    @Mock
    private RestTemplate restTemplate;

    @Mock
    private HttpEntity<Object> entity;


    @Test
    public void test() {
        PowerMockito.when(offerService, "getHttpEntity", "www.example.com")
            .thenReturn(entity);

        PowerMockito.when(restTemplate.exchange(anyString(), any(), any(), any()))
                .thenReturn(something);

        assertEquals(someObject, offerService.get());
    }
}

Or it can be done without PowerMockito using ReflectionTestUtils:

@ExtendWith(MockitoExtension.class)
public class OfferServiceTest {

    @Spy
    @InjectMocks
    private OfferService offerService;

    @Mock
    private RestTemplate restTemplate;

    @Mock
    private HttpEntity<Object> entity;


    @Test
    public void test() {
        when(ReflectionTestUtils.invokeMethod(offerService, "getHttpEntity", "www.example.com"))
                .thenReturn(entity);

        when(restTemplate.exchange(anyString(), any(), any(), any()))
                .thenReturn(something);

        assertEquals(someObject, offerService.get());
    }
}
