Unit testing custom parse class

Client SDKs Android SDK
#1

Hello,

I want to unit test my custom parse classes. I am very very veryyyy suprised that there is not ONE SINGLE WORD about unit testing Custom Parse classes in the documentation.

Here is my Custom user class

@ParseClassName("User")
data class User(var userName: String, var password: String, var eMail: String) : ParseObject() {

@Inject constructor(): this("","","")

fun checkNameExists() = getQuery().whereEqualTo("name", userName).findInBackground() != null

fun checkEmailExists() = getQuery().whereEqualTo("email", eMail).findInBackground() != null

And here my test

class UserUnitTest {
val testUserCorrect = ParseObject.create(User::class.java)
val testUserWrong: User = ParseObject.create(User::class.java)

@Before
fun beforeEach() {}

@Test
fun Check_if_email_already_exists() {
    testUserCorrect.eMail = "[email protected]"
    testUserWrong.eMail = "[email protected]"

    val correct = testUserCorrect.checkEmailExists()
    val wrong = testUserWrong.checkEmailExists()

    assert(true) { correct }
    assert(false) { wrong }

}

Error Stack
