What settings should I set? How to avoid deprecated class?

I would like to use espresso, after that try to use UiAutomator, how to set needed necessary settings?

I lost almost whole day.

@RunWith(AndroidJUnit4::class)
@LargeTest

class MainActivityTest {

    @Rule
    @JvmField
    var activityTest = ActivityTestRule(MainActivity::class.java)

    fun c(){
        assertEquals(1,1)
    }
}

GRADLE

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId "com.example.network"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.3.0'

You've not set the test runner correctly.

This line:

"android.support.test.runner.AndroidJUnitRunner"

should be instead:

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

as you are using the new androidx libraries instead of the old support ones.

Without this you'll get this No tests were found errors. Don't forget to add the testInstrumentationRunner keyword.

And add junit to androidTestImplementation also in de gradle file:

androidTestImplementation 'androidx.test.ext:junit:1.1.1'
