For an app I am making I have added the following UI test code:
@LargeTest
@RunWith(AndroidJUnit4::class)
class MainActivityTest {
@Rule
@JvmField
var mActivityTestRule = ActivityTestRule(MainActivity::class.java)
@Test
fun uitest_dialogIsShown() {
onView(withId(R.id.floatingActionButton)).perform(click())
onView(withText("Please input an appropriate span count value between 1 and 100:"))
.inRoot(isDialog())
.check(matches(isDisplayed()))
}
}
Whenever I run UI tests, I get the following exception:

Unfortunately, I have tried to look at other people's questions who have had the same problem and the solutions offered have not been of help - it would be great if I could get this issue resolved so I can make UI tests for my app.
Here is my build.gradle file:
plugins {
id 'com.android.application'
id 'kotlin-android'
}
android {
compileSdk 31
testOptions {
unitTests.includeAndroidResources = true
}
defaultConfig {

minSdk 27
targetSdk 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures {
viewBinding true
}
testOptions {
unitTests.returnDefaultValues = true

}

I have no idea what's causing this issue.
If anyone can assist that would be great!
(If this question is poorly written please let me know.)
CodePudding user response：
Espresso are not unit tests and you're probably lacking a dependency:
testImplementation "androidx.test:monitor:1.4.0"
CodePudding user response：
I fixed this problem by removing the following line in my build.gradle file:
implementation 'androidx.test:core-ktx:1.4.0'
