java - 无法在Android应用程序中运行测试

我正在尝试按照教程学习我的android应用程序的工具测试，但不幸的是，我一直收到java.lang.IllegalStateException: No instrumentation registered! Must run under a registering instrumentation.错误。我已经在gradle文件中添加了所需的依赖项，但仍然无法使其运行。这是我的测试文件：

package com.example.georgek.notekeeper;

import android.support.test.runner.AndroidJUnit4;

import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import androidx.test.espresso.ViewInteraction;
import androidx.test.rule.ActivityTestRule;
import androidx.test.runner.AndroidJUnitRunner;

import static androidx.test.espresso.Espresso.onView;
import static androidx.test.espresso.action.ViewActions.click;
import static androidx.test.espresso.action.ViewActions.closeSoftKeyboard;
import static androidx.test.espresso.action.ViewActions.typeText;
import static androidx.test.espresso.matcher.ViewMatchers.*;
import static org.junit.Assert.*;

@RunWith(AndroidJUnit4.class)
public class NoteCreationTest extends AndroidJUnitRunner {

    @Rule
    public ActivityTestRule<NoteListActivity> mNoteListActivityActivityTestRule =
            new ActivityTestRule<>(NoteListActivity.class);

    @Test
    public void createNewNote() {
//        ViewInteraction fabNewNote = onView(withId(R.id.fab));
//        fabNewNote.perform(click());
        onView(withId(R.id.fab)).perform(click());
        onView(withId(R.id.text_note_title)).perform(typeText("Test note title"));
        onView(withId(R.id.text_note_text)).perform(typeText("This is the body of our test note"),
                closeSoftKeyboard());
    }


}

和我的gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.georgek.notekeeper"
        minSdkVersion 24
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0'
    androidTestImplementation 'androidx.test:runner:1.1.0'
    androidTestImplementation 'androidx.test:rules:1.1.0'
    androidTestImplementation 'com.android.support:support-annotations:28.0.0'
    androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.1.0'

}

这是我收到的错误消息：

注意，我已经看到了问题this和this，但都没有帮助我解决问题。

implementation 'com.android.support.constraint:constraint-layout:1.1.3' implementation 'com.android.support:design:28.0.0' androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0' androidTestImplementation 'androidx.test:runner:1.1.0' androidTestImplementation 'androidx.test:rules:1.1.0' androidTestImplementation 'com.android.support:support-annotations:28.0.0' androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.1.0'}

或替换您的依赖项：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
