我正在尝试使用androidX espresso库通过工具测试来测试我的UI。 在我的年级,我有:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: "kotlin-kapt"
android {
compileSdkVersion 28
defaultConfig {
applicationId "it.zehus.mybike"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
android.defaultConfig.manifestPlaceholders = ['appAuthRedirectScheme': 'net.openid.appauthdemo']
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
def lifecycle_version = "2.0.0"
// ViewModel and LiveData
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
// room persistence library
def room_version = "2.1.0-alpha04"
implementation "androidx.room:room-runtime:$room_version"
kapt "androidx.room:room-compiler:$room_version" // use kapt for Kotlin
// optional - Coroutines support for Room
implementation "androidx.room:room-coroutines:$room_version"
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
// Espresso
androidTestImplementation 'androidx.test:runner:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0'
implementation project(path: ':remotemanager')
implementation "org.jetbrains.kotlin:kotlin-reflect:1.3.21"
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
// required if you want to use Mockito for unit tests
testImplementation 'org.mockito:mockito-core:2.24.5'
// required if you want to use Mockito for Android tests
androidTestImplementation 'org.mockito:mockito-android:2.24.5'
// Bluetooth sdk
implementation project(path: ':bluetoothmanager')
// Custom views
implementation project(path: ':customviews')
}
按照documentation中的说明,我正在尝试在测试中导入ActivityTestRule类,但是未解析该引用。
import androidx.test.filters.LargeTest
import androidx.test.runner.AndroidJUnit4
import org.junit.Rule
import org.junit.Test
import org.junit.runner.RunWith
// unresolved reference here
import androidx.test.rule.ActivityTestRule
import it.zehus.mybike.ui.ride.RideActivity
/**
* Instrumented test, which will execute on an Android device.
*
* See [testing documentation](http://d.android.com/tools/testing).
*/
// deprecated here
@RunWith(AndroidJUnit4::class)
@LargeTest
class FragmentDashboardUiTest {
@get:Rule // unresolved reference here
val activityRule = ActivityTestRule(RideActivity::class.java)
@Test
fun myClassMethod_ReturnsTrue() { }
}
我是在做错什么还是AndroidX测试库中有问题?
答案 0 :(得分:1)
我从this文档页面中发现,ActivityTestRule类位于AndroidX中的 androidx.test.rule 下。为了导入包,我简单地添加了:
androidTestImplementation 'androidx.test:rules:1.1.0'
我的礼物。
总结一下,我的gradle现在包含:
// Espresso
// Core library
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
// AndroidJUnitRunner and JUnit Rules
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test:rules:1.1.1'
答案 1 :(得分:1)
该类位于以下软件包中: androidx.test.ext.junit.rules;
因此,最重要的依存关系显然是:
androidTestImplementation'androidx.test.ext:junit:1.1.2'
我想知道为什么其他答案如此之大, 但这对我根本不起作用。
希望这对像我这样的人有帮助。
