我有一个 Android 项目,我正在尝试运行 Instrumentation 测试以使用 AndroidStudio,但是当我尝试为测试运行整个类文件时,我得到了如下所述的异常:
java.lang.TypeNotPresentException: Type android.support.test.runner.AndroidJUnit4 not present
Caused by: java.lang.ClassNotFoundException: android.support.test.runner.AndroidJUnit4
有趣的是,我可以在这个 Instrument Test 类中运行单个方法,而不是整个类。我的应用程序的 build.gradle 文件如下:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
lintOptions {
abortOnError false
}
compileSdkVersion 28
defaultConfig {
applicationId "com.sarpuner.journal"
minSdkVersion 19
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'
}
}
buildToolsVersion '27.0.3'
}
repositories {
maven { url "https://dl.bintray.com/ijabz/maven" }
}
dependencies {
androidTestImplementation 'com.android.support:support-annotations:27.1.1'
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'dev.dworks.libs:volleyplus:0.1.4'
implementation 'com.google.code.gson:gson:2.8.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:rules:1.0.2'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'org.jsoup:jsoup:1.11.3'

implementation 'net.jthink:jaudiotagger:2.2.3'
api 'com.google.guava:guava:26.0-android'
}
而 InstrumentTest 类如下:
package com.sarpuner.journal
import android.support.test.InstrumentationRegistry
import android.support.test.runner.AndroidJUnit4
import android.util.Log
import org.junit.Test
import org.junit.runner.RunWith
import org.junit.Assert.*
import java.io.File
private const val INSTRUMENT_TAG = "InstrumentTest"
// TODO: There is a problem here with the class run!
@RunWith(AndroidJUnit4::class)
class ExampleInstrumentedTest {
private val appContext = InstrumentationRegistry.getTargetContext()
@Test
fun useAppContext() {
// Context of the app under test.
assertEquals("com.sarpuner.journal", appContext.packageName)
}
@Test
fun downloadAndSaveAudio() {
val url = "http://telechargement.rfi.fr/rfi/francais/audio/jff/201808/journal_francais_facile_20h00_-_20h10_tu_20180809.mp3"
val name = "09-08-2018.mp3"
val f = File(appContext.filesDir, name)
Log.d(INSTRUMENT_TAG, f.absolutePath)
downloadAudio(url, f)
}
@Test
fun downloadAndSaveTranscript() {
val url = "https://savoirs.rfi.fr/fr/apprendre-enseigner/langue-francaise/journal-en-francais-facile-09082018-20h00-gmt"
val name = "09-08-2018.txt"
val f = File(appContext.filesDir, name)
downloadText(url, f)
}
@Test
fun addLyricsToAudio() {
}
}
非常感谢任何帮助/指导,谢谢。
最佳答案
这是由于 Android Studio 尝试将检测测试作为 JUnit 测试来执行的。
我必须转到“编辑配置...”并从 Android JUnit 组中删除配置,然后手动添加到“Android Instrumented Tests”组。在此之后,我执行测试没有问题。
在 Android Studio 中,点击 Run > Edit Configurations
。
