Androidx Robolectric配置

Question

我试图在我的项目中使用Robolectric，但我遇到了一个障碍，不知道如何解决它。我认为这是一个配置问题，因为我甚至无法运行最基本的测试。

下面是我的依赖项；

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.3.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.navigation:navigation-fragment:2.2.2'
implementation 'androidx.navigation:navigation-ui:2.2.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
implementation 'androidx.navigation:navigation-fragment-ktx:2.2.2'
implementation 'androidx.navigation:navigation-ui-ktx:2.2.2'
implementation 'androidx.preference:preference:1.1.1'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'com.google.guava:guava:28.2-android'
androidTestImplementation 'androidx.test:core-ktx:1.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test:rules:1.2.0'
androidTestImplementation ('org.robolectric:robolectric:4.3.1') {
    exclude group: "org.apache.maven"
}

如果我没有包含exclude组指令，我会得到一堆库冲突。

这是我的第一个测试；

@RunWith(RobolectricTestRunner::class)
class RoboTest {

    @Test
    fun test() {
        Thread.sleep(9000)
    }
}

当我尝试运行它时，我得到了下面的堆栈跟踪；

我试着用谷歌搜索它，但我想我找不到我遇到的同样的情况，我也试过无效缓存/重启，但没有做任何事情。

有什么帮助吗？

我将文件从/androidtest移动到/test (单元测试)，并相应地更新了依赖关系；

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.3.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.navigation:navigation-fragment:2.2.2'
implementation 'androidx.navigation:navigation-ui:2.2.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
implementation 'androidx.navigation:navigation-fragment-ktx:2.2.2'
implementation 'androidx.navigation:navigation-ui-ktx:2.2.2'
implementation 'androidx.preference:preference:1.1.1'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'com.google.guava:guava:28.2-android'
/*androidTestImplementation 'androidx.test:core-ktx:1.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test:rules:1.2.0'*/
testImplementation 'junit:junit:4.12'
testImplementation ('org.robolectric:robolectric:4.3.1')

在docs中提到了这个解决方案。

哦，天哪，我脸上是不是有鸡蛋。
