測試的Mockito框架的Android

不工作我開始寫單元測試我的應用程序，並有問題，Android Studio中Mockito功能。比如我不能嘲笑Context的對象。這是我非常基本的代碼：測試的Mockito框架的Android

ExampleUnitTest.java類：

package com.mypackage; 

import android.content.Context; 

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.mockito.Mock; 
import org.mockito.runners.MockitoJUnitRunner; 

import static org.mockito.ArgumentMatchers.any; 
import static org.mockito.Mockito.when; 

@RunWith(MockitoJUnitRunner.class) 
public class ExampleUnitTest { 

    @Mock Context context; 

    @Test 
    public void test() throws Exception { 
     when(context.getString(any(Integer.class))).thenReturn("Test"); 
    } 
}

在我的應用程序級的build.gradle文件我也有這樣的依賴關係：

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    compile 'com.android.support:appcompat-v7:25.0.1' 
    compile 'com.android.support:design:25.0.1' 
    compile 'com.google.android.gms:play-services:10.0.1' 
    testCompile 'junit:junit:4.12' 
    testCompile 'org.mockito:mockito-core:2.1.0' 
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" 
}

所以根據所有的教程，等等一切都應該沒問題。但是，當我嘗試運行我的測試，我得到這樣的例外：

org.mockito.exceptions.misusing.UnnecessaryStubbingException: 
Unnecessary stubbings detected in test class: ExampleUnitTest 
Clean & maintainable test code requires zero unnecessary code. 
Following stubbings are unnecessary (click to navigate to relevant line of code):

Please remove unnecessary stubbings. More info: javadoc for UnnecessaryStubbingException class.

    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144)

我在做什麼錯在這裏，我不能嘲笑簡單Context對象getString()方法的功能？

異常追蹤的前六行似乎很清楚。 –

我相信這是因爲你沒有實際使用的模擬。在測試類檢測

不必要stubbings：ExampleUnitTest

清潔&維護的測試代碼需要零不必要的代碼。
