本文介绍了尝试模拟任何类都会生成 ExceptionInInitializerError的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

问题描述

当我运行以下代码时:

public class ActivityTest extends ActivityInstrumentationTestCase2<MainActivity> {
    ....
    public void testCanCreateMockito() {
        List mockedList = Mockito.mock(List.class);
    }
}

我得到以下异常:

这发生在任何类中,List 只是一个简单的例子.我的 gradle 依赖项是:

This occurs with any class, List was just an easy example. My gradle dependencies are:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.0'
    androidTestCompile "org.mockito:mockito-core:1.+"
    androidTestCompile files('libs/dexmaker-mockito-1.0.jar')
    androidTestCompile files('libs/dexmaker-1.0.jar')
}

我已将 gradle 升级到 1.1,尝试使用实验性单元测试功能,但没有,似乎没有任何区别.怎么回事?

I've upgraded gradle to 1.1, tried using the experimental unit test feature and not, nothing seems to make a difference. What's going on?

推荐答案

我在缺少两个 dexmaker 依赖项时收到此错误.

I received this error when I was missing the two dexmaker dependencies.

将这些行添加到 app/gradle.build 文件对我有用.

Adding these lines to the app/gradle.build file is working for me.

androidTestCompile 'org.mockito:mockito-core:1.10.19'
androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'

我也在使用 Android Studio,发现更改依赖项后重启 AS 是个好主意.

I am also using Android Studio and have found it to be a good idea to restart AS after altering the dependencies.
