我开始为我的应用程序编写测试,目前在Mockito框架中遇到了非常奇怪的行为。基本上我有以下简单的测试类:
package com.app.greatapp;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.runners.MockitoJUnitRunner;
import static junit.framework.Assert.assertTrue;
import static org.mockito.Mockito.when;
@RunWith(MockitoJUnitRunner.class)
public class DateToolsTests {
@Mock Context context;
@Before
public void setUp() {
when(context.getString(R.string.app_name)).thenReturn(" app");
}
@Test
public void makeMyTest() {
assertTrue(context.getString(R.string.app_name).equals(" app"));
}
}
我在两个项目(以及在同一台PC中)使用上面的类(完全相同的代码) 用于测试目的。在一个项目中测试通过正常但在另一个项目中我得到了这样的例外:

似乎mockito因某些奇怪的原因无法模仿Context
对象......
在两个项目build.gradle文件中,我有以下依赖项:
testCompile 'org.mockito:mockito-core:1.10.19'
使用最新的gradle插件版本:
classpath 'com.android.tools.build:gradle:2.2.3'
有人有想法吗?根据文档,教程等看起来它看起来非常基本,并且很奇怪为什么它在一个项目中工作而在其他项目中没有。
