我在Android Studio中使用Robolectric 3.0 RC3进行单元测试。每次运行测试时,我都会遇到ResourceNotFoundException
的问题。请帮助我解决这个问题。
build.gradle
dependencies {
testCompile 'junit:junit:4.12'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
testCompile 'org.mockito:mockito-core:1.9.5'
testCompile 'org.robolectric:robolectric:3.0-rc3'
compile 'com.ibm.icu:icu4j:53.1'
}
测试类
@Before
public void setUp() throws Exception {
activity = Robolectric.buildActivity(MainActivity.class).create().get();
}
@Test
public void pressingTheButtonShouldStartTheListActivity() throws Exception {
//Something to test
}
那么,无论何时调用Robolectric.buildActivity()
,我都会收到Resources$NotFoundException
。资源#0x7f040016
指向R.layout.activity_main
(xml)。以下是堆栈跟踪-

MainActivity.java:15 表示设置内容视图为 setContentView(R.layout.activity_main);
MainActivityTest.java:32 表示创建并获取MainActivity的实例,使用Robolectric测试框架的语法为activity = Robolectric.buildActivity(MainActivity.class).create().get();
RobolectricGradleTestRunner
代替RobolectricTestRunner
,这应该可以解决你的问题。 - nenick
