调用Robolectric.buildActivity()时出现Resources $ NotFoundException [英] Resources$NotFoundException when calling Robolectric.buildActivity()

问题描述

我正在使用Robolectric 3.0 RC3在Android Studio中进行单元测试.每次运行测试时，我都会得到一个ResourceNotFoundException.请帮助我解决问题.

I am using Robolectric 3.0 RC3 for unit testing in Android Studio. And I am getting a ResourceNotFoundException every time I run the test. Please help me resolve the issue.

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
}

所以，每当Robolectric.buildActivity()我得到Resources$NotFoundException时.资源#0x7f040016指向R.layout.activity_main(xml).在id之后的堆栈跟踪-

So, whenever Robolectric.buildActivity() I get the Resources$NotFoundException. Resource #0x7f040016 points to R.layout.activity_main(xml). Following id the stack trace-

Process finished with exit code -1

MainActivity.java:15 是setContentView(R.layout.activity_main);

MainActivityTest.java:32 是activity = Robolectric.buildActivity(MainActivity.class).create().get();

推荐答案

您的测试类是否正确注释?是否使用了清单文件的正确路径? 以下对我有用:

Is your test class annotated correctly? And is it using the correct path to a manifest file? The following works for me:

@RunWith(RobolectricTestRunner.class)
@Config(manifest = "src/main/AndroidManifest.xml", emulateSdk = Build.VERSION_CODES.LOLLIPOP)
public class MyActivityTest { .... }

删除Config批注会导致您提到的ResourcesNotFound异常.

Removing the Config annotation causes the ResourcesNotFound exception you mentioned.
