android - Robolectric 3 的图书馆资源 - JodaTime

Question

在 Robolectic 3.0-rc3 中使用库时出现 ResourceNotFoundException。该资源在 build.gradle 中声明为 compile 'net.danlew:android.joda:2.8.0'。具体来说，这是 Joda-Time 的 Android 端口。

android.content.res.Resources$NotFoundException: Unable to find resource ID #0x7f0501da
at org.robolectric.shadows.ShadowResources.checkResName(ShadowResources.java:343)
at org.robolectric.shadows.ShadowResources.getResName(ShadowResources.java:333)
at org.robolectric.shadows.ShadowResources.openRawResource(ShadowResources.java:382)

at net.danlew.android.joda.ResourceZoneInfoProvider.openResource(ResourceZoneInfoProvider.java:120)
at net.danlew.android.joda.ResourceZoneInfoProvider.<init>(ResourceZoneInfoProvider.java:39)

应用类:

@Override
public void onCreate() {
    super.onCreate();    
    JodaTime.init(this);
}

我的测试类:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,
    sdk = 21)
public class MyTest {

@Before
public void setup() {

}

@Test
public void myTest() {
//Test my stuff
}

Answer 1

您需要使用 Robolectric 运行时环境在测试中初始化库。所以将其添加到您的 setup() 方法中。

JodaTimeAndroid.init(RuntimeEnvironment.application);

所以你的测试看起来像这样:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 21)
public class MyApplicationTest {

    @Before
    public void setup() {
        JodaTimeAndroid.init(RuntimeEnvironment.application);
    }

    @Test
    public void myTest() {
        //Test my stuff
        DateTime aDateTime = new DateTime();
        DateTime bDateTime = new DateTime(aDateTime);
        assertEquals(aDateTime, bDateTime);
    }
}
