依赖注入 – 使用Roboguice 2.0b3和Robolectric尝试使用RoboGuice.newDefaultRoboModule()进行单元测试和某些操作失败

我一直在看RoboGuice 2的astroboy示例代码和文档,老实说我很难过.我希望你们都可以帮我解决一些问题.这里的目标是测试模块以确保它正在加载并且IoC正在工作/接线.

我有一个类似于他们的例子的测试：
http://code.google.com/p/roboguice/source/browse/astroboy/src/test/java/org/roboguice/astroboy/controller/Astroboy2Test.java?name=roboguice-2.0b3&r=ba37ef680410c64f7f1fe90f5b7b482958d276b5

我的两种方式不同……我的模块在一个库类中,它的语法相同：

public class MyTestModule extends AbstractModule {
        @Override
        protected void configure() {
            bind(Vibrator.class).toInstance(vibratorMock);
        }
}

我还在值文件夹中的库类中有roboguice.xml

<resources> 
    <string-array name=roboguice_modules> 
        <item>com.yourdomain.MyTestModule</item> 
    </string-array> 
<resources>

测试项目引用app项目,该项目引用并导出库项目.

在测试项目中它是这样的：

@RunWith(RobolectricTestRunner.class)
public class MyTest {

    @Before
    public void setup() {
    // Override the default RoboGuice module
    RoboGuice.setBaseApplicationInjector(Robolectric.application,RoboGuice.DEFAULT_STAGE,Modules.override(RoboGuice.newDefaultRoboModule(Robolectric.application)).with(new MyTestModule()));
}

在设置过程中,它总是出现错误,带有某种空异常.我已经解决了这个问题,特别是newDefaultRoboModule方法.我知道Robolectric.application不是null,我知道新的MyTestModule也不是null.虽然在单步执行调试器时,我发现MyTestModule.binder为null,所以我不知道这是不是问题.

我还应该在哪儿看？我对通过测试所有这些结合感到迷茫.

谢谢你的期待,

我需要在我的roboguice 2.0设置中包含来自guice 3.0 zip的javax.inject.jar.
