我创建了一个TestModule类来注入一个测试实现类，并且它因classCastException而失败。
我正在使用Robolectric 2.4。
这是我通过自定义robolectric runner
创建的自定义TestApplicationpublic class AppApplicationTest extends MyApplication {
@Override
protected void attachBaseContext(Context base) {
configureModuleInjection();
System.out.println(this.getClass().getSimpleName() + " attached and initialised AppApplicationTest ");
try {
MultiDex.install(base);
super.attachBaseContext(base);
} catch (RuntimeException ignored) {
// Multidex support doesn't play well with Robolectric yet
System.out.println(this.getClass().getSimpleName() + " runtime exception = " + ignored.toString());
}
}
private void configureModuleInjection() {
//fails below with classCastException
RoboGuice.getOrCreateBaseApplicationInjector(this,
RoboGuice.DEFAULT_STAGE,
RoboGuice.newDefaultRoboModule(this),
new TestModule());
}
}
这是我自定义的RobolectricTestRunner
public class MyRoboTestRunner extends RobolectricTestRunner {
....
@Override
protected Class<? extends TestLifecycle> getTestLifecycleClass() {
return ApplicationTest.class;
}
public static class ApplicationTest extends DefaultTestLifecycle{
@Override
public Application createApplication(Method method, AndroidManifest appManifest, Config config) {
return new AppApplicationTest();
}
}
@Override
protected ClassLoader createRobolectricClassLoader(Setup setup, SdkConfig sdkConfig) {
return super.createRobolectricClassLoader(new ExtraShadows(setup), sdkConfig);
}
class ExtraShadows extends Setup{
private Setup setup;
public ExtraShadows(Setup setup) {
this.setup = setup;
}
@Override
public boolean shouldInstrument(ClassInfo classInfo) {
boolean shouldInstrument = setup.shouldInstrument(classInfo);
return shouldInstrument || classInfo.getName().equals(MultiDex.class.getName());
}
}
}
这是完整的堆栈跟踪错误

答案 0 :(得分：0)
因为这条线 java.lang.IllegalStateException：无法使用注释数据库
您可以尝试使用RoboGuice.setUseAnnotationDatabases（false）;
private void configureModuleInjection() {
RoboGuice.setUseAnnotationDatabases(false);
RoboGuice.getOrCreateBaseApplicationInjector(this,
RoboGuice.DEFAULT_STAGE,
RoboGuice.newDefaultRoboModule(this),
new TestModule());
}
