如何为包含RxJava/RxAndroid的ViewModel编写单元测试

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;
import io.reactivex.observers.TestObserver;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

public class MyViewModelTest {

    @Mock
    private MyRepository mockRepository;

    private MyViewModel viewModel;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        viewModel = new MyViewModel(mockRepository);
    }

    @Test
    public void testGetData() {
        // 创建模拟的观察者
        TestObserver<String> testObserver = new TestObserver<>();

        // 使用模拟的RxJava调度器
        viewModel.setScheduler(Schedulers.trampoline());

        // 模拟Repository返回数据
        String data = "Test Data";
        Mockito.when(mockRepository.getData()).thenReturn(Observable.just(data));

        // 调用被测试的方法
        viewModel.getData().subscribe(testObserver);

        // 验证结果
        testObserver.assertComplete();
        testObserver.assertValue(data);
    }
}
