RxJava进行单元测试的方式

  @Test
    public void completeTask_retrievedTaskIsComplete() {
        // Given a new task in the persistent repository
        final Task newTask = new Task(TITLE, "");
        mLocalDataSource.saveTask(newTask);

        // When completed in the persistent repository
        mLocalDataSource.completeTask(newTask);

        // Then the task can be retrieved from the persistent repository and is complete
        TestSubscriber<Optional<Task>> testSubscriber = new TestSubscriber<>();
        mLocalDataSource.getTask(newTask.getId()).subscribe(testSubscriber);
        testSubscriber.assertValueCount(1);
        Task result = testSubscriber.values().get(0).get();
        assertThat(result.isCompleted(), is(true));
    }
