Android 广播接收器单元测试 IntentAction 为空

如何解决Android 广播接收器单元测试 IntentAction 为空

我是 Android 新手，正在尝试测试广播接收器。 在下面的代码中，意图操作为空，它通过 NullPointerException。

    @Test
    public void TestAttachTimeoutIntent() {

        String intentAction = Constants.actionPrefix + Constants.actionAttach;
        Context mockContext = mock(Context.class);
        SgsLitebroadcastReceiver broadcastReceiver = new SgsLitebroadcastReceiver(null,null);

        Intent attachIntent = new Intent(intentAction);
        attachIntent.putExtra("result",RESULT_SUCCESS);
        attachIntent.putExtra("sequence_number",3);

        broadcastReceiver.onReceive(mockContext,attachIntent);
        assertNull(broadcastReceiver.getResultData());



        ArgumentCaptor<Intent> argumentIntent = ArgumentCaptor.forClass(Intent.class);
        Mockito.verify(mockContext,Mockito.times(1)).startActivity(argumentIntent.capture());


        Intent receivedIntent = argumentIntent.getValue();
        assertNull(receivedIntent.getAction());
        assertEquals("result",receivedIntent.getStringExtra("result"));
        assertTrue((receivedIntent.getIntExtra("sequence_number",0) != 0));
    }
