MockWebServer不等待N秒返回存根响应

Question

Android Espresso的测试：

第一版

export class AppComponent {
  constructor(private cartService: CartService) {

  }

  doSomething() {
     this.cartService.addItem();
  }
}

这里是结果日志：

import okhttp3.mockwebserver.MockResponse
import okhttp3.mockwebserver.MockWebServer

private lateinit var mockServer: MockWebServer

   @Rule
   @JvmField
   var tradersIntentTestRule = IntentsTestRule(TradersActivity::class.java, false, false)

@Before
    fun setup() {
        mockServer = MockWebServer()
        mockServer.start(8081)
        Debug.d(TAG, "setup_START")

}


@Test
    fun testMockServer() {
        Debug.d(TAG, "testMockServer_start")
        mockServer.enqueue(MockResponse()
                .setResponseCode(200)
                .setBodyDelay(10000, TimeUnit.MILLISECONDS)
                .setBody(FileUtil.getStringFromFile(context, randomTraderStubName.stubName)));
        Debug.d(TAG, "testMockServer_finish")
    }


    @After
    @Throws
    fun tearDown() {
        mockServer.shutdown()
}

，您会看到立即显示文本“ 05-31 18:10:52.327 D/com.myproject.activity.TradersActivityTest(10312): testMockServer_start 05-31 18:10:52.371 D/com.myproject.activity.TradersActivityTest(10312): testMockServer_finish ”。不用等10秒。

第二版：

testMockServer_finish

结果logcat：

 @Test
    fun testMockServer() {
        Debug.d(TAG, "testMockServer_start")
        tradersIntentTestRule.finishActivity()
        mockServer.enqueue(MockResponse()
                .setResponseCode(200)
                .setBodyDelay(10000, TimeUnit.MILLISECONDS)
                .setBody(FileUtil.getStringFromFile(context, randomTraderStubName.stubName)));
        tradersIntentTestRule.launchActivity(Intent())
        Debug.d(TAG, "testMockServer_finish")
}

，现在您可以看到文本“ 05-31 18:14:54.103 D/com.myproject.android.activity.TradersActivityTest(11689): testMockServer_start 05-31 18:15:04.322 D/com.myproject.android.activity.TradersActivityTest(11689): testMockServer_finish ”在10秒后显示

为什么在第一个版本中不等待10秒？
