MockWebServer

Question

当我开始测试时出现连接异常，我不知道为什么。

我找到了一些其他作者的代码并比较了代码，我没有发现任何错误。我尝试更改端口或将其删除，但没有帮助。

@RunWith(AndroidJUnit4::class)
class RideFragmentTest {

@get:Rule
    val activityRule: ActivityTestRule<MainActivity> = ActivityTestRule(MainActivity::class.java)
    private val mockWebServer = MockWebServer()
    private val PORT = 8607

@Before
    fun init() {
        mockWebServer.start(PORT)
        routeToFragment()
    }

@After
    fun finish() {
        mockWebServer.shutdown()
    }

@Test
    fun someTest() {
        val dispatcher = object : Dispatcher() {
            @Throws(InterruptedException::class)
            override fun dispatch(request: RecordedRequest): MockResponse {
                when (request.path) {
                    "/something/current" -> {
                        val jsonBody = asset(activityRule.activity, "something.json")
                        return MockResponse().setResponseCode(200).setBody(jsonBody)
                    }
                    "/something/save" -> {
                        return MockResponse().setResponseCode(200)
                    }
                }
                return MockResponse().setResponseCode(404)
            }
        }
        mockWebServer.dispatcher = dispatcher

        assertDisplayed(..., ...)
    }
}

D/OkHttp: --> GET http://127.0.0.1:8607/something/current
D/OkHttp: --> END GET
HTTP FAILED: java.net.ConnectException: Failed to connect to /127.0.0.1:8607

我没有发现任何奇怪的日志。

我解决了我的问题。

我的代码应该是这样的：

@RunWith(AndroidJUnit4::class)
class RideFragmentTest {

private val fragment = RideFragment.newInstance()

@get:Rule
    val activityRule: ActivityTestRule<MainActivity> = ActivityTestRule(MainActivity::class.java)
    private val mockWebServer = MockWebServer()
    private val PORT = 8607

@Before
    fun init() {
        mockWebServer.start(PORT)
    }

@After
    fun finish() {
        mockWebServer.shutdown()
    }

@Test
    fun someTest() {
        val dispatcher = code above..
        mockWebServer.dispatcher = dispatcher
        routeToFragment()

        assertDisplayed(..., ...)
    }

    private fun routeToFragment() = activityRule
       .activity
       .supportFragmentManager
       .beginTransaction()
       .replace(R.id.container, fragment)
       .commit()
}

即我必须在设置调度程序后路由我的片段，因为 mockwebserver 没有时间进行初始化（我是这样理解的）。
