MockWebServer timeout issues

MockWebServer timeout issue

Since I have upgraded from 3.2.0 to 3.3.1, our CI has timed out while using the MockWebServer.

Code:

The test case is similar to: https://github.com/JakeWharton/retrofit1-okhttp3-client/blob/master/src/test/java/com/jakewharton/retrofit/Ok3ClientIntegrationTest.java#L23.

public final class ServiceTest {

    @Rule public final MockWebServer server = new MockWebServer();
    protected String mockEndPoint;

    @Before
    public void setUp() throws Exception {
        mockEndPoint = server.url("/").toString();
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testAcquireToken() {
        // Response
        final String mockResponse = "{\n" +
                "  \"access_token\": \"" + TOKEN_VALID + "\",\n" +
                "  \"refresh_token\": \"" + TOKEN_VALID + "\",\n" +
                "  \"token_type\": \"bearer\",\n" +
                "  \"expires_in\": 3600,\n" +
                "  \"logout_token\": \"r0ZZSZDVbUma9sTz0ZXduwvic1V7RdSIZMe\\/ysHTY8s=\"\n" +
                "}";

        server.enqueue(new MockResponse()
                .setResponseCode(HttpURLConnection.HTTP_OK)
                .setBody(mockResponse));

        // Request
        final Map<String, String> formData = new HashMap<>();
        formData.put("grant_type", "password");
        formData.put("client_id", "fake-id");
        formData.put("client_secret", "fake-secret");
        formData.put("username", "user EMAIL");
        formData.put("password", "user PASSWORD");

        final TokenResponse response = Service.getInstance(mockEndPoint)
                .acquireToken(formData)
                .toBlocking()
                .first();

        assertThat(response.getAccessToken()).isEqualTo("valid");
    }
}

Error:

Awww, that’s awkward. We’ve seen other problems with Robolectric, mostly around how OkHttp attempts to detect which platform it’s running on. Robolectric makes that very difficult because it looks like Android and the JVM simultaneously.

After playing with the dependencies, it seems that rolling back Robolectric to 3.1-rc1 from 3.1 seems to work fine:

    testCompile "org.robolectric:shadows-play-services:3.1-rc1"                         // Slowing down tests
    testCompile "org.robolectric:shadows-support-v4:3.1-rc1"                            // Slowing down tests
