WireMock, Android: java.lang.NoClassDefFoundError

[Alexei J]

Android Studio 2.3.1, Android 7.0

My buld.gradle

android {

    compileSdkVersion 23

    buildToolsVersion "23.0.3"

    defaultConfig {

        minSdkVersion 15

        targetSdkVersion 23

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        multiDexEnabled = true

}

dependencies {

    testCompile 'junit:junit:4.12'

    testCompile 'org.powermock:powermock-api-mockito:1.6.6'

    testCompile 'org.powermock:powermock-module-junit4:1.6.6'

    testCompile "org.mockito:mockito-core:+"

    // for folder "androidTest"

    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'

    androidTestCompile "org.mockito:mockito-android:2.7.21"

    androidTestCompile "org.powermock:powermock-api-mockito:1.6.6"

    androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6'

    //WireMock

    androidTestCompile("com.github.tomakehurst:wiremock:2.6.0") {

        exclude group: 'org.apache.httpcomponents', module: 'httpclient'

        exclude group: 'org.ow2.asm', module: 'asm'

        exclude group: 'org.json', module: 'json'

    }

    androidTestCompile('com.squareup.okhttp3:mockwebserver:3.5.0') {

        exclude module: 'okhttp'

    }

}

My instrumented test (in folder "androidTest")  with WireMock:

public class WireMockApplicationTestCase2 {

    Logger logger = LoggerFactory.getLogger(WireMockApplicationTestCase2.class);

    WireMockServer wireMockServer;

    @Rule

    public ActivityTestRule<MainActivity> activityRule = new ActivityTestRule<>(MainActivity.class);

    private Context androidTestContext;

    private Context applicationContext;

    @Before

    public void setUp() throws Exception {

        this.androidTestContext = InstrumentationRegistry.getContext();

        this.applicationContext = InstrumentationRegistry.getTargetContext().getApplicationContext();

        wireMockServer = new WireMockServer(8089);

        wireMockServer.start();

    }

     @Test

    public void testWiremockPlusOkHttp() throws IOException {

        logger.debug("testWiremockPlusOkHttp");

        String serviceEndpoint = "http://127.0.0.1:" + 8089;

        logger.debug("WireMock Endpoint: " + serviceEndpoint);

        OkHttpClient okHttpClient = // some code fot http client;

        String uri = "/hello-world";

        Request request = new Request.Builder()

                .url(serviceEndpoint + uri)

                .build();

        Response response = okHttpClient.newCall(request).execute();

        String responseBodyStr = response.body().string();

        logger.debug("Response Body: " + responseBodyStr);

        assertEquals("hello world", responseBodyStr);

    }

}




But when I start this test (Android 7.0) I get error:

I found solutions of problem:

If you use Android 5.0- (e.g. Android 4.3) then you MUST use Wiremock version 2.0.8-beta

androidTestCompile 'com.github.tomakehurst:wiremock:2.0.8-beta'

If you use Android 5.0+ you can you use any Wiremock version (e.g. 2.5.0)

androidTestCompile 'com.github.tomakehurst:wiremock:2.6.0'

P.S. Maybe this is a Multidex issues.
