wiremock uiautomator

[João Prudêncio]

Hey I'm trying to setup a mock server in my ui automator test.

But I'm getting the following error:

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/impl/client/HttpClientBuilder;
at com.github.tomakehurst.wiremock.http.HttpClientFactory.createClient(HttpClientFactory.java:45)

Do you have any idea what the problem may be?

Have you tried the standalone JAR? This re-packages the Apache HTTP client, so you can avoid conflicts with other transitive dependencies.

I tried this and immediately hit the dex method limit. I'm not sure how Sam got this working w/out needing standalone: https://github.com/handstandsam/AndroidHttpMockingExamples/blob/master/app/build.gradle

If you include WireMock, you'll immediately hit the dex limit as there are a bunch of Apache libraries that come with it.  In the gradle file you linked to from my project, you need to enable multidexing to allow for it to run WireMock.

multiDexEnabled = true

I'm not sure if there is a way to ONLY enable multi-dexing for an androidTest compile, but if I understand correctly, if you have multi-dex enabled, but don't actually hit the dex limit, you'll still only use 1 dex file.  So, just monitor your method count and you should be okay to do it.

Using WireMock for our Espresso tests has been pretty awesome so far.  It has downsides (the dependencies), but worth it for the tests.  Read more about it here: http://handstandsam.com/2016/01/30/running-wiremock-on-android/

Cheers,

There isn't a way to only enable multi-dexing for androidTestCompile. But I like that idea: use multidex but keep app under limit so multidexing only happens on test apk.

Sam,

I'm finally coming back to this and I want to confirm something you said. You are running multidex on your app apk. By doing so it also multidexes your androidTest instrumentation test apk? This seems to contradict what's said here:

https://developer.android.com/studio/build/multidex.html#testing

"Note: Use of multidex for creating a test APK is not currently supported."

[Jason Atwood]

Holy crap. I just tested this and you're right!!!! I can start using Wiremock again.

 Man the documentation on developer.android.com needs to be updated to reflect this.
