Using GoogleInstrumentationTestRunner in multidex project #106

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. enable multidex - http://developer.android.com/tools/building/multidex.html
2. run a ActivityInstrumentationTestCase2 with GoogleInstrumentationTestRunner

What is the expected output? What do you see instead?

Expect tests to run. 
Actual: Instrumentation run failed due to 'java.lang.NoClassDefFoundError'

What version of the product are you using? On what operating system?

espresso-1.1 on osx

Please provide any additional information below.

MultiDex support for tests requires the MultiDexTestRunner. Espresso requires 
the GoogleInstrumentationTestRunner. Do I need an implementation that merges 
both?

The MultiDexTestRunner thing is not really a problem. It only has a single line 
to call `MultiDex.install(getTargetContext())` - so I can just extend 
GoogleInstrumentationTestRunner and add that line to onCreate.

However, the NoClassDefException still exists. Logcat provides more info:

E/AndroidRuntime﹕ FATAL EXCEPTION: main
    java.lang.NoClassDefFoundError: com.google.android.apps.common.testing.testrunner.UsageTracker$NoOpUsageTracker

I'm using Espresso 2 as well. I implemented a custom runner that extends the 
new AndroidJUnitRunner and calls MultiDex.install(getTargetContext()) in 
onCreate(Bundle args). Further; I'm using a custom Application class that 
extends MultiDexApplication in my app.

Logcat output:
dalvikvm﹕ Class resolved by unexpected DEX: 
[Landroid/support/multidex/MultiDexApplication;] 
/dalvikvm﹕ (Lde/epost/abcapp/ABCApplication; had used a different 
Landroid/support/multidex/MultiDexApplication; during pre-verification)

Hi, the problem with "java.lang.IllegalAccessError: Class ref in pre-verified 
class resolved to unexpected implementation" is usually due to duplicate 
dependencies.

I have the current configuration that is "running" at least:
   ... 
   androidTestCompile('com.android.support.test.espresso:espresso-core:2.0') { 
        exclude group: 'com.google.guava' 
    }
    androidTestCompile('com.android.support.test:testing-support-lib:0.1') { 
        exclude group: 'com.google.guava' 
    }
    testingCompile ('com.android.support.test.espresso:espresso-contrib:2.0') {
        exclude group: 'com.google.guava'
        exclude group: 'javax.inject'
    }

The following question in SO ( 
http://stackoverflow.com/questions/25434099/running-tests-using-gradle-or-inside
-android-studio-result-in-noclassdeffounderr) addresses this issue. The 
accepted answer helped a lot having a working version with espresso 2 using 
multidex for api14+.

GITR is deprectated in favor of AndroidJunitRunner. If you're still having 
issues with AJUR, please open a new bug.
