Android setting up androidTestCompile

I am trying to setup up androidTests in an existing project.

Following the official guide by Google I added following dependencies:

    androidTestCompile 'junit:junit:4.12'
    androidTestCompile 'org.robolectric:robolectric:3.1.2'
    androidTestCompile 'org.assertj:assertj-core:3.5.2'
    androidTestCompile 'com.android.support:support-annotations:25.3.1'
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support.test:rules:0.5'
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3'

The first problem was, that there were multiple confilicting files (duplicates) within the APK:

packagingOptions {
        pickFirst '.readme'
        pickFirst 'META-INF/LICENSE.txt'
        pickFirst 'META-INF/plexus/components.xml'
        pickFirst 'META-INF/NOTICE.txt'
        pickFirst 'META-INF/MANIFEST.MF'
        pickFirst 'licenses/thoughtworks.TXT'
        pickFirst 'licenses/javolution.license.TXT'
        pickFirst 'licenses/extreme.indiana.edu.license.TXT'
        pickFirst 'org/apache/maven/project/pom-4.0.0.xml'
        pickFirst 'org/codehaus/plexus/plexus-bootstrap.xml'
        pickFirst 'org/cyberneko/html/res/HTMLlat1.properties'
        pickFirst 'org/cyberneko/html/res/HTMLsymbol.properties'
        pickFirst 'org/cyberneko/html/res/XMLbuiltin.properties'
        pickFirst 'org/cyberneko/html/res/HTMLspecial.properties'
        pickFirst 'org/cyberneko/html/res/ErrorMessages_ja.properties'
        pickFirst 'org/cyberneko/html/res/ErrorMessages.properties'
        pickFirst 'org/cyberneko/html/res/ErrorMessages_ja.txt'
        pickFirst 'org/cyberneko/html/res/ErrorMessages.txt'
        pickFirst 'META-INF/LICENSE'
        pickFirst 'META-INF/DEPENDENCIES'
    }

After excluding the duplicates, I ended up with ~1700 warning about classes, superclasses and interface which chould not be found, along with the error:

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForMediadeDebugAndroidTest'.
> Job failed, see logs for details

I really don't know at which parts to further look at,to make tests work.

EDIT: Here are the Gradle Logs

You need not run ProGuard while running tests, so you can remove the proguardFiles lines and change minifyEnabled to false.

EDIT

To get rid of duplicate dependencies, you need to check the Gradle Console logs to look for the lines about java.util.zip.ZipException: duplicate entry to find which classes are being added multiple times.

Once you know which classes are duplicated, you can fix it as explained here: Fixing ZipException: duplicate entry
