Added separate proguard file for tests using testingProguardFile fixed

Can you post the test proguard file please?

would also be interested in this - the only result googling for testingProguardFile is here - https://xkcd.com/979/

Hi Guys, i get a solution for your problems.

First of all use testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.txt' in your debug configuration.

Use the following lines in the testProguard:

# ------------------- TEST DEPENDENCIES -------------------
-dontwarn org.hamcrest.**
-dontwarn android.test.**
-dontwarn android.support.test.**

-keep class org.hamcrest.** {
   *;
}

-keep class org.junit.** { *; }
-dontwarn org.junit.**

-keep class junit.** { *; }
-dontwarn junit.**

-keep class sun.misc.** { *; }
-dontwarn sun.misc.**

@rzetzsche thanks for that
one more line was necessary for me:
-dontwarn com.squareup.javawriter.JavaWriter
