java - How to test an activity with robolectric while it has android.support.v7.widget.CardView? -
i have complex project contains few flavors , project dependency projects. if consider my_project project, contains project_1 main project, project_2 , project_3 acting dependency project_1. i've put tests under project_2/src/test/java.
i'm trying write few simple methods test splash screen based on.
this code have written:
package com.something.splash; import android.os.build; import android.view.view; import static org.junit.assert.assertnotnull; import static org.junit.assert.assertnull; import static org.junit.assert.asserttrue; import com.flavour_1.buildconfig; import com.flavour_1.r; import org.junit.assert; import org.junit.before; import org.junit.test; import org.junit.runner.runwith; import org.robolectric.robolectric; import org.robolectric.robolectricgradletestrunner; import org.robolectric.annotation.config; @runwith(robolectricgradletestrunner.class) @config(constants = buildconfig.class, sdk = build.version_codes.kitkat, manifest = "../project_1/src/main/androidmanifest.xml") public class splashactivitytest { private splashactivity msplashactivity; @test public void testme() { asserttrue(1 > 0); } @before public void setup() { this.msplashactivity = robolectric.buildactivity(splashactivity.class).create().get(); <==== problem } @test public void checkactivitynotnull() throws exception { assertnotnull("how come splashactivity null???", this.msplashactivity); } @test public void checkvisibilityofcardview() throws exception { view ivbranding = this.msplashactivity.findviewbyid(r.id.ivbranding); assert.assertequals(ivbranding.getvisibility(), view.visible); view cardview = this.msplashactivity.findviewbyid(r.id.splash_error_layout); assertnull("cardview must invisible default.", cardview); } } this output when run ./gradlew test command:

i have these lines in project_2 gradle file:
apply plugin: 'com.android.library' android androidconfiguration android { sourcesets { main { res.srcdirs = ['src/main/res', 'src/main/res-flags'] } } } dependencies { ... compile 'com.android.support:recyclerview-v7:22.1.1' compile 'com.android.support:cardview-v7:22.1.1' compile 'com.google.android.gms:play-services-gcm:7.3.0' compile 'com.google.android.gms:play-services-maps:7.3.0' // roboelectric testing testcompile 'junit:junit:4.12' testcompile 'org.robolectric:robolectric:3.0-rc3' }
okay, thing learnt 1 of bosses "when working on big project , face bug/problem/issue cannot fix (easily), try create new project in order replicate issue , fix on there first". having experience in mind, created new project , tried replicate issue. however, i'm happy that, it's working fine. compare , fix main project.
for how have same problem, have pushed sample project @ repo: https://github.com/hesamedin/robolectrictester/tree/master/app/src/test
hope helps.
