I have no idea how to test and I was following a tutorial.I am trying to run:
package name.company.sunshine.app.data;
import android.test.AndroidTestCase;
just as Matt Accola sayd, if you already selected the gradle option and cant find that sub menu in his answer, u will need to go to run >> Edit Configuration... and then under the Gradle sub menu, delete the items (TestPractice & others if existed) and then re do the test by selecting the AnroidTest.
