double espresso test with gradle - empty test suite - testing

Question

I'm trying to use espresso to test my aplication. As I found in other postes I shall use double espresso insted of pure espresso with gradle. Doulbe espresso can be found here: https://github.com/JakeWharton/double-espresso.
I configured a run configuration like this: http://wiki.android-test-kit.googlecode.com/git/android-studio-new-run-configuration.png. When I execute it, after a while it says Empty Test Suite
I created the following test class in androidTest/java directory:
package com.myapp.mobileapp.test.ui;
#LargeTest
public class LoginTest extends ActivityInstrumentationTestCase2<LoginActivity> {
public LoginTest(Class<LoginActivity> activityClass) {
super(activityClass);
}
#Override
public void setUp() throws Exception {
super.setUp();
getActivity();
}
#SmallTest
public void testLogin() {
onView(withId(R.id.buttonLogin))
.perform(click());
assertTrue(true);
}
}
My project has a top project that has the apk project and the facebook library project.
The build file for the top project is the following:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.11.+'
}
}
allprojects {
repositories {
mavenCentral()
}
}
the build file for the apk project is the following:
apply plugin: 'android'
android {
compileSdkVersion 18
buildToolsVersion "19.1.0"
// https://code.google.com/p/android/issues/detail?id=71147

Answer 1

You are probably getting an exception, so check the logs.
The constructor needs to be like this:
public LoginTest() {
super(LoginActivity.class);
}
