Why Am I getting no tests found?

Issue

When executing ./gradlew clean connectedAndroidTest with the following configuration... I'm getting No tests found

This is my build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.1'
        classpath 'com.github.jcandksolutions.gradle:android-unit-test:2.0.1'
    }
}

allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        jcenter()
    }
}

apply plugin: 'com.android.application'

This is the class for the tests under src/espressoTest:

package com.example;

import android.test.ActivityInstrumentationTestCase2;
import android.test.suitebuilder.annotation.LargeTest;

import com.betavalue.myvalue.MainActivity;
import com.betavalue.myvalue.R;

import static com.google.android.apps.common.testing.ui.espresso.Espresso.onView;
import static com.google.android.apps.common.testing.ui.espresso.assertion.ViewAssertions.matches;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withId;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withText;

@LargeTest
public class MainEspressoTest extends ActivityInstrumentationTestCase2<MainActivity> {

    @SuppressWarnings("deprecation")
     public MainEspressoTest() {
       // This constructor was deprecated - but we want to support lower API levels.
       super(MainActivity.class);
     }
    @Override
    public void setUp() throws Exception {
        super.setUp();
        // Espresso will not launch our activity for us, we must launch it via getActivity().
        getActivity();
    }

    public void testCheckText() {
        onView(withId(R.id.text))
            .check(matches(withText("Hello Espresso!")));
      }
}

And MainActivityis an empty Activity just to try testing.

Any ideas? Is there something on the AndroidManifest.xml I could be missing?

Solution

If anyone is having this issue... It just solved automatically when pulling it from my repository again.

It had to do something with Android Studio cache.
