Use @Test annotation and ActivityTestRule with Robotium (Espresso-way)
<p>I wonder how can i mark my test as @Test like in JUnit, because so far I have to use 'test...' name. It means:</p>

<pre><code>@Test
private void creatingAcc(){
</code></pre>

<p>instead of</p>

<pre><code>private void testCreatingAcc(){
</code></pre>

<p>Thanks in advance</p>
