android JUnit Tests not running

Question

The problem is not that the tests are failing, but that they simply do not run at all. That is to say, the console tells me they run, but I see absolutely no results from them at all.

Note that I 'have' remembered to annotate methods with @Test

Here's the code for the test class:

package module.jakway.JournalEntry.test;


import module.jakway.JournalEntry.Module_JournalEntry;

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class MainTest extends android.test.ActivityInstrumentationTestCase2<Module_JournalEntry>
{

    public MainTest(Class activityClass) {
        super("module.jakway.JournalEntry", Module_JournalEntry.class);
        // TODO Auto-generated constructor stub
    }

    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
    }

    @AfterClass
    public static void tearDownAfterClass() throws Exception {
    }

    @Before
    public void setUp() throws Exception {
        super.setUp();

        Module_JournalEntry journalentry = getActivity();

        assertTrue(true);
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void myTestCase()
    {
        assertTrue(false);
    }

}

The project I'm testing is named Module_JournalEntry with package module.jakway.JournalEntry and Activity Module_JournalEntry.java

Here's the console output:

Thanks very much!

Answer 1

Android bases its testing framework on JUnit 3 which doesn't use annotations but reflection and test method names should include the test prefix.

Move to JUnit 3 and run your tests from Eclipse as Run As -> Android JUnit Test or using am instrument from command line.

Answer 2

Try changing this:

public MainTest(Class activityClass) {
    super("module.jakway.JournalEntry", Module_JournalEntry.class);
    // TODO Auto-generated constructor stub
}

To this:

public MainTest() {
    super("module.jakway.JournalEntry", Module_JournalEntry.class);
    // TODO Auto-generated constructor stub
}

The constructor should have no parameters in this case. It's written in the Hello, Testing tutorial example under the Adding the test case constructor section.
