Question

To clarify, I’m relatively unfamiliar with Java.

I’m writing a class “GobblerClient” to interact with an API, and to test some of my functions I decided to write a few unit tests using JUnit. I’ve created a bunch of failing tests, and when I go to run them, it appears that JUnit just fails to find them.

Any ideas why JUnit might not be detecting my tests?

EDIT: The tests in full.

package com.gobbler;

import static org.junit.Assert.*;

import org.junit.Test;

public class GobblerClientTest {

    @Test
    public void testDisplay_name() {
        fail("Not yet implemented");
    }

    @Test
    public void testUser_id() {
        fail("Not yet implemented");
    }

    @Test
    public void testAuthenticity_token() {
        fail("Not yet implemented");
    }

    @Test
    public void testClient_key() {
        fail("Not yet implemented");
    }

    @Test
    public void testGobblerClient() {
        fail("Not yet implemented");
    }

    @Test
    public void testAuthenticate() {
        fail("Not yet implemented");
    }

    @Test
    public void testGet_data() {
        fail("Not yet implemented");
    }

    @Test
    public void testSha1hmac() {
        fail("Not yet implemented");
    }

}

The JUnit dialog is empty until you run some tests, it shows the results of the last run.

An easy way to do this is right-click on your class (either in the Package Explorer or the class name in your source code) and select Run As -> JUnit Test

If no tests appear at this point, try again with Run As -> Run Configurations... and in the Run dialog that appears ensure that the “Test runner” drop-down is set to “JUnit 4”. If it is set to an earlier version it will not detect your @Test annotations.

Edit: Since you are using Android rather than the standard JVM, you need to perform some additional setup, see my comments.
