Want to use JUnit in Domino Designer / Java Beans - but keep getting a "Class not found" error?

Question

I do the following:

1. From the Package Explorer I select "New, Other, JUnit Test Case"

2. I write this code:

   package dk.sample;
   
   import org.junit.*;
   import static org.junit.Assert.*;
   
   public class TestCase {
   
       @Test
       public void alwaysTrue(){
           assertTrue( true );
       }
   
   }
   

3. I then select "Run As, JUnit test"

4. Get this error: "Class not found dk.sample.TestCase java.lang.ClassNotFoundException: ...."

What do I miss? Have tried with different Run Configurations - but it seems like I miss a classpath somewhere? But to what and where?

Answer 1

To make JUnit work within Domino Designer you need to perform few additional steps:

1. set up source control for your application
2. adjust the on-disk project to be recognized as Java application
3. run JUnit tests within your on-disk project

Please note that java agents have to be tested in a different way..

You can find more detailed explanation about enabling JUnit for both XPages and Agents in the following blog post: Unit Tests for Lotus Domino Applications

Here's also a great how-to on this topic.

Answer 2

Coundn't get JUnit to work inside the Domino Designer. Instead of running the tests from DDE, I now run the tests from a XPages. This works like a dream. Made my own 'JUnit runner' class - that is, I just call the JUnit runners but handles the result my self in order to display it as html on the XPage.
