How to do things

Change Code

• run IntelliJ's "migrate tests 4 -> 5"
• Check for Junit 3 TestCase and remove the extends part
• Annotate @Test by : Replace (by text) all public void test to @Test \n public void test
• Add imports by : Replace public class with import org.jun... Test \n import static Asssertions.*; \n public class

Validate

• search all public void test... and check Dups or missing(indents)
• search all public class... and check JavaDoc in between imports
• search and remove all org.junit.Assert
• search and remove Assert.*
• search all assertNotNull error message String usage

@cowtowncoder Could you open this one up again? I made a mistake above PRs resolve this.

Didn't know "partly resolves #xxx" would also do this 😅

[cowtowncoder]

Yeah, github is being too "smart". :-(

[cowtowncoder]

Completed, I think!
