Re: Does GWTTestCase still work?

When running from the command line, I forgot to add all the items to the class path.  Once I did that, I got the same error IntelliJ did:

There was 1 error:
1) testSimple(test.craig.MyTests)com.google.gwt.junit.JUnitFatalLaunchException: The test class 'test.craig.MyTests' was not found in module 'test.craig.App'; no compilation unit for that type was seen

I created a demo project with https://github.com/NaluKit/gwt-maven-springboot-archetype with the params:

- modular-springboot-webapp

- groupId: test.craig
- artifactId: testing
- module-short-name app: tc

Added JUnit to the client pom:

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.13.2</version>
  <scope>test</scope>
</dependency>

Created a simple test in the client module (in src/test/java/test/craig/MyTests.java):

public class MyTests extends GWTTestCase {
  @Override
  public String getModuleName() {
    return "test.craig.App";
  }
  public void testSimple() {
    assertTrue( true );
  }
}

Tried to run it in IntelliJ, but got the error:

com.google.gwt.junit.JUnitFatalLaunchException: The test class 'test.craig.MyTests' was not found in module 'test.craig.App'; no compilation unit for that type was seen

Tried to compile and run it from the command line:

java junit.textui.TestRunner test.craig.MyTests

But that returned:

Error: Could not find or load main class junit.textui.TestRunner
Caused by: java.lang.ClassNotFoundException: junit.textui.TestRunner

I thought I was following the instructions in https://www.gwtproject.org/doc/latest/DevGuideTesting.html but obviously doing something wrong.

Any help is much appreciated.
