Re: Does GWTTestCase still work?

Apologies.  Doing a mvn package does work.  The tests run successfully.  Doing a mvn test does not work (gives the "No source code is available for type test.craig.FieldVerifier; did you forget to inherit a required module?"" error).

Some extra (strange) behaviours:

Creating a class in the client module:

public class FieldVerifierOverride extends FieldVerifier { }

And then calling the test with this class:

assertTrue( FieldVerifierOverride.isValidName("hi") );

Gives a different error:

[ERROR] Could not find test.craig.FieldVerifier in types compiled from source. Is the source glob too strict?

Also, if I run mvn package (instead of mvn test), then the test actally runs, but FieldVerifier.isValidName("hi") returns false (it should return true):

  [ERROR] test.craig.MyTests.testSimple -- Time elapsed: 8.016 s <<< FAILURE!
  junit.framework.AssertionFailedError: expected: <true>, actual: <false>

In the GWTTestCase client tests, if I want to test code that's in the shared module.  Eg:

assertTrue( FieldVerifier.isValidName("hi") );

I get the error:

[ERROR] Line 13: No source code is available for type test.craig.FieldVerifier; did you forget to inherit a required module?

How can I inherit the shared module for the GWTTestCase tests?

Thanks Colin.  I wasn't aware of the "Suite" naming convention.

So, to summarise.  Either:

- Put "Suite" or "SuiteNoBrowser" at the end of the test class name, or

- Add the test class directly as an include in the client pom.xml, in the gwt-maven-plugin.

Now working great!

When using maven, running from the command line should be "mvn test". With the plugin you are using, it is assumed you are using a test suite - this is not required, but scales better. If you only need to run a single test, you can modify this includes.

https://tbroyer.github.io/gwt-maven-plugin/test-mojo.html#includes

For example in your project with MyTests (note: that wouldn't run even in a non-gwt project from maven, the default pattern is *Test), you could add this:
          <includes>
            <include>test/craig/MyTests.java</include>
          </includes>

When I do that, having built the sample as you describe, the tests passes with mvn test:
[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO] Running test.craig.MyTests
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 13.96 s -- in test.craig.MyTests

[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

When running from IJ, it doesnt automatically add sources to the classpath as gwt:test does, so you may just want to call the maven goal directly instead. I recall that it is possible to configure Maven/IJ to run tests "normally", but can't quickly spot what that would be.

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.
