Unit teting using GWTTestCase

[Vish]

I am getting following error when I tried to test using GWTTestCases.

com.google.gwt.junit.JUnitFatalLaunchException: The test class
'com.abc.myapp.client.MyAppTestCase' was not found in module
'com.abc.myapp.Myapp'; no compilation unit for that type was seen

Here is the test class source code.

package com.abc.myapp.client;

import org.junit.Assert;
import com.google.gwt.junit.client.GWTTestCase;

public class MyAppTestCase extends GWTTestCase {
@Override
public String getModuleName() {
return "com.abc.myapp.Myapp";
}

public void testX(){
Assert.assertTrue(true);
}
}

In eclispe I am using following set up, it is as per maven standard.
src/main/java for which output folder is target/classes
src/main/resources for which output folder is target/classes
src/main/webapp
src/test/java for which output folder is target/test-
classes
src/test/resources for which output folder is target/test-
classes

Let me know if I am missing anything else.

FYI!, I am using GWT 2.3.

Thanks,

Vish

Is src/test/java (and src/test/resources) part of the buildpath/classpath for your JUnit launch? Not only the *.class has to be in the classpath, the *.java too.

[Vish]

I think it is already in place. refer here.

<classpathentry kind="src" output="target/test-classes" path="src/test/
resources"/>
<classpathentry kind="src" output="target/test-classes" path="src/test/
java"/>
<classpathentry kind="src" output="target/classes" path="src/main/
resources"/>
<classpathentry kind="src" output="target/classes" path="src/main/
java"/>

Does eclispe need GWT plug-in to run this?

[Thomas Broyer]

Are you launching your unit test using Run As… → GWT JUnit Test ? Otherwise, Eclipse does not automatically add source folders to classpath of your launchers (aka "Run/Debug configurations").
