gwt-test-utils ne parvient pas à exécuter des tests avec Ant

Question

J'ai créé un exemple de projet pour exécuter mes tests gwt avec gwt-test-utils (https://github.com/povilasb/gwt-test-utils-sample). J'utilise Ant (1.8.2) pour les builds, les paquets: gwt 2.6, juni 4.11 et gwt-test-utils 0.47.

Malheureusement, je ne parviennent pas à exécuter des tests:

html-test-utils-config:

Il semble que quelqu'un avait déjà cette question avant: https://code.google.com/p/gwt-test-utils/issues/detail?id=168. Impossible de trouver la solution là-bas.

Quelqu'un at-il eu de la chance avec gwt 2.6 et gwt-test-utils 4.7 et ant?

Answer 1

J'ai réussi à résoudre mon problème. J'éliminé l'erreur

Error while scanning package 'com.googlecode.gwt.test.internal.patchers'

En utilisant le mode fourche Antjunit tâche:

<junit haltonfailure="false" includeantruntime="false" 
    fork="yes" forkmode="once" > 

C'est le recommended method pour exécuter junit essais:

In general, forking a new VM is recommended since it isolates your test from Ant's environment (which contains a lot of libraries on the classloader, in particular XML related classes) but it becomes really slow because of the big overhead associated with starting new Java VMs.

Après cela, j'eu une autre erreur:

Et je résolu cette erreur en ajoutant répertoire de code source pour junit classpath:

<property name="src.dir" value="src" /> 
... 
<junit haltonfailure="false" includeantruntime="false" 
    fork="yes" forkmode="once" > 
    ... 
    <classpath> 
     <path refid="project.class.path" /> 
     <pathelement location="${test.build.dir}" /> 
     <pathelement location="${src.dir}" /> 
    </classpath> 

    ... 
</junit> 

je suppose que GWT-test-utils nécessaires sources du module GWT. Vous pouvez trouver un exemple de projet entièrement fonctionnel sur github.
