我根本无法成功运行 GWTTestCase 测试。我正在使用 GWT 2.6.1、JUnit 4.11、ant 1.8.2。我创建了示例 repository on github .

Ant 目标运行测试(也许这里很明显):

<target name="test.gwt" depends="javac.test"
description="Run GWTTestCase tests." >
<junit haltonfailure="false" includeantruntime="false">
<sysproperty key="gwt.args" value="-prod -runStyle
HtmlUnit" />
<sysproperty key="gwt.persistentunitcachedir"
value="${gwt.cache.dir}" />

<classpath>
<pathelement location="${src.dir}" />
<pathelement location="${test.build.dir}" />
<path refid="project.class.path" />
</classpath>
<formatter type="brief" usefile="false" />

<test name="com.example.client.TestPerson" />
</junit>
</target>

我使用 ant test.gwt 运行测试,得到的输出是:

test.gwt:

你知道我可能做错了什么吗?我也尝试过 JUnit 3.8 - 没有帮助。可能缺少 .*jar 文件或版本不正确?

最佳答案

好的,我成功地使用 Ant 运行了 GWTTestCase 测试。示例项目位于 github .

首先我切换到junit任务 fork 模式。其中,如documentation说,

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.

然后,当我添加 validation-api 包 (ivy.xml):

<dependency org="javax.validation" name="validation-api" rev="1.0.0.GA" />

然后很明显,我的测试缺少 GWT 模块。所以我创建了一个(./test/com/example/MainTests.xml.gwt):

<module rename-to="MainTests" >
<inherits name="com.example.Main" />
<source path="client" />
</module>

最终我必须将测试模块路径添加到测试类路径(build.xml):

<property name="test.src.dir" value="test" />
...
<junit haltonfailure="false" includeantruntime="false"
fork="true" forkmode="once" >

<classpath>
...
<pathelement location="${test.src.dir}" />
...
</classpath>
</junit>
