Ant PDE测试使用JUnit4运行

时间：2009-11-21 00:09:05

标签： ant junit4 pde

我正在尝试使用pde-maven-plugin，maven调用或ant任务自动化pde测试。我按照文章Automating Eclipse PDE Unit Tests using Ant中的说明创建了test.xml

测试失败，首先是因为没有找到测试

junit.framework.AssertionFailedError: junit.framework.AssertionFailedError: No tests found in com.example.TestSuite
    at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130)
    at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)

我搜索并发现我应该使用JUnit4Adapter，但这样做我得到ClassCastException，这是堆栈跟踪

java.lang.ClassCastException: junit.framework.JUnit4TestAdapter cannot be cast to junit.framework.Test

这是我的插件依赖项：

Require-Bundle: 
 org.eclipse.ui,
 org.eclipse.core.runtime,
 org.eclipse.jdt.core;bundle-version="3.4.2",
 org.eclipse.jdt.launching;bundle-version="3.4.1",
 org.eclipse.core.resources;bundle-version="3.4.1",
 org.apache.xerces;bundle-version="2.9.0",
 org.junit4;bundle-version="4.3.1"

和测试类

package com.example;

import junit.framework.JUnit4TestAdapter;
import junit.framework.Test;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses( { SimpleTests.class})
public class TestSuite {

    public static Test suite() {

        return new JUnit4TestAdapter(TestSuite.class);
    }

}

任何想法如何解决？

通过在调用org.eclipse.equinox.launcher.Main时添加下一行来修复：

<arg line="-testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader"/>
<arg line="-loaderpluginname org.eclipse.jdt.junit4.runtime"/>

这是完整的java ant任务：

<java dir="${plugin.dir}"  
    fork="yes"
    classname="org.eclipse.equinox.launcher.Main"
    classpathref="equinox.launcher.class.path"
    jvm="${jvm}">
    <arg line="-application ${application}"/>
    <arg line="-data ${test.reports.dir}/output/ws"/>
    <arg line="-port ${pde.test.port}"/>
    <arg line="-dev bin -clean -debug"/>
    <arg line="-testpluginname ${plugin.name}"/>
    <arg line="-testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader"/>
    <arg line="-loaderpluginname org.eclipse.jdt.junit4.runtime"/>
    <arg line="-classnames ${test.classes.list}"/>
    <jvmarg line="${vmargs}"/>
</java>

我和Noura有同样的问题并尝试了他们提供的解决方案，遗憾的是，这只解决了部分问题。尽管我使用ClassCastException仔细注释了29个测试，但我没有抛出前面提到的junit4 java.lang.Exception: No runnable methods，而是@Test。

经过几个小时的搜索（只有当JUnit 4是新的时才找到真正的老错误）和实验（this SO post也没有帮助），我发现我修复的第二部分是相关的到班级路径。

我已经定义了我的类路径（用于启动PDETestResultsCollector，PDETestPortLocator和测试插件）：

<path id="test.class.path">
   <pathelement location="build/my-bundled-jar-with-tests.jar" /> <!-- contains my app and the PDE* helper classes -->
   <fileset dir="${test.eclipse.dir}/plugins">
      <include name="org.junit_4.*/**/junit.jar" />
      <include name="org.hamcrest.core_*.jar" />
      <include name="org.apache.ant_*/**/ant.jar" />
      <include name="org.apache.ant_*/**/ant-junit.jar" />
      <include name="org.eclipse.jdt.core_*.jar" />
      <include name="org.eclipse.jdt.junit_*.jar" />
      <include name="org.eclipse.jdt.junit.core_*.jar" />
      <include name="org.eclipse.equinox.common_*.jar" />
      <include name="org.eclipse.debug.core_*.jar" />
      <include name="org.eclipse.osgi_*.jar" />
      <include name="org.eclipse.core.resources_*.jar" />
      <include name="org.eclipse.core.runtime_*.jar" />
      <include name="org.eclipse.core.jobs_*.jar" />
      <include name="org.eclipse.ui.workbench_*.jar" />
      <include name="org.eclipse.swt_*.jar" />
      <include name="org.eclipse.equinox.preferences_*.jar" />
      <include name="org.eclipse.equinox.launcher_*.jar" />
   </fileset>
</path>

并启动它：

<java classpathref="test.class.path" classname="org.eclipse.equinox.launcher.Main" fork="yes" dir="${basedir}" >
   <arg line="-application org.eclipse.pde.junit.runtime.uitestapplication" />
   <arg line="-data reports/output/ws" />
   <arg line="-dev bin -clean -port ${pde.test.port}" />
   <arg line="-testApplication org.eclipse.ui.ide.workbench" />
   <arg line="-testpluginname my-bundled-plugin-with-tests" />
   <arg line="-testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader" />
   <arg line="-loaderpluginname org.eclipse.jdt.junit4.runtime" />
   <arg line="-classnames TestAllMyCode" />
</java>

事实证明，在类路径上让build/my-bundled-jar-with-tests.jar混淆了测试运行器，所以我不得不制作一个新的jar，其中只包含PDETestListener，PDETestPortLocator和{{的类文件1}}（称为pde-test.jar）。我的固定路径是：

PDETestResultsCollector

所有29项测试都被发现并运行。
