蚂蚁PDE测试运行与化成junit4

Question

我试图自动化pde测试、使用pde-玛文件,家的呼吁，或蚂蚁的任务。我跟着指示，从文章 自动化蚀PDE单元测试使用蚂蚁 创造的test.xml

测试失败，首先因为没有测试发现

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，找到了，我应该使用 JUnit4Adapter, 但这样做，我得到了 ClassCastException, 这是堆叠跟踪

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

这是我的插件的相关性：

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);
    }

}

任何想法怎么解决？

Answer 1

它是通过将下一行调用时org.eclipse.equinox.launcher.Main固定：

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

下面是完整的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>    

Answer 2

我有同样的问题，作为努拉和试图解决他们提供的，其中，不幸的是，只有解决问题的一部分。而不是扔前述 ClassCastException, 我 junit4 java.lang.Exception: No runnable methods, 尽管我的29测试，正在仔细注释 @Test.

几个小时后搜索(并且只找到真正的老虫背当JUnit4新)和试验(这个以后 没有帮助)，我发现的第二部分我修复有关的类的道路。

我确定了我的类路径(这是用来启动 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>

并发起了这样的：

<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，具有 build/my-bundled-jar-with-tests.jar 在类路径混淆的测试运，所以我不得不让一个新的罐子，包含的只是类文件 PDETestListener, PDETestPortLocator 和 PDETestResultsCollector (称为pde-test.jar).我固定的路径是：

<path id="test.class.path">
   <pathelement location="build/pde-test.jar" /> <!-- fixed the problem -->
   <fileset dir="${test.eclipse.dir}/plugins">
      <include name="org.junit_4.*/**/junit.jar" />
      <include name="org.hamcrest.core_*.jar" />
      ... <!-- same as before -->

和所有29个测试中被发现和运行。
