如何将本地库路径添加到junit任务？ [英] How to add a native library path to the JUNIT task?

问题描述

我有一个使用串行通信这个驱动的Java项目。该驱动程序使用Windows下一个dll创建串行端口。

该项目包含完整的成功使用运行方式 - > JUnit测试几个JUnit测试。但是，引用本地库测试失败运行ant（这不引用本地库通测试）时。

我最好的猜测，到目前为止是添加包含本地库到的java.library.path目录，但我还没有成功地通过build.xml文件这样做。

有人可以告诉（干净）解决方案？

下面是我的build.xml：

 ＆LT;路径ID =compile.classpath＆GT;
    ＆LT;文件集DIR =$ {} lib目录＆GT;
        ＆LT;包括姓名=** / *罐子。/＆GT;
    ＆LT; /文件集＆GT;
    ＆LT;文件集DIR =$ {} JUNIT_HOME＆GT;
        ＆LT;包括姓名=** / *罐子。/＆GT;
    ＆LT; /文件集＆GT;
＆LT; /路径＆GT;＆所述;路径ID =test.classpath＆GT;
    ＆LT; pathelement位置=$ {}斌/＆GT;
    ＆LT;文件集DIR =$ {} lib目录＆GT;
         ＆LT;包括姓名=** / *罐子。/＆GT;
     ＆LT; /文件集＆GT;
    ＆LT;文件集DIR =$ {} JUNIT_HOME＆GT;
        ＆LT;包括姓名=** / *罐子。/＆GT;
    ＆LT; /文件集＆GT;

＆LT; /目标与GT;＆lt;目标名称=测试＆GT;

        ＆LT;类路径REFID =test.classpath/＆GT;
    ＆LT; / JUnit的＆GT;
＆LT; /目标与GT;
 

这里是测试报告（XML格式）的一部分：

解决方案

在蚂蚁的 junit任务，允许设置系统属性，就像一些其他任务。你需要指定在 sysproperty 嵌套元素作为的java.library.path 值：

 ＆LT; JUnit的叉=YESprintsummary =YEShaltonfailure =YES＆GT;
    ＆lt;试验NAME =$ {} test.class.nametodir =$ {} test.reports/＆GT;
    ＆LT;格式化类型=XML/＆GT;
    ＆LT;类路径REFID =test.classpath/＆GT;
    ＆LT; sysproperty键=的java.library.pathVALUE =把你的库路径在这里/＆GT;
＆LT; / JUnit的＆GT;
 

I have a Java project that uses this driver for serial communication. The driver uses a dll under Windows to create serial ports.

The project contains several JUnit tests which complete successfully using the "Run as -> JUnit Test". However, the tests referencing the native library fail when running ant (and tests that do not reference the native library pass).

My best guess so far is to add the directory that contains the native library to the java.library.path, but I haven't succeeded in doing so through the build.xml file.

Can somebody tell a (clean) solution?

Here is my build.xml:

<path id="compile.classpath">
    <fileset dir="${lib}">
        <include name="**/*.jar"/>
    </fileset>
    <fileset dir="${junit_home}">
        <include name="**/*.jar"/>
    </fileset>
</path>

<path id="test.classpath">
    <pathelement location="${bin}" />
    <fileset dir="${lib}">
         <include name="**/*.jar"/>
     </fileset>
    <fileset dir="${junit_home}">
        <include name="**/*.jar"/>
    </fileset>
</path>

<target name="compile">
    <mkdir dir="${bin}" />
    <echo Message="Compiling src folder..." />
    <javac includeantruntime="no" classpathref="compile.classpath" srcdir="${src}" destdir="${bin}" />
    <echo Message="Compiling test folder..." />
    <javac includeantruntime="no" classpathref="compile.classpath" srcdir="${test}" destdir="${bin}" />
</target>

<target name="test">
    <mkdir dir="${test.reports}" />
    <junit fork="yes" printsummary="yes" haltonfailure="yes">
        <test name="${test.class.name}" todir="${test.reports}" />
        <formatter type="xml" />
        <classpath refid="test.classpath" />
    </junit>
</target>

And here is a part of the test report (in XML):

解决方案

The junit task in Ant, allow setting system properties, just like some of the other tasks. You'll need to specify the java.library.path value in the sysproperty nested element as:

<junit fork="yes" printsummary="yes" haltonfailure="yes">
    <test name="${test.class.name}" todir="${test.reports}" />
    <formatter type="xml" />
    <classpath refid="test.classpath" />
    <sysproperty key="java.library.path" value="put your library path here"/>
</junit>
