結合 JUnit


結 合Ant與JUnit，可以讓你進行自動測試，最基本的方式可以執行org.junit.runner.JUnitCore來 進行測試。例如：
<project name="example" default="run"> 
    <property name="src.dir" value="src"/> 
    <property name="bin.dir" value="bin"/>
    <property name="junit.dir" value="lib/junit-4.8.2.jar"/>
    <property name="test.class" value=""/> 

    <target name="clean">
        <delete dir="${bin.dir}"/>
    </target>
    
    <target name="prepare" depends="clean"> 
        <mkdir dir="${bin.dir}"/> 
    </target> 

     <target name="compile" depends="prepare"> 
        <javac srcdir="${src.dir}" destdir="${bin.dir}">
            <classpath> 
                <pathelement location="${junit.dir}"/>  
            </classpath>           
        </javac>
    </target>

    <target name="run" depends="compile">
        <java classname="org.junit.runner.JUnitCore">
            <classpath path="${bin.dir};${junit.dir}"/>
	        <arg value="${test.class}"/>
        </java>
    </target>
</project>


在執行時，可以指定測試類別。例如：
>ant -Dtest.class=cc.openhome.CalculatorTest
Buildfile: C:\workspace\example\build.xml

clean:
   [delete] Deleting directory C:\workspace\example\bin

prepare:
    [mkdir] Created dir: C:\workspace\example\bin

compile:
    [javac] C:\workspace\example\build.xml:16: warning: 'includeantruntime' was not
 set, defaulting to build.sysclasspath=last; set to false for repeatable builds
    [javac] Compiling 2 source files to C:\workspace\example\bin

run:
     [java] JUnit version 4.8.2
     [java] ..
     [java] Time: 0.015
     [java]
     [java] OK (2 tests)
     [java]

你也可以使用<junit>標 籤，要使用這個標籤，Ant必須知道JUnit的JAR檔位置，你可以將JUnit的JAR檔放在Ant的lib目錄中，或者是於<junit>中使用 <classpath>指定。例如：
<project name="example" default="test"> 
    <property name="src.dir" value="src"/> 
    <property name="bin.dir" value="bin"/>
    <property name="junit.dir" value="lib/junit-4.8.2.jar"/>

    <target name="clean">
        <delete dir="${bin.dir}"/>
    </target>
    
    <target name="prepare" depends="clean"> 
        <mkdir dir="${bin.dir}"/> 
    </target> 

    <target name="compile" depends="prepare"> 
        <javac srcdir="${src.dir}" destdir="${bin.dir}"> 
            <classpath> 
                <pathelement location="${junit.dir}"/>  
            </classpath>        
        </javac>
    </target>
        	
    <target name="test" depends="compile"> 
        <junit printsummary="yes"> 
            <test name="cc.openhome.CalculatorTest"/> 
            <classpath> 
                <pathelement location="${bin.dir}"/>
                <pathelement location="${junit.dir}"/>  
            </classpath>
        </junit> 
    </target> 
</project>

執行時可以如下：
>ant
Buildfile: C:\workspace\example\build.xml

clean:
   [delete] Deleting directory C:\workspace\example\bin

prepare:
    [mkdir] Created dir: C:\workspace\example\bin

compile:
    [javac] C:\workspace\example\build.xml:16: warning: 'includeantruntime' was not
 set, defaulting to build.sysclasspath=last; set to false for repeatable builds
    [javac] Compiling 2 source files to C:\workspace\example\bin

test:
    [junit] Running cc.openhome.CalculatorTest
    [junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 0.028 sec

你可以在<junit>標 籤上指定其它屬性：
<junit printsummary="yes" haltonerror="yes" haltonfailure="yes" fork="yes">

haltonerror與haltonfailure如果設為yes，則在Error或Failure時，會中斷測試，fork如果為yes，則會為每個測試啟動一個新的JVM。

如果一次執行的測試類別不只一個，使用<test>指 定並不方便，則可以使用<batchtest>。 例如指定所有Test結尾的測試類別：
<project name="example" default="test"> 
    <property name="src.dir" value="src"/> 
    <property name="bin.dir" value="bin"/>
    <property name="junit.dir" value="lib/junit-4.8.2.jar"/>

    <target name="clean">
        <delete dir="${bin.dir}"/>
    </target>
    
    <target name="prepare" depends="clean"> 
        <mkdir dir="${bin.dir}"/> 
    </target> 

    <target name="compile" depends="prepare"> 
        <javac srcdir="${src.dir}" destdir="${bin.dir}"> 
            <classpath> 
                <pathelement location="${junit.dir}"/>
            </classpath>        
        </javac>
    </target>
        	
    <target name="test" depends="compile"> 
        <junit printsummary="yes"> 
            <batchtest>
                <fileset dir="${src.dir}" includes="**/*Test.java"/>
            </batchtest>
            <classpath> 
                <pathelement location="${bin.dir}"/>
                <pathelement location="${junit.dir}"/>  
            </classpath>
        </junit> 
    </target> 
</project>

執行時可以如下：
>ant
