一. 使用Junit进行測试
1. Java业务代码:
public class HelloWorld {
// 測试返回"world"
public String hello() {
return "world";
}
// 測试返回"hello"
public String world() {
return "hello";
}
// 測试为空
public String nil() {
return null;
}
// 測试不为空
public String notNil() {
return "abc";
}
// 測试抛出异常
public String ext() {
return null;
}
}2. 使用junit3測试, 继承TestCase
import junit.framework.TestCase;
public class HelloWorldTest extends TestCase {
private HelloWorld helloWorld; @Override
protected void setUp() throws Exception {
helloWorld = new HelloWorld();
System.out.println("helloWorld init");
} public void testHello() {
String str = helloWorld.hello();
assertEquals("測试world失败", str, "world");
} public void testWorld() {
String str = helloWorld.world();
assertEquals("測试world失败", str, "hello");
} public void testNotNil() {
assertNotNull("对象为空", helloWorld.notNil());
} public void testNil() {
assertNull("对象不为空", helloWorld.nil());
} public void testExt() {
try {
helloWorld.ext();
fail("没有抛出异常");
} catch (NumberFormatException e) {
}
} @Override
protected void tearDown() throws Exception {
System.out.println("hello world destory");
helloWorld = null;
}
}
3. 使用junit4測试, 使用注解
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*; // 静态引入, assertEquals兼容junit3
public class HelloWorldTest {
private HelloWorld helloWorld; @Before
public void setUp() {
helloWorld = new HelloWorld();
} @Test
public void testHello() {
String str = helloWorld.hello();
assertEquals("hello測试失败",str,"world");
} @Test
public void testWorld() {
String str = helloWorld.world();
assertEquals("world測试失败",str, "hello");
} @Test
public void testNil() {
assertNull("对象不为空",helloWorld.nil());
} @Test
public void testNotNil() {
assertNotNull("对象为空", helloWorld.notNil());
} @Test(expected=NumberFormatException.class)
public void testExt() {
helloWorld.ext();
} @After
public void tearDown() {
helloWorld = null;
}
}
二. ant整合junit測试
1. 生成測试报告:
<?xml version="1.0" encoding="UTF-8"? >
<project name="junit-test">
<property name="src" location="src" />
<property name="test" location="test" />
<property name="lib" location="lib" />
<property name="build" location="build" />
<property name="build.classes" location="${build}/classes" />
<property name="build.test" location="${build}/test" />
<property name="build.test.classes" location="${build.test}/classes" />
<property name="build.test.report" location="${build.test}/report" />
<!--
<property name="runTest" value="com.zdp.test.HelloWorldTest" />
-->
<property name="runTest" value="**/*Test.class"></property> <!-- 手动指明classpath, 一个path中能够加多个classpath,使用链式编写 -->
<path id="lib_path">
<fileset dir="${lib}" includes="*.jar" />
</path>
<path id="compile_path">
<path refid="lib_path" />
<pathelement location="${build.classes}"/>
</path>
<path id="compile_test_path">
<path refid="compile_path" />
<pathelement location="${build.test.classes}"/>
</path> <target name="clean">
<echo>1.開始清理文件</echo>
<delete dir="${build}"></delete>
</target> <target name="init">
<echo>2.项目的初始化</echo>
<mkdir dir="${build}"/>
<mkdir dir="${build.classes}"/>
<mkdir dir="${build.test}"/>
<mkdir dir="${build.test.classes}"/>
<mkdir dir="${build.test.report}"/>
</target> <target name="compile_src" depends="init">
<echo>3.编译源文件</echo>
<javac srcdir="${src}" destdir="${build.classes}"
classpathref="lib_path" includeantruntime="true"/>
</target> <target name="compile_test" depends="compile_src">
<echo>4.编译測试文件</echo>
<javac srcdir="${test}" destdir="${build.test.classes}"
classpathref="compile_path" includeantruntime="true"/>
</target> <target name="run_test" depends="clean, compile_test">
<echo>5.执行单元測试</echo>
<junit printsummary="false" haltonfailure="false">
<classpath refid="compile_test_path"></classpath>
<formatter type="xml"/>
<batchtest todir="${build.test.report}">
<fileset dir="${build.test.classes}" includes="${runTest}"/>
</batchtest>
</junit>
<junitreport todir="${build.test.report}">
<fileset dir="${build.test.report}" includes="TEST-*.xml"/>
<report format="frames" todir="${build.test.report}/html"/>
</junitreport>
</target>
<target name="end" depends="run_test">
<echo>6.測试结束</echo>
</target>
</project>
2. 生成doc文档并打包
<? xml version="1.0" encoding="UTF-8"? >
<project default="zip">
<property name="src" location="src"></property>
<property name="build" location="build"></property>
<property name="build.classes" location="${build}/classes"></property>
<property name="build.doc" location="${build}/doc/api"></property>
<property name="zip" location="${build}/zip"></property>
<property name="version" value="SNAPSHOT_0.1"></property>
<property name="projectName" value="helloworld_${version}"></property>
<property name="zipFileName" value="helloworld_${version}.zip"></property> <target name="clean">
<echo>1.開始清理文件</echo>
<delete dir="${build}"></delete>
</target> <target name="init">
<echo>2.项目的初始化</echo>
<mkdir dir="${build}"/>
<mkdir dir="${build.classes}"/>
<mkdir dir="${build.doc}"/>
</target> <target name="doc" depends="init">
<echo>3.生成doc文档</echo>
<javadoc sourcepath="${src}" private="true" windowtitle="HelloWorld JAVA DOC"
use="true" packagenames="com.zdp.*" destdir="${build.doc}"
charset="UTF-8" docencoding="UTF-8" encoding="UTF-8">
<classpath path="${build.classes}"></classpath>
</javadoc>
</target> <target name="zip" depends="doc">
<echo>4.生成zip包</echo>
<zip destfile="${zip}/${zipFileName}" duplicate="preserve">
<zipfileset dir="${build.doc}" includes="**/*.*" prefix="${projectName}/doc/api"></zipfileset>
<zipfileset dir="${src}" includes="**/*.*" prefix="${projectName}/src"></zipfileset>
</zip>
</target>
</project>
