JUnit+ANT自动测试实验

目标：
1. 使用ANT自动化测试。
2. 自动化测试报告。
3. 定时执行自动化测试。（未实现。）

被测试类 DefaultCalculator.java：


package com.don.classes;






/** *//**


* @author Administrator


*


*/




public class DefaultCalculator ...{


private int x, y;




/** *//**


*


*/




public DefaultCalculator(int x, int y) ...{


this.x = x; this.y = y;


}






public int Add() ...{


return x + y;


}






public int Subtract() ...{


return x - y;


}






public int Multiply()...{


return x * y;


}






public int Divide() ...{


return x / y;


}






public int getX() ...{


return x;


}






public int getY() ...{


return y;


}




}



测试用例DefaultCalculatorTest.java:


package com.don.classes;




import static org.junit.Assert.*;


import org.junit.After;


import org.junit.Before;


import org.junit.Test;




import com.don.classes.DefaultCalculator;


import java.util.ArrayList;


import java.util.List;






public class DefaultCalculatorTest ...{


private List<DefaultCalculator> calcs = new ArrayList<DefaultCalculator>();




@Before




public void setUp() throws Exception ...{


calcs.add(new DefaultCalculator(20, 40));


calcs.add(new DefaultCalculator(-10, -10));


calcs.add(new DefaultCalculator(40, -10));


}




@After




public void tearDown() throws Exception ...{


calcs = null;


}




@Test




public void testDefaultCalculator() ...{


assertEquals(10, calcs.get(0).getX());


assertEquals(40, calcs.get(0).getY());


assertEquals(-10, calcs.get(1).getX());


assertEquals(-10, calcs.get(1).getY());


assertEquals(40, calcs.get(2).getX());


assertEquals(-10, calcs.get(2).getY());


}




@Test




public void testAdd() ...{


assertEquals(50, calcs.get(0).Add());


assertEquals(-20, calcs.get(1).Add());


assertEquals(30, calcs.get(2).Add());


}




@Test




public void testSubtract() ...{


assertEquals(-30, calcs.get(0).Subtract());


assertEquals(0, calcs.get(1).Subtract());


assertEquals(50, calcs.get(2).Subtract());


}




@Test




public void testMultiply() ...{


assertEquals(400, calcs.get(0).Multiply());


assertEquals(100, calcs.get(1).Multiply());


assertEquals(-400, calcs.get(2).Multiply());


}




@Test




public void testDivide() ...{


assertEquals(0, calcs.get(0).Divide());


assertEquals(1, calcs.get(1).Divide());


assertEquals(-4, calcs.get(2).Divide());


}




}
