2. java junit单元测试怎么写
package com.yuanqi.zfb.test;
import org.junit.Test;
import com.yuanqi.zfb.util.VerifyCodeUtils;
public class Atest {
@Test
public void test(){
String verifycode =VerifyCodeUtils.generateVerifyCode(8);
System.out.println(verifycode);
}
@Test
public void test2(){
// String str="2015-11-23 11:23:44";
/* boolean b= str.matches("\\d{4}-\\d{2}-\\d{2} \\d{2}:\\d{2}:\\d{2}");
if(b){
System.out.println("ok");
}else{
System.out.println("222222");
}*/
String str="2015112311:23:44";
boolean b= str.matches("\\d{10}:\\d{2}:\\d{2}");
System.out.println(b);
}
@Test
public void test3(){
String trTime="2014112800:05:48";
String inyear=trTime.substring(0, 4);
String inmonth=trTime.substring(4,6);
String inday=trTime.substring(6,8);
String intime=trTime.substring(8);
String time=inyear+"-"+inmonth+"-"+inday+" "+intime;
System.out.println(time);
}
}
3. Java Junit Test 要怎么写
一般不用写，直接测试方法，在测试的方法上加上注解@Test
import org.junit.Test;
public class TestJunit {
@Test
public void TestSaveMethod(){
Food food=new Food（"红烧肉"， new BigDecimal(45.5).setScale(2, BigDecimal.ROUND_HALF_UP), "hsr.jpg");
SaveFood(food);
}
public void SaveFood(Food food){
if(food!=null){
food.setId(UUID.randomUUID().toString());
System.out.println("Food Save is OK!");
System.out.println（"当前ID:"+food.getId（)+" 名称："+food.getName（)+" 单价："+food.getPrice());
}else{
System.out.println("Food Save is False!");
}
}
}
class Food implements Serializable{
private String id;
private String name;
private BigDecimal price;
private String icon;
public Food(String name,BigDecimal price,String icon) {
this.name=name;
this.price=price;
this.icon=icon;
}
public void setId(String id) {
this.id = id;
}
public String getId() {
return id;
}
public String getName() {
return name;
}
public BigDecimal getPrice() {
return price;
}
public String getIcon() {
return icon;
}
}
//这样的话RUN 的时候就会出现JUnit测试
4. java中如何使用junit呢,求具体步骤
比方说，你在A类里面写了一个方法：
pulic void addNumber(int a) {
System.out.println(a+1);
}
这时候，你要测试你写的方法对不对，就应用到Junit。通常来说，测试类单独写在一个类文件里面。你可以再创建一个test.java，在这个类里面你要测试刚才的方法，你需要再写一个方法：
在test.java中：
public class test {
@Test （注意这里要导入Junit包，按ctrl + 1,Java中，任何报错，你先按ctrl+1，它都会有提示解决方法。这个1是指Q上面的那个1）
public void testAddNumber() {
A a = new A();
a.addStudent(1);
}
}
最后，双击你书写的这个方法，就是点testAddNumber点两下，然后右键，run as Junit Test
5. java和junit写类与测试类
/** Book类 */
public class Book {
public String name;
public String author;
private int availNum;
public Book() {
this("", "", 0);
}
public Book(String name, String author, int availNum) {
this.name = name;
this.author = author;
this.availNum = availNum;
}
public int getAvailNum() {
return availNum;
}
public void setAvailNum(int availNum) {
this.availNum = availNum;
}
public boolean subscribe() {
if (availNum > 0) {
availNum--;
return true;
}
return false;
}
public boolean cancelSubscribe() {
availNum++;
return true;
}
}
/** Book类的单元测试类 */
import junit.framework.TestCase;
public class TestBook extends TestCase {
public void testBook() {
Book book = new Book("Thinking in Java", "Bruce Eckel", 3);
assertEquals(true, book.subscribe（)）；// 第一次预借，应该是成功的
assertEquals(2, book.getAvailNum（)）；// 此时的可预借数是2
assertEquals(true, book.cancelSubscribe（)）；// 取消预借，应该是成功的
assertEquals(3, book.getAvailNum（)）；// 此时的可预借数是3
book.setAvailNum(0)；// 将可预借数设为0
assertEquals(false, book.subscribe（)）；// 此时预借，应该是不成功的
}
public static void main(String[] args) {
junit.textui.TestRunner.run(Book.class);
}
}
上面的测试类可以不要main函数，直接在集成开发环境里用JUnit执行单元测试。
