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 。
6. junit怎么写 下面是我做项目时的例子 , 希望对你有所帮助 。
