3/3 实验报告

实验三：Software Unit Testing

实验目的和要求

对 Java 单元测试有初步的了解，学会使用 Junit 编写自己的测试用例，掌握对被测试类进行测试的实现方法；了解轻量级的自动化工具 Selenium，学会使用 Selenium 进行网站自动化测试（选做）。

实验环境

Eclipse、jdk1.8、chrome browser

实验步骤

利用 Junit 编写测试用例，并对被测试类进行相关功能测试。
a) 验证 Book 类的 equals 方法；

Book.java：


package cn.edu.njupt;
public class Book {
    private String title;
    private double price;
    public Book(String title, double price) {
        this.title = title;
        this.price = price;
    }
    public boolean equals(Object object) {
        if(object instanceof Book){
            Book book=(Book)object;
            return getTitle().equals(book.getTitle())
                    && getPrice()==book.getPrice();
        }
        return false;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public double getPrice() {
        return price;
    }
    public void setPrice(double price) {
        this.price = price;
    }
}

BookTest.java：


package cn.edu.njupt;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;
class BookTest {
    private Book book1;
    private Book book2;
    @BeforeEach
    void setUp() {
        book1=new Book("ES",12.99);
        book2=new Book("The Grate",11.99);
    }
    @AfterEach
    void tearDown() {
        book1=null;
        book2=null;
    }
    @Test
    void testEquals() {
        assertFalse((book2.equals(book1)));
        assertTrue((book1.equals(book1)));
    }
}

B）设计 Triangle 类的测试用例，并进行测试。

Triangle.java：


package cn.edu.njupt;
public class Triangle {
    protected long lborderA=0;
    protected long lborderB=0;
    protected long lborderC=0;
    public Triangle(long lborderA, long lborderB, long lborderC) {
        this.lborderA = lborderA;
        this.lborderB = lborderB;
        this.lborderC = lborderC;
    }
    public static boolean isTriangle(Triangle triangle){
        boolean isTriangle=false;
        if((triangle.lborderA>0 && triangle.lborderA<=Long.MAX_VALUE/2)
                &&(triangle.lborderB>0 && triangle.lborderB<=Long.MAX_VALUE/2)
                &&(triangle.lborderC>0 && triangle.lborderC<=Long.MAX_VALUE/2))
            if((triangle.lborderA < (triangle.lborderB+triangle.lborderC))
                    &&(triangle.lborderB < (triangle.lborderA+triangle.lborderC))
                    &&(triangle.lborderC < (triangle.lborderB+triangle.lborderA)))
                    isTriangle=true;
        return isTriangle;
    }

    public static String getType(Triangle triangle){
        String strType="不是三角形";
        if(isTriangle(triangle)){
            if(triangle.lborderA==triangle.lborderB
                && triangle.lborderB==triangle.lborderC){
                strType="等边三角形";
            }
            else if((triangle.lborderA !=triangle.lborderB)
                &&(triangle.lborderB !=triangle.lborderC)
                &&(triangle.lborderA !=triangle.lborderC))
                strType="不等边三角形";
            else{
                strType="等腰三角形";
            }
        }
        return strType;
    }
}

TriangleTest.java：


package cn.edu.njupt;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;
class TriangleTest {
    private Triangle triangle1;
    private Triangle triangle2;
    private Triangle triangle3;
    private Triangle triangle4;
    private Triangle triangle5;
    private Triangle triangle6;
    @BeforeEach
    void setUp() {
        triangle1=new Triangle(3,3,3);
        triangle2=new Triangle(3,4,5);
        triangle3=new Triangle(3,3,5);
        triangle4=new Triangle(-1,3,5);
        triangle5=new Triangle(3,10,5);
        triangle6=new Triangle(3,3,5);
    }
    @AfterEach
    void tearDown() {
        triangle1=null;
        triangle2=null;
        triangle3=null;
        triangle4=null;
        triangle5=null;
        triangle6=null;
    }
    @Test
    void isTriangle() {
        assertTrue(Triangle.isTriangle(triangle6));
        assertFalse(Triangle.isTriangle(triangle4));
        assertFalse(Triangle.isTriangle(triangle5));
    }
    @Test
    void getType() {
        assertEquals("等边三角形",Triangle .getType(triangle1));
        assertEquals("不等边三角形",Triangle.getType(triangle2));
        assertEquals("等腰三角形",Triangle.getType(triangle3));
        assertEquals("不是三角形",Triangle.getType(triangle4));
    }
}

4、利用 Selenium 进行 Web 应用程序的自动化测试。（选做）
A）导入Selenium的jar包

B）下载对应Chrome浏览器版本的驱动

（要修改Demo.java中对应的路径）
C）编写demo类：

package king.test;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.List;
import java.util.concurrent.TimeUnit;
public class Demo1 {
    private WebDriver driver;

    @Before
    public void setUp(){
        //设置谷歌浏览器的驱动
        System.setProperty("webdriver.chrome.driver","C:\\Program Files (x86)\\Google\\Chrome\\Application\\chromedriver.exe");
        //启动谷歌浏览器
        driver=new ChromeDriver();
        //设置默认超时时间
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }
    @After
    public void tearDown() throws Exception{
        //关闭浏览器
        driver.quit();
    }
    @Test
    public void test222() throws Exception{
        //打开测试页面
        driver.get("file:///E:/test.html");
        //通过id找到第一个输入框
        WebElement un =driver.findElement(By.id("un"));
        //第一个输入框输入aaa
        un.sendKeys("aaa");
        //通过id找到第二个输入框
        WebElement pw =driver.findElement(By.className("lala"));
        //第一个输入框输入bbb
        pw.sendKeys("bbb");
        //通过id找到第三个输入框
        WebElement co =driver.findElement(By.name("code"));
        //第一个输入框输入ccc
        co.sendKeys("ccc");
        Thread.sleep(2000);
        //找到页面中的所有的input标签
        List<WebElement> inputs=driver.findElements(By.tagName("input"));
        //获取第四个input标签
        WebElement btn = inputs.get(3);
        //点击按钮
        btn.click();
        Thread.sleep(3000);
    }
}

编写演示页面：test.html（要修改Demo.java中对应的路径）

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="Generator" content="EditPlus®">
    <meta name="Author" content="">
    <meta name="Keywords" content="">
    <meta name="Description" content="">
    <title>Document</title>
</head>
<body>
    <input id="un" class="css1" name="username">
    <input id="pw" class="css2 lala" name="password">
    <input id="co" class="css3" name="code"><br>
    <input type="button" id="btn" class="css4" name="submit" value="按钮">
    <script>
        document.getElementById('btn').onclick=function(){
            alert("haha");
        }
    </script>
</body>
</html>
