12_java + selenium + testng implements simple UI automation

Create a new Maven project and add required dependencies

1. Create a new Maven project
2. Add the required dependencies in pom.xml. Here we only need selenium and testng.

<!-- https://mvnrepository.com -->
<dependencies>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.4.0</version>
    </dependency>

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.8.8</version>
        <scope>test</scope>
    </dependency>

</dependencies>

You can search for the required library in https://mvnrepository.com, select the version, and copy its dependency information

Configure the browser and get a handle

1. Create a new Brower.java, configure browser settings, and create a FirefoxDriver instance

package com.test.testng;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;

/**

public class Brower {
    
    
    WebDriver driver;

    public WebDriver firefox(){
    
    
        String webDriverPath = "/Users/dengchunmei/WebDriver/geckodriver29";
        String firefoxPath = "/Applications/Firefox.app/Contents/MacOS/firefox";
        //关掉火狐浏览器的日志
        System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"/dev/null");
        System.setProperty("webdriver.gecko.driver",webDriverPath);
        System.setProperty("webdriver.firefox.bin",firefoxPath);

        FirefoxOptions options = new FirefoxOptions();
        options.addArguments("--start-maximized"); // 启动时自动最大化窗口
        options.addArguments("--disable-popup-blocking"); // 禁用阻止弹出窗口
        options.addArguments("no-sandbox"); // 启动无沙盒模式运行
        options.addArguments("disable-extensions"); // 禁用扩展
        options.addArguments("no-default-browser-check"); // 默认浏览器检查
        Map<String, Object> prefs = new HashMap();
        prefs.put("credentials_enable_service", false);
        prefs.put("profile.password_manager_enabled", false);
        //options.setExperimentalOption("prefs", prefs);// 禁用保存密码提示框

        driver = new FirefoxDriver(options);
        //设置寻找一个元素的时间
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

        return driver;
    }
}

Open the URL, locate the page element and operate

1. Create a new TestDemo.java, mark the initialization method with the @BeforeTest annotation, end the processing with the @AfterTest mark, and the test object method with the @Test mark. Use @Parameters ("searchWord") to specify that the passed parameter values ​​come from the configuration in TestNG.xml

package com.test.testng;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

/**
* @Author chunmei deng
* @Description 测试Demo
* @Date 2021/3/21
*/
public class TestDemo {
    
    
    WebDriver driver;

    @BeforeTest
    public void init() {
    
    
        String url = "http://www.baidu.com";

        //新建一个浏览器句柄
        driver = new Brower().firefox();
        //driver = (WebDriver) new FirefoxDriver();
        //打开URL
        driver.get(url);
    }

    @Test
    @Parameters("searchWord")
    public void search(String searchWord) throws InterruptedException {
    
    
        //输入搜索字符串
        driver.findElement(By.xpath("//*[@id=\"kw\"]")).sendKeys(searchWord);
        //点击[百度一下]按钮
        driver.findElement(By.xpath("//*[@id=\"su\"]")).click();
        Thread.sleep(2000);
    }

    @AfterTest
    public void teardown() {
    
    
        driver.quit();
    }

}

Create a new TestNG.xml and configure the test

1. The content is as follows

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Test Of TestNG">

    <test verbose="2" name="百度搜索">
        <parameter name="searchWord" value=“淘宝" />

        <classes>
            <class name="com.test.testng.TestDemo">
                <methods>
                    <include name="search" />
                </methods>
            </class>
        </classes>
    </test>

</suite>

Run program

1. Run TestNG.xml

2. The running effect is as follows

to generate a test report

1. In the running configuration, check Use default reporters, and the running results will automatically generate a report.
