基于Selenium和Firefox的自动化测试

一、安装Selenium
在Eclipse中导入geckodriver，然后内置插件中安装即可。
二、安装Firefox和Selenium IDE插件
先安装Firefox，然后搜索Firefox add-on，从插件中搜索Selenium即可。
三、录制导出代码
打开Selenium，开始录制，对任意学号完成一次操作。然后将录制完成的视频导出为Java(WebDriver+Junit)格式。

注：这里可以用katalon替代。


四、完成自动化测试
可利用Junit的自动化测试对单一操作代码进行改写，使之实现自动化测试。在导入数据的时候有两个需要处理的细节：由于原数据第一行为表头，因此在读取数据的时候需要额外进行一次readLine()；由于最后可能会有空行，而split函数在执行时不会对csv的空值进行操作，因此会产生数组越界错误。最简便的解决方法是手动删除空行。关键代码如下：
TestLab2.java:

package testWeb;

import java.util.regex.Pattern;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;

  private StringBuffer verificationErrors = new StringBuffer();
  
  public TestLab2(String id,String password,String github) {
	  this.id = id;
	  this.password=password;
	  this.github=github;
  }
  
  @Parameters 
  public static Collection<String[]>getData() throws IOException{
	  Collection<String[]> list = new ArrayList<>();
	  BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\dell\\Desktop\\ST\\info.csv"));
	  br.readLine();//将表头去除
		String temp = br.readLine();
		temp = br.readLine();
		
		while(temp != null) {

		  String [] split = new String[3];
		  String[] result = temp.split(",");
			  
			  split[0] = result[1];
			  split[1] = result[1].substring(4);
			  split[2] = result.length == 4 ? result[3] : "";
			  list.add(split);
				temp = br.readLine();
			  
		  }
		  
		  
		return list;
	  
  }

  @Before
  public void setUp() throws Exception {

	  driver.findElement(By.name("id")).sendKeys(id);
      driver.findElement(By.name("password")).click();
      driver.findElement(By.name("password")).clear();
    driver.findElement(By.name("password")).sendKeys(password);
