用Yaml文件进行元素管理【转】

原文：http://www.cnblogs.com/milanmi/p/4636503.html

如界面有一个按钮，id号是test。如果进行对象化的话，就是test.click就可以了。不用每次都要去创建test对象。如果id号变了，我们也只需要改一下test的名称就行了。

使用Yaml需要用到下载jyaml的jar包。下载地址是http://www.java2s.com/Code/Jar/j/Downloadjyaml13jar.htm

TestBaidu.yaml

baidu_button:
  type:id
  value:su
baidu_input:
  type:id
  value:kw

解析yaml类 YamlUtil.java

package com.test.util;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.HashMap;
import java.util.Map;

import org.ho.yaml.Yaml;

public class YamlUtil {
    private String yamlfile;
    private WebDriver driver;
    private Map<String,Map<String,String>> ml;
    public YamlUtil(WebDriver driver,String yamlFilePath){
        this.yamlfile =yamlFilePath;
        this.driver=driver;
        getYamlFile();
    }
    public void getYamlFile(){
        File f = new File(this.yamlfile);

        try {
            ml= Yaml.loadType(new FileInputStream(f.getAbsolutePath()), HashMap.class);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    //创建by对象
    private By getBy(String key){
        By by = null;
        if (ml.containsKey(key)){
            Map<String,String> m = ml.get(key);
            String type = m.get("type");
            String value = m.get("value");
        switch(type){
            case "id":
                by = By.id(value);
                break;
            case "name":
                by = By.name(value);
                break;
            case "xpath":
                by = By.xpath(value);
                break;
            case "class":
                by = By.className(value);
                break;
            case "linkText":
                by = By.linkText(value);
                break;
            case "cssSelector":
                by= By.cssSelector(value);
                break;
            }
        }
        else
        {
            System.out.println("Locator "+key+" is not exist in  "+yamlfile);
        }
        return by;
    }
    //根据名称 返回webElement对象
    public WebElement getElement(String key){
        By by = this.getBy(key);
        WebElement  element = driver.findElement(by);
        return element;
    }
}
