（二）TestNg的工厂模式@Factory

目标：通过读取多个excel用例，自动创建Test

方法：根据官网提供的注解@Factory的用法，来创建多个测试类

工程结构：

1.首先在工程目录下创建一个caseexcel文件夹来存放用例

2.遍历文件夹获取用例文件

static public ArrayList<String> getCasePathList() {
        ArrayList<String> files = new ArrayList<String>();
        File file = new File("caseexcel/");
        File[] tempList = file.listFiles();
        if (tempList.length > 0) {
            for (int i = 0; i < tempList.length; i++) {
                if (tempList[i].isFile()) {
                    System.out.println("文     件：" + tempList[i]);
                    files.add(tempList[i].toString());
                }
                if (tempList[i].isDirectory()) {
                    // System.out.println("文件夹：" + tempList[i]);
                }
            }
        } else {
            throw new NullPointerException("没有找到case");
        }

        return files;
    }

3.测试类

将上一次测试类中的各个方法copy过来
新增属性publicCaseList、caseList用来接收测试用例

package com.testng.testng;

import java.util.List;

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

import Util.CaseModel;
import Util.CaseType;
import Util.Driver;
import Util.StepModel;
import Util.WebElementZ;

public class WebTest {
    private List<CaseModel> publicCaseList;//公共用例
    private List<CaseModel> caseList;//普通用例
       //构成方法；
      @SuppressWarnings("static-access")
    public WebTest(List<CaseModel> publicCaseList,List<CaseModel> caseList) {
          this.publicCaseList = publicCaseList;
          this.caseList = caseList; 
      }
     
         @Test(dataProvider = "dp")
        public void f(CaseModel caseModel) {
             System.out.println("执行了用例" + caseModel);
             doCase(caseModel);
        }

        @AfterClass
        public void AfterClass() {
             Driver.getChromeDriver().quit();
             Driver.setChromeDriver(null);
        }

        @BeforeClass
        public void BeforeClass() {
        }
        
        @DataProvider
        public Object[] dp() {
            //获取用例
            int size = caseList.size();
            Object[] objects = new Object[size];
            for (int i = 0; i < objects.length; i++) {
                objects[i] = caseList.get(i);
            }
            return objects;
        }
        
        //根据casel模型执行用例
        public void doCase(CaseModel caseModel) {
            for (int i = 0; i < caseModel.getStepModels().size(); i++) {
                StepModel stepModel = caseModel.getStepModels().get(i);
                System.out.println(stepModel);
                String object = stepModel.getObject();
                if (stepModel.getPrecondition() != null) {
                    //执行前置条件
                    for (CaseModel caseModel2 : publicCaseList) {
                        if (stepModel.getPrecondition().equals(caseModel2.getCaseName())) {
                            //根据casename查找到说要执行的公共用例
                            doCase(caseModel2);
                            break;
                        }
                    }
                }
                if (object.equals("driver")) {
                    Driver.action(stepModel);
                } else {
                    //懒得写elseif。这里假装判断了是element
                    WebElementZ.ElementAction(stepModel);
                }
            }
        }
}

4.根据用例个数生成多个测试类对象

    @Factory
    public Object[] createInstances() {
        List<String> pathList = getCasePathList();//获取测试用例文件
        Object[] result = new Object[pathList.size()];
        for (int i = 0; i < pathList.size(); i++) {
              //生成测试类对象，将公共用例与普通用例解析后传入对象
            CaseModel.getCaseList(pathList.get(i), CaseType.publicCase);
            result[i] = new WebTest(CaseModel.getCaseList(pathList.get(i), CaseType.publicCase),
                    CaseModel.getCaseList(pathList.get(i), CaseType.ordinaryCase));
        }
        return result;
    }

5.在testng.xml中添加class

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
  <test thread-count="5" name="Test">
    <classes>
      <class name="com.testng.testng.WebTestFactory"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

完事

6.以下官网内容

5.8 - 工厂

工厂创建了10个测试类@Factory

public class WebTestFactory {
  @Factory
  public Object[] createInstances() {
   Object[] result = new Object[10]; 
   for (int i = 0; i < 10; i++) {
      result[i] = new WebTest(i * 10);
    }
    return result;
  }
}

测试类

public class WebTest {
  private int m_numberOfTimes;
  public WebTest(int numberOfTimes) {
    m_numberOfTimes = numberOfTimes;
  }
 
  @Test
  public void testServer() {
   for (int i = 0; i < m_numberOfTimes; i++) {
     // access the web page
    }
  }
}

通过testng.xml调用，添加工厂WebTestFactory

<class name="WebTestFactory" />

通过代码执行

TestNG testNG = new TestNG();
testNG.setTestClasses(WebTestFactory.class);
testNG.run();
