TestNg 数据源

TestNg-Ex

• 简介
  TestNg-Ex主要是针对原testng做了一层扩展，目前支持的数据源有Value,Func,Csv,Enum,Spring,Json。
  后续其他数据源例如DB会增加

• 依赖
  JDK1.8

• 配置

  1. MAVEN依赖

  
      com.github.phoenix-young
      testng-ex
      0.4.7
  
  

  2. IDE配置(以配置IDEA为例)
     Run->Edit Configurations->Defaults->TestNg->Listeners下添加 com.apitest.nglisteners.ApiTestListener

• 常用

  1. Values数据源

  package com.apitest.sample;
  import com.apitest.dataProvider.Value;
  import org.testng.annotations.Test;
  
  public class ValueProviderTest {
  
      @Test
      public void intValue(@Value(ints = {1,2,3}) int value){
  
      }
  
      @Test void stringValue(@Value(strings = {"T1","T2","T3"})String value){
      
      }
  }
  
  

  2. Enum数据源(不需要任何注解)

  public enum Company {
      Microsoft,
      Sony,
      Nintendo;
  }
  
  public enum Console {
      XBOXONE(Company.Microsoft,2000),
      XBOX360(Company.Microsoft,1500),
      SWITCH(Company.Nintendo,2300),
      PS4(Company.Sony,1700),
      PS3(Company.Sony,1300),
      WII(Company.Nintendo,800),
      WIIU(Company.Nintendo,1300);
  
      private Company company;
      private int price;
  
      Console(Company company,int price){
          this.company = company;
          this.price = price;
      }
  
      public Company getCompany() {
          return company;
      }
  
      public int getPrice() {
          return price;
      }
  }
  
  @Test
  public void enumInjectTest(Console console){
  
  }
  

  3. Method数据源

     • 同类名下

     public class InnerFunctionTest {
     
         @Test
         public void innerFuntion(@Func(name = "getValues") String value){
     
         }
     
         public List getValues(){
             return Arrays.asList("A","B","C");
         }
     
     }
     

     • 静态方法

     public class StaticFunctionProvider{
     
         public static List getValues(){
             return Arrays.asList(1,2,3);
         }
     
     }
     

     public class StaticFunctionTest {
     
         @Test
         public void staticFunction(@Func(name = "getValues",provider = StaticFunctionProvider.class) int value){
     
         }
     }
     

     • 外部实例方法（需要有无惨构造函数)

     public class OuterFunctionProvider {
         public List getConsoles(){
             return Arrays.asList(Console.values()).stream().filter(c->c.getCompany() == Company.Microsoft).collect(Collectors.toList());
         }
     }
     

     public class OuterFunctionTest {
         @Test
         public void outerFunction(@Func(name = "getConsoles",provider = OuterFunctionProvider.class) Console console){
     
         }
     }
     

     • 带参数的方法(方法参数只能是string类型)

     public class FunctionWithParameterTest {
     
         @Test
         public void functionWithParameter(@Func(name = "getData",args = {"5","2"})int value){
     
         }
     
         public List getData(String p1,String p2){
             int value = Integer.parseInt(p1);
             List list = new ArrayList<>();
             for(int i =0;i

  4. CSV数据源

     • id	name	age
       1	test1	22
       2	test2	18
       3	test3	19

       csv数据 (CSV文件需要和测试类放在同一PACKAGE下)

       id	name	age
       1	test1	22
       2	test2	18
       3	test3	19

     • CSV转化成POJO

     public class Student implements Serializable {
     
         private int id;
     
         private String name;
     
         private int age;
     
         public int getId() {
             return id;
         }
     
         public void setId(int id) {
             this.id = id;
         }
     
         public String getName() {
             return name;
         }
     
         public void setName(String name) {
             this.name = name;
         }
     
         public int getAge() {
             return age;
         }
     
         public void setAge(int age) {
             this.age = age;
         }
     }
     

     public class csvDataProvider {
     
         /**
          * Csv不指定File默认为当前类名同名CSV文件
          * 此例为csvDataProvider.csv
          * @param student
          */
         @Test
         public void csvData(@Csv Student student){
         
         }
     
         /**
          * 指定csv文件名
          */
         @Test
         public void csvDataWithFileName(@Csv(files = "csvDataProvider.csv") Student student){
         
         }
     
         /**
          * 用MAP类型代替POJO
          */
         @Test
         public void csvDataUsingMap(@Csv Map student){
         
         }
     }
     

• 组合（每个参数可以理解为一个维度，多个参数组合就生成笛卡尔积,针对POJO对象需要实现 Serializable 接口)

public class CombinationProviderTest {

    /**
     * console有7个枚举值，company有3个枚举值
     * 最终会生成7*3=21组测试数据
     */
    @Test
    public void enumCombinationTest(Console console, Company company){

    }

    /**
     * console有7个枚举值，value有3组数字，str有两组字符串
     * 最终会生成 7*3*2=42组测试数据
     */
    @Test
    public void otherCombinationTest(Console console, @Value(ints = {1,2,3}) int value,@Value(strings = {"a","b"}) String str){
        
    }

}

• 过滤（过滤掉不需要的组合)

package com.apitest.sample.combination;

import com.apitest.annotations.Filter;
import com.apitest.testModels.Company;
import com.apitest.testModels.Console;
import org.testng.annotations.Test;

public class CombinationWithFilterTest {


    /**
     * console有7个枚举值，company有3个枚举值
     * 过滤器只需要company == Company.Microsoft
     * 最终生成7*1=7组测试数组
     */
    @Test
    @Filter(method = "filterCompany")
    public void filterTest(Console console, Company company){

    }

    /**
     * 注意事项
     * 1. 过滤方法的参数类型和个数必须与测试方法一致
     * 2. 过滤方法的返回类型一律为布尔类型
     */
    public boolean filterCompany(Console console,Company company){
        return company == Company.Microsoft;
    }


    public boolean filterCompany2(Console console,Company company){
        return console == Console.PS4 || console == Console.SWITCH;
    }


    /**
     * 由于有两组过滤器
     * 最终生成console == Console.PS4 || console == Console.SWITCH 并且 company == Company.Microsoft 两组测试数据
     */
    @Test
    @Filter(method = "filterCompany")
    @Filter(method = "filterCompany2")
    public void filterTest2(Console console,Company company){
        
    }

}
