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
```
<dependency>
    <groupId>com.github.phoenix-young</groupId>
    <artifactId>testng-ex</artifactId>
    <version>0.4.7</version>
</dependency>
```
1. IDE配置(以配置IDEA为例)
  Run->Edit Configurations->Defaults->TestNg->Listeners下添加 com.apitest.nglisteners.ApiTestListener

常用

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){
    
    }
}

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){

}

Method数据源

同类名下

public class InnerFunctionTest {

    @Test
    public void innerFuntion(@Func(name = "getValues") String value){

    }

    public List<String> getValues(){
        return Arrays.asList("A","B","C");
    }

}

静态方法

public class StaticFunctionProvider{

    public static List<Integer> 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<Console> 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<Integer> getData(String p1,String p2){
        int value = Integer.parseInt(p1);
        List<Integer> list = new ArrayList<>();
        for(int i =0;i<value;i++){
            list.add(i);
        }
        return list;
    }
}

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

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

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

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<String,String> 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){
        
    }

}
