接口测试进阶3-1数据驱动测试

数据驱动

相同的测试脚本使用不用的测试数据执行，并完全分离了测试数据和测试行为。这样的模式成为数据驱动

testNG实现数据驱动的两个关键注解

@DataProvider
@Parameters

在当前类中指定数据源

#java
package DateDriver812;

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

public class Lesson1Data {
    @DataProvider(name = "provider")
    public Object[][] createData(){
        /**
         * 提供数据源
         */
        return new Object[][]{
                {"阿里","马云"},
                {"腾讯","马化腾"}
        };
    }
    @Test(dataProvider="provider")
    public void testDataProvider(String company,String people){
        /**
         * 接收数据源，每一行作为一组数据，每次接收一组执行一次测试
         */
        System.out.println("company:"+company+"\t"+"people:"+people);
    }
}

company:阿里 people:马云
company:腾讯 people:马化腾

数据源在其他类中

#java
package DateDriver812;

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

public class Lesson1Data {

    @Test(dataProviderClass = testdata.TestData.class,dataProvider = "test1")
    /**
     * 指定类：packageName.className.class（class不能少）
     * 指定dataProvider
     */
    public void testDataProviderClass(String company,String people){
        System.out.println("company:"+company+"\t"+"people:"+people);
    }
}
//数据源
package testdata;

import org.testng.annotations.DataProvider;

public class TestData {
    @DataProvider(name = "test1")
    public static Object[][] createDdata(){
        return new Object[][]{
                {"网易","丁磊"},
                {"京东","刘强东"}
        };
    }
}

company:网易 people:丁磊
company:京东 people:刘强东
