testng入门教程13同文件数据驱动

下面是@DataProvider有name和没有name时

有name的时候可以引用name 即：@DataProvider(name="testData")---------->@Test(dataProvider="testData")

package data_driver;

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

public class TestDataDriven {
    @DataProvider(name="testData")
    public Object[][] dataProvider(){
        return new Object[][]{{1,2},{2,3},{3,4}};
    }

    @Test(dataProvider="testData")
    public void testDataDriven(int a,int b){
        System.out.println("this is :"+(a+b));
    }
}

右键----->RunAs----->TestNG test   运行结果如下：

没有name的时候可以引用方法名即：

package data_driver;

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class TestDataDriven{
    @DataProvider
    public Object[][] dataprovider(){
        return new Object[][]{{1,2},{2,3},{3,4},{4,5},{5,6}};

    }

    @Test(dataProvider="dataprovider")
    public void testDataDriven(int a, int b){
        System.out.println("this is :"+ (a + b));
    }
}
