testng入门教程15数据驱动

testng在类 里面的数据驱动

package driver_test;


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

public class TestngDataProvider {
    
    /*@DataProvider(name="DP1")
    public Object[][] createData() {
        Object[][] createdata={
                { "001", "Jack", "London" }, { "002", "John", "New York" }, 
                { "003", "Mary", "Miami" },  { "004", "George", "california"}
        };
        return (createdata);
    }*/
    
    @DataProvider(name="DP1")
    public Object[][] createData(){
        return new Object[][] {
            { "001", "Jack", "London" }, { "002", "John", "New York" }, 
            { "003", "Mary", "Miami" },  { "004", "George", "california"}        
        };
    }
    
    @Test(dataProvider="DP1")
    public void testcase(String empid, String empName, String city){
        System.out.println("empid");
        System.out.println("empName");
        System.out.println("city");
    }
    
}

右键------->RunAs-------->testng           

运行结果如下：

empid
empName
city
empid
empName
city
empid
empName
city
empid
empName
city
PASSED: testcase("001", "Jack", "London")
PASSED: testcase("002", "John", "New York")
PASSED: testcase("003", "Mary", "Miami")
PASSED: testcase("004", "George", "california")

另外一种，在dataprovider里面写入方法

package driver_test;

import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;

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


public class driver_data {
    
    @DataProvider(name = "iterator")  
    public Iterator<Object[]> getData() {  
        Set<Object[]> set = new HashSet<Object[]>();  
        set.add(new String[] { "hello" });  
        Iterator<Object[]> iterator = set.iterator();  
        return iterator;  
    }  
  
    @Test(dataProvider = "iterator")  
    public void testIteraorData(String iterator) {  
        System.err.println("iterator  .. " + iterator);  
  
    }      
}

右键------->RunAs-------->testng           

运行结果如下：

iterator  .. hello
PASSED: testIteraorData("hello")
