本文将带你了解测试工具TestNG DataProvider的几种方法写法，希望本文对大家学测试工具有所帮助。
一、Method表示当前测试的方法
Dataprovidertest.java代码
package com.tzf.testng;
import java.lang.reflect.Method;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class DataProviderTest {
@DataProvider
public Object[][] providerMethod(Method method){
Object[][] result = null;
if(method.getName().equals("testmethod1")){
result = new Object[][]{new Object[]{1}};
}else if(method.getName().equals("testmethod2")){
result = new Object[][]{new Object[]{2}};
}else{
result = new Object[][]{new Object[]{3}};
}
return result;
}
@Test(dataProvider="providerMethod")
public void testmethod1(int param){
System.out.println("method1 received:"+param);
}
@Test(dataProvider="providerMethod")
public void testmethod2(int param){
System.out.println("method2 received:"+param);
}
@Test(dataProvider="providerMethod")
public void testmethod3(int param){
System.out.println("method3 received:"+param);
}
}
注意这里我的Dataprovider的name值没有指定，默认用的是方法名。 Testng.xml代码
运行结果代码
RemoteTestNG starting
method1 received:1
method2 received:2
method3 received:3
RemoteTestNG finishing: 145 ms
二、ITestContent当前测试的上下文信息
Dataprovidertest2.java代码
package com.tzf.testng;
import java.util.Random;
import org.testng.ITestContext;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class DataProviderTest2 {
@DataProvider
public Object[][] providerMethod(ITestContext context){
String[] groups = context.getIncludedGroups();
int size = 2;
for(String group : groups){
if(group.equals("function-test")){
size = 10 ;
break;
}
}
Object[][] result = new Object[size][];
Random r = new Random();
for(int i=0;i
result[i] = new Object[]{new Integer(r.nextInt())};
}
return result;
}
@Test(dataProvider="providerMethod",groups={"function-test","unit-test"})
public void testmethod1(Integer n){
System.out.println("method1 received:"+n);
}
}
Testng.xml代码
运行结果代码
RemoteTestNG starting
method1 received:-1987654923
method1 received:338477914
method1 received:1910366338
method1 received:107205369
method1 received:-1018164959
method1 received:-2060129321
method1 received:-803464435
method1 received:-814156781
method1 received:-1075504680
method1 received:-774924512
RemoteTestNG finishing: 151 ms
