DataProvider
@DataProvider 注解帮助我们编写数据驱动的测试用例。@DataProvider 注解使我们能够通过传递不同的数据集多次运行测试方法。
以下是@DataProvider 注解支持的属性列表：
属性描述name此数据提供者的名称。如果未提供，则此数据提供程序的名称将自动设置为方法的名称。带注解的方法必须返回一个 Object[][]，其中每个 Object[] 都可以分配测试方法的参数列表。parallel如果设置为true，则使用此数据提供程序生成的测试将并行运行。默认值为false。dataProvider作为数据提供者只能返回Object[][]和Iterator
Iterator
package com.testng.example.testngdemoone;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class TestngDemoOneApplicationTest {
@DataProvider(name="dataProvider-testcase")
public Iterator
List
testCasePaths.add("test1");
testCasePaths.add("test2");
testCasePaths.add("test3");
testCasePaths.add("test4");
List
for(Object obj:testCasePaths){
path.add(new Object[]{obj});
}
return path.iterator();
}
@Test(dataProvider = "dataProvider-testcase")
public void testDataProviderIterator(String path) {
System.out.println(path);
}
}
