Testng数据驱动之DataProvider的使用方式

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<Object[]>类型的数据。

Iterator<Object[]>类型

packagecom.testng.example.testngdemoone;importorg.testng.annotations.DataProvider;importorg.testng.annotations.Test;importjava.util.ArrayList;importjava.util.Iterator;importjava.util.List;publicclassTestngDemoOneApplicationTest{@DataProvider(name="dataProvider-testcase")publicIterator<Object[]>dataProvider(){List<Object> testCasePaths =newArrayList<Object>();
        testCasePaths.add("test1");
        testCasePaths.add("test2");
        testCasePaths.add("test3");
        testCasePaths.add("test4");List<Object[]> path =newArrayList<>();for(Object obj:testCasePaths){
            path.add(newObject[]{obj});}return path.iterator();}@Test(dataProvider ="dataProvider-testcase")publicvoidtestDataProviderIterator(String path){System.out.println(path);}}

测试执行结果

test1
test2
test3
test4
