因此，如果想要使用不同的測試數據執行一個測試用例多次，那么采用DataProvider；如果想要多次執行一個測試類的所有用例，那么采用Factory。
當然，Factory與DataProvider也可結合在一起使用，請看下面例子：
在測試類Test1中有2個用例，其中用例test2通過dataProvider提供參數，而在DataProvider中提供了3組參數，因此測試類Test1每次會執行4個用例；
在工廠類FactoryWithDataprovider中，通過DataProvider為工廠方法提供參數，因此工廠方法會創建2個Test1的實例。
1 public class Test1 {
2 private String name;
3 public Test1(String name) {
4 this.name = name;
5 }
6
7 @Test
8 public void test1() {
9 System.out.println("test1: His name is " + name);
10 }
11
12 @Test(dataProvider = "data1")
13 public void test2(String hobby) {
14 System.out.println("test2: " + name + " likes " + hobby);
15 }
16
17 @DataProvider(name = "data1")
18 public Object[][] createdata() {
19 return new Object[][] {
20 {"baozoumanhua"}，
21 {"movie"}，
22 {"music"}
23 };
24 }
25 }
26
27 public class FactoryWithDataprovider {
28
29 @DataProvider(name = "data2")
30 public Object[][] createdata() {
31 return new Object[][] {
32 {"wangnima"}，
33 {"wangnimei"}，
34 };
35 }
36
37 @Factory(dataProvider = "data2")
38 public Object[] createInstace(String name) {
39 return new Object[] {
40 new Test1(name)
41 };
42 }
43 }
執行結果如下：2個實例，每個實例執行4個用例，總共8個用例。
test1: His name is wangnima
test1: His name is wangnimei
test2: wangnima likes baozoumanhua
test2: wangnima likes movie
test2: wangnima likes music
test2: wangnimei likes baozoumanhua
test2: wangnimei likes movie
test2: wangnimei likes music
PASSED: test1
PASSED: test1
PASSED: test2("baozoumanhua")
PASSED: test2("movie")
PASSED: test2("music")
PASSED: test2("baozoumanhua")
PASSED: test2("movie")
PASSED: test2("music")
