因此，如果想要使用不同的測試數(shù)據(jù)執(zhí)行一個測試用例多次，那么采用DataProvider；如果想要多次執(zhí)行一個測試類的所有用例，那么采用Factory。
　　當(dāng)然，F(xiàn)actory與DataProvider也可結(jié)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(shù)，而在DataProvider中提供了3組參數(shù)，因此測試類Test1每次會執(zhí)行4個用例；
　　在工廠類FactoryWithDataprovider中，通過DataProvider為工廠方法提供參數(shù)，因此工廠方法會創(chuàng)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(zhí)行結(jié)果如下：2個實例，每個實例執(zhí)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")
