單元測(cè)試工具 軟件測(cè)試
因此,如果想要使用不同的測(cè)試數(shù)據(jù)執(zhí)行一個(gè)測(cè)試用例多次,那么采用DataProvider;如果想要多次執(zhí)行一個(gè)測(cè)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(qǐng)看下面例子:
在測(cè)試類Test1中有2個(gè)用例,其中用例test2通過(guò)dataProvider提供參數(shù),而在DataProvider中提供了3組參數(shù),因此測(cè)試類Test1每次會(huì)執(zhí)行4個(gè)用例;
在工廠類FactoryWithDataprovider中,通過(guò)DataProvider為工廠方法提供參數(shù),因此工廠方法會(huì)創(chuàng)建2個(gè)Test1的實(shí)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(gè)實(shí)例,每個(gè)實(shí)例執(zhí)行4個(gè)用例,總共8個(gè)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")
