運行testng.xml，結(jié)果如下：
　　name:dadaorufeng，age:29
　　name:zhangsan，age:28
　　剛才這段代碼，定義數(shù)據(jù)源和使用數(shù)據(jù)源的代碼在同一個class中，如果不在同一個class的話，怎么辦呢？parameterizedTest2.java中定義數(shù)據(jù)源，
parameterizedTest3.java使用數(shù)據(jù)源
parameterizedTest2.java
import org.testng.annotations.DataProvider;
public class parameterizedTest2 {
// 定義數(shù)據(jù)源
@DataProvider(name = "test")
public static Object[][] createData() {
return new Object[][]{{"dadaorufeng"，29}，{"zhangsan"，28}};
}
}
parameterizedTest3.java
import org.testng.annotations.Test;
public class parameterizedTest3 {
// 使用數(shù)據(jù)源
@Test(dataProvider = "test")
public void verifyData(String name， int age) {
System.out.println("name:" + name + "，age:" + age);
}
}
testng.xml
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Suite1" verbose="1" >
<test name="Regression1" preserve-order="true">
<classes>
<class name="parameterizedTest3"></class>
</classes>
</test>
</suite>
　　直接運行testng.xml，結(jié)果如下，報錯找不到test的@DataProvider ：

　　修改parameterizedTest3.java，添加dataProviderClass = parameterizedTest2.class屬性，指定數(shù)據(jù)源所在的類
　　import org.testng.annotations.Test;
　　public class parameterizedTest3 {
　　// 使用數(shù)據(jù)源
　　@Test(dataProvider = "test"，dataProviderClass = parameterizedTest2.class)
　　public void verifyData(String name， int age) {
　　System.out.println("name:" + name + "，age:" + age);
　　}
　　}
　　再次運行testng.xml，結(jié)果如下，測試通過：
　　name:dadaorufeng，age:29
　　name:zhangsan，age:28
