import static org.junit.Assert.assertEquals ; import org.databene.benerator.anno.Source; import org.databene.feed4junit.Feeder; import org.junit.Test; import org.junit.runner.RunWith; import sample.junit.code.*; @RunWith (Feeder.class ) public class Feed4junitSample { @Test @Source( "Data.csv" )//CSV source public void testAccessCheck_CSV(String userName, String pw, boolean expected) { assertEquals(expected, UserAccess. accessCheck(userName, pw)); } @Test @Source( "data.xls" )//Excel source public void testAccessCheck_Excel(String userName, String pw, boolean expected) { assertEquals(expected, UserAccess. accessCheck(userName, pw)); } } |
运行结果如下:
3、数据库作为数据源
同样,Feed4junit也支持数据库数据源,这里不做详细的介绍:其原理和上面文件数据源差不多,样例代码如下:
类上声明@Database:
import static org.junit.Assert.assertEquals; import org.databene.benerator.anno.Database; import org.databene.benerator.anno.Source; import org.databene.feed4junit.Feeder; import org.junit.Test; import org.junit.runner.RunWith; import sample.code.UserAccess; /* * Feed4JUnit - Get Data from Database, all test methods can use the database data */ @RunWith(Feeder.class) @Database( id = "testdb", url = "jdbc:mysql://localhost:5000/SAMPLE", driver = "com.mysql.jdbc.Driver", user = "admin", password = "admin") public class F4JfromDB { @Test @Source(id = "testdb", selector = "select * from TEST") public void testAccessCheck(String userName, String pw, String expected) { Boolean bSucess = UserAccess.accessCheck(userName.trim(), pw.trim()); assertEquals(expected.trim(), bSucess.toString()); } } |
测试方法上声明@Database
@RunWith(Feeder.class) public class F4JfromDB_Method { @Test @Database( id = "testdb", url = "jdbc:mysql://localhost:5000/SAMPLE", driver = "com.mysql.jdbc.Driver", user = "admin", password = "admin") @Source(id = "testdb", selector = "select * from TEST") public void testAccessCheck(String userName, String pw, String expected) { Boolean bSucess = UserAccess.accessCheck(userName.trim(), pw.trim()); assertEquals(expected.trim(), bSucess.toString()); } } |
测试运行过程中,通过 url,driver 等信息建立数据连接,通过 selector 发出数据请求,最后完成查询并把数据传递给测试方法,数据在传递给方法的时候,会按数据表的列的顺序与参数进行匹配.
4、最后
Feed4JUnit 提供了对数据与代码分离的测试支持。只需要简单的注释,Feed4JUnit 就可以使用户很方便的实施数据与代码分离之间的测试,对于习惯了JUnit 测试框架的同学来说,是一个十分省力的利器。
Feed4JUnit 同时还提供大量数据的随机测试和等价类测试等众多功能,这个留到后面再进行挖掘。
