[英]InvocationTargetException in Easy mock of JUnit
I am facing an issue while running JUnit
using EasyMock
. 使用EasyMock
运行JUnit
时遇到问题。 Please find below the source files - UserTest.java
(JUnit file) and UserFinder.java
(Application file to be unit tested). 请在下面找到源文件UserTest.java
(JUnit文件)和UserFinder.java
(要进行单元测试的应用程序文件)。
UserTest.java UserTest.java
Class UserTest
{
...
@Test
public void testFindUserFunction() throws Exception {
DAO daoMock = EasyMock.createMock(DAO.class);
User user = new User("john", "stephen", "city street", "bangalore");
EasyMock.expect(daoMock.userExists(user).andReturn(true);
EasyMock.replay(daoMock);
String userFirstName = user.getFirstName();
User resultUser = UserFinder.findUser(userFirstName, daoMock);
PowerMock.verify(daoMock);
Assert.assertEquals(user, resultUser);
}
}
UserFinder.java UserFinder.java
Class UserFinder {
...
...
public User findUser(String userFirstName, DAO dao)
{
return dao.findUser(userFirstName);
}
...
...
}
In JUnit, I have created a mock object daoMock
and added below expect
behavior. 在JUnit中,我创建了一个模拟对象daoMock
并添加了以下expect
行为。
EasyMock.expect(daoMock.userExists(user).andReturn(true);
In the below line of UserFinder.java , I need to pass daoMock
as the class is already existing and designed in that way. 在UserFinder.java的 daoMock
行中,我需要传递daoMock
因为该类已经存在并且已经通过这种方式进行了设计。 When the below line is executed through JUnit, I am getting java.lang.reflect.InvocationTargetException
. 通过JUnit执行下面的行时,我正在获取java.lang.reflect.InvocationTargetException
。
User resultUser = UserFinder.findUser(userFirstName, daoMock);
I am new to EasyMock
and I thought setting expect
adds to the behavior of the daoMock
object but it is not. 我是EasyMock
新手,我认为设置expect
会增加daoMock
对象的行为,但事实并非如此。 Please help me about how to call dao.findUser
line as I cannot mock this line since it is in application file. 请帮助我有关如何调用dao.findUser
行,因为该行位于应用程序文件中,因此我无法模拟此行。 How can I mock and run the JUnit for this case in EasyMock
. 在EasyMock
如何为这种情况模拟并运行JUnit。 Thanks. 谢谢。
You must mock the method 您必须模拟该方法
EasyMock.expect(dao.findUser(userFirstName).andReturn(user);
instead of 代替
EasyMock.expect(daoMock.userExists(user)).andReturn(true);
