EasyMock
简介
准备
1.获取J2SDK;
2. 获取JUnit V3.8.1(从http://www.junit.org获取开发包);
3.获取EasyMock V1.1(从http://www.easymock.org获取EasyMock开发包)。
4.为了开发方便，建议使用一个好IDE。以下例子中的代码均是在Eclipse V3.0环境下进行的调试。
例子一
以下是一个简单例子，为了方便对比，这里重新实现了JMock例子一，代码如下：
package test1;
import org.easymock.*;
import junit.framework.*;
import javax.servlet.http.*;
public class MockRequestTest extends TestCase{
private MockControl control;
private HttpServletRequest mockRequest;
public void testMockRequest(){
//创建一个Mock HttpServletRequest的MockControl对象
control = MockControl.createControl(HttpServletRequest.class);
//获取一个Mock HttpServletRequest对象
mockRequest = (HttpServletRequest) control.getMock();
//设置期望调用的Mock HttpServletRequest对象的方法
mockRequest.getParameter("name");
//设置调用方法期望的返回值，并指定调用次数
//以下后两个参数表示最少调用一次，最多调用一次
control.setReturnValue("kongxx" ,1 ,1);
//设置Mock HttpServletRequest的状态，
//表示此Mock HttpServletRequest对象可以被使用
control.replay();
//使用断言检查调用
assertEquals("kongxx",mockRequest.getParameter("name"));
//验证期望的调用
control.verify();
}
}
import org.easymock.*;
import junit.framework.*;
import javax.servlet.http.*;
public class MockRequestTest extends TestCase{
private MockControl control;
private HttpServletRequest mockRequest;
public void testMockRequest(){
//创建一个Mock HttpServletRequest的MockControl对象
control = MockControl.createControl(HttpServletRequest.class);
//获取一个Mock HttpServletRequest对象
mockRequest = (HttpServletRequest) control.getMock();
//设置期望调用的Mock HttpServletRequest对象的方法
mockRequest.getParameter("name");
//设置调用方法期望的返回值，并指定调用次数
//以下后两个参数表示最少调用一次，最多调用一次
control.setReturnValue("kongxx" ,1 ,1);
//设置Mock HttpServletRequest的状态，
//表示此Mock HttpServletRequest对象可以被使用
control.replay();
//使用断言检查调用
assertEquals("kongxx",mockRequest.getParameter("name"));
//验证期望的调用
control.verify();
}
}
编译并将其当做一个Test Case运行，会发现两个测试方法均测试成功。
例子二
同例子一样，对JMock例子二重新实现产生了EasyMock的例子二。
需要测试的类代码如下：
package test2;
import javax.servlet.http.*;
public class MyClass {
public String getName(HttpServletRequest request) {
return request.getParameter("name");
}
public String getPassword(HttpServletRequest request) {
return request.getParameter("password");
}
}
import javax.servlet.http.*;
public class MyClass {
public String getName(HttpServletRequest request) {
return request.getParameter("name");
}
public String getPassword(HttpServletRequest request) {
return request.getParameter("password");
}
}
测试类代码如下：
package test2;
import org.easymock.*;
import junit.framework.*;
import javax.servlet.http.*;
public class TestMyClass extends TestCase{
private MockControl control;
private HttpServletRequest mockRequest;
private MyClass myclass ;
public void setUp() {
myclass = new MyClass();
//创建一个Mock HttpServletRequest的MockControl对象
control = MockControl.createControl(HttpServletRequest.class);
//获取一个Mock HttpServletRequest对象
mockRequest = (HttpServletRequest) control.g
import org.easymock.*;
import junit.framework.*;
import javax.servlet.http.*;
public class TestMyClass extends TestCase{
private MockControl control;
private HttpServletRequest mockRequest;
private MyClass myclass ;
public void setUp() {
myclass = new MyClass();
//创建一个Mock HttpServletRequest的MockControl对象
control = MockControl.createControl(HttpServletRequest.class);
//获取一个Mock HttpServletRequest对象
mockRequest = (HttpServletRequest) control.g
