mvn测试中的Struts2 Junit抛出错误

Question

我刚开始做Junit测试。我正在使用maven surefire插件、struts2-junit-plugin & junit4.12来执行struts2动作类的单元测试用例。下面是POM条目。

 <!-- https://mvnrepository.com/artifact/junit/junit -->
    <dependency>

我的Junit测试类在下面

package au.com.replenishment.galaxy.testcase;

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;

import org.apache.struts2.StrutsJUnit4TestCase;
import org.junit.Test;

import com.opensymphony.xwork2.ActionProxy;

import au.com.replenishment.galaxy.web.actions.implementation.AccountAction;

public class TestAccountActionUsingStrutsTestCase  extends StrutsJUnit4TestCase<Object>{
    
     @Test  
     public void testUserNameErrorMessage() throws Exception {
         
            request.addParameter("accountBean.userName", "Bruc");
            request.addParameter("accountBean.password", "test");
     
            ActionProxy proxy = getActionProxy("/createaccount");
     
            AccountAction accountAction = (AccountAction) proxy.getAction();
     
            proxy.execute();
     
            assertTrue("Problem There were no errors present in fieldErrors but there should have been one error present", accountAction.getFieldErrors().size() == 1);
            assertTrue("Problem field account.userName not present in fieldErrors but it should have been",
                    accountAction.getFieldErrors().containsKey("accountBean.userName") );
     
        }
     
        @Test  
        public void testUserNameCorrect() throws Exception {
            request.addParameter("accountBean.userName", "Bruce");
            request.addParameter("accountBean.password", "test");
     
            ActionProxy proxy = getActionProxy("/createaccount");
     
            AccountAction accountAction = (AccountAction) proxy.getAction();
     
            String result = proxy.execute();
     
            assertTrue("Problem There were errors present in fieldErrors but there should not have been any errors present", accountAction.getFieldErrors().size() == 0);
            assertEquals("Result returned form executing the action was not success but it should have been.", "success", result);
     
        }
}

但是在执行测试时，我得到的是错误：

下面是错误消息。

请建议如何解决这一问题？

Answer 1

您缺少依赖项。

• junit 4.12
• org.apache.struts支柱2-弹簧-插件(可选) 2.5.8
• org.springframework弹簧-测试4.1.6 4.3.6
• org.springframework弹簧-核心4.1.6 4.3.6
• org.springframework spring-上下文4.1.6.context 4.3.6.context

运行测试时需要在类路径上运行的模拟对象。您应该添加这些依赖项来纠正已部署库中的版本控制问题。

Answer 2

NoSuchMethodError意味着不兼容的依赖关系版本。尝试从相同的struts2-junit-plugin和struts2-core依赖项(通常是org.apache.struts )中添加它们。

那也试试
