mvn测试期间的Struts2 Junit案例抛出错误

Question

我是 Junit 测试的新手。我正在使用 maven surefire plugin, struts2-junit-plugin & junit4.12 来执行 struts2 动作类的单元测试用例。以下是 POM 条目。

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，我得到了错误：

以下是错误信息。

请指教如何解决这个问题？

Answer 1

你缺少依赖项

• junit » junit 4.12
• org.apache.struts » struts2-spring-plugin（可选）2.5.8
• org.springframework » spring-test 4.1.6.RELEASE 4.3.6.RELEASE
• org.springframework » spring-core 4.1.6.RELEASE 4.3.6.RELEASE
• org.springframework » spring-context 4.1.6.RELEASE 4.3.6.RELEASE

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

Answer 2

NoSuchMethodError 表示您的依赖版本不兼容。尝试从相同的 groupId 添加 struts2-junit-plugin 和 struts2-core 依赖项，通常是 org.apache.struts。

那也试试

<!-- https://mvnrepository.com/artifact/org.apache.struts/struts2-spring-plugin -->
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>2.3.4</version>
