Question

我是Junit测试的新手。我正在使用maven surefire插件，struts2-junit-plugin＆amp; junit4.12 用于执行struts2操作类的单元测试用例。以下是POM Entry。

我的Junit Test课程在

之下

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，我收到如下错误。

TestAccountActionUsingStrutsTestCase＆GT; StrutsJUnit4TestCase.setUp：210-＆GT; StrutsJUn it4TestCase.initServletMockObjects：196»NoSuchMethod

请告知如何解决此问题？

Answer 1

NoSuchMethodError表示您的不兼容的依赖版本。尝试通常struts2-junit-plugin从同一struts2-core添加groupId和org.apache.struts个依赖项。

然后也尝试

<!-- 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>
</dependency>

Answer 2

您缺少依赖项

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，模拟对象需要在类路径上。您应该将这些依赖项添加到已部署库中的正确版本控制问题中。
