[FIXED] Struts2 Junit case throwing error during mvn test

Issue

I am new to Junit testing. I am using maven surefire plugin, struts2-junit-plugin & junit4.12 for to executing unit test cases for struts2 action classes. Below is the POM Entry.

 <!-- https://mvnrepository.com/artifact/junit/junit -->
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
    </dependency>
        <!-- https://mvnrepository.com/artifact/org.hamcrest/hamcrest-core -->
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-core</artifactId>
        <version>1.3</version>
    </dependency>
    <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-junit-plugin</artifactId>
        <version>2.3.4</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>au.com.mercury.lib</groupId>
        <artifactId>struts2-core</artifactId>
        <version>2.3.4</version>
    </dependency>
     <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <dependencies>
              <dependency>
                <groupId>org.apache.maven.surefire</groupId>
                <artifactId>surefire-junit47</artifactId>
                <version>2.19.1</version>
              </dependency>
            </dependencies>
            <configuration>
              <parallel>methods</parallel>
              <threadCount>10</threadCount>
            </configuration>
    </plugin>

And my Junit Test class is below

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);
     
        }
}

But when executing the test, I am getting the error:

Below is the error message.

Please advice how to resolve this issue ?

Solution

You are missing dependencies

• junit » junit 4.12
• org.apache.struts » struts2-spring-plugin (optional) 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

Mock objects required to be on classpath when running tests. You should add these dependencies to correct versioning problem in your deployed libraries.
