JUnit test fails with JMockit java.lang.IllegalStateException: Invalid context for writing expectations

@Test
public void testGetOnlyNewPartitions() throws Exception {
    setUp();
    new Expectations(){
        HiveUtil hiveUtil;
        {
            HiveUtil.getInstance(); returns(hiveUtil);
            hiveUtil.getAllpartitions(oldTable); returns(oldPartitions);
            hiveUtil.getAllpartitions(newTable); returns(newPartitions);
        }
    };
    PartitionFilter partitionFilter = new PartitionFilter(oldTable, newTable, HiveUtil.getInstance());
}

      

        
        
        
      

    

I am testing a module of the PartitionFilter class that uses the HiveUtil singleton class.

In my test case, the error was "java.lang.IllegalStateException: Invalid context for writing expectations" while running. Any explanation as to why this is happening?

This is the important part of my pom.xml:

<dependency>
         <groupId>org.jmockit</groupId>
         <artifactId>jmockit</artifactId>
         <version>1.13</version>
</dependency>

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
</dependency>

      

        
        
        
      

    

I tried to install the jmockit dependency before the junit dependency in the pom. It didn't work.

Some more research showed that I did not use the @RunWith (JMockit.class) annotation at the beginning of the class. However, when I tried to use it, I was presented with the error "Class cannot be resolved to type". I've done all the relevant imports.

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.*;

import mockit.*;
import mockit.integration.junit4.*;
import junit.framework.TestCase;

      

        
        
        
      

    

What am I doing wrong?
