Cannot import package in unit tests for a Jenkins Shared Library - jenkins

Question

I'm attempting to create unit tests for a JenkinsShared library using Gradle in order to run the test tasks.
I've followed this tutorial which upon conclusion one has a working test suite for a shared library for functions within the vars folder (with the unit tests in src/test/groovy/*Test.groovy).
However, in our internal shared jenkins library we followed a more object oriented style and isolated functionality into a package of classes in the format: src/org/company/*.groovy.
The problem arises when attempting to import said package into a unit test class. In the tutorial, the functions are imported using the loadScript method this method fails when loading a class which is dependent on another file.
Take the class:
package tests
import org.junit.*
import com.lesfurets.jenkins.unit.*
import static groovy.test.GroovyAssert.*
import org.company.UtilFactory
class UtilFactoryTest extends BasePipelineTest {
#Test
void testCall() {
def util = UtilFactory.getUtil("hello")
assertEquals true, true
}
}
src/org/company/UtilFactory.groovy
package org.company
class UtilFactory implements Serializable {
static Util instance
static Util getUtil(script=null) {
if (!(UtilFactory.instance)) {
if (!script) {
// Throws an exception if on the first call to getUtil the
// script parameter is null.
throw new ScriptUndefinedException("script parameter null on initial call to getUtil")
}
UtilFactory.instance = new Util(script)
}
return UtilFactory.instance
}
}
class ScriptUndefinedException extends Exception {
// Parameterless Constructor
public ScriptUndefinedException() {}
// Constructor that accepts a message
public ScriptUndefinedException(String message)
{
super(message);
}
}
Which gives me the exception:
jenkins-utilities/src/test/groovy/UtilFactoryTest.groovy: 7:
unable to resolve class org.company.UtilFactory
# line 7, column 1.
import org.company.UtilFactory
This may be more of a Gradle issue than a JenkinsShared Library. I've just spent a good portion of my day trying to figure out exactly what I'm doing wrong to no avail.
I would really appreciate any help to guide me in the right direction.

This library may be helpful getting your shared libraries to work in the unit test https://github.com/stchar/pipeline-sharedlib-testharness
