Hi Lauren,

You can take reference from this below code. 
@isTest
public class TestControllerExtension_Test {
    @istest static void test(){
        Test2__c tes= new Test2__c();
        tes.name='Sample';
        tes.Test2_First_Name__c='Rahul'';
        tes.Test2_Last_Name__c='Singh';
        tes.Test2ReportDate__c=date.today();
        tes.Test2_Middle_Name__c='Kumar';
        //put the remaining fields if you have to need
        insert tes;
        test.startTest();
        PageReference pageRef = new PageReference('/apex/VFPage');
        pageRef.getParameters().put('RequestID' , tes.id);
        Test.setCurrentPageReference(pageRef);
        TestControllerExtension ce= new TestControllerExtension();
        ce.getcca();
        ce.NextPage();
        ce.PreviousPage();
        test.stopTest();
    }
}
