Thanks for the reply. You are certainly welcome to take a look:

Test Method:

static testMethod void testSolution(){ //First, prepare 20 solutions for the test data Solution[] SolutionsToCreate = new Solution[]{}; for(Integer x=0; x<20;x++){ Solution s = new Solution(SolutionName='test',SolutionNote='test'); SolutionsToCreate.add(s); } Case[] CasesToCreate = new Case[]{}; for(Integer x=0; x<20;x++){ Case c = new Case(Subject='test',Description='test',Feature_Area__c='Alarms',Status = 'PCR Submitted'); CasesToCreate.add(c); } //Now insert data causing solution triggers to fire. Test.startTest(); insert casesToCreate; insert solutionsToCreate; CategoryData[] CategoryDatasToCreate = new CategoryData[]{}; for(Integer x=0; x<20;x++){ CategoryData cs = new CategoryData(RelatedSobjectId=SolutionsToCreate[x].id,categorynodeid='02n80000000EP8ZAAW'); CategoryDatasToCreate.add(cs); } insert CategoryDatasToCreate; CaseSolution[] CaseSolutionsToCreate = new CaseSolution[]{}; for(Integer x=0; x<20;x++){ CaseSolution cs = new CaseSolution(CaseId=CasesToCreate[x].id,SolutionId=SolutionsToCreate[x].id); CaseSolutionsToCreate.add(cs); } insert caseSolutionsToCreate; for(Integer x=0; x<20;x++){ SolutionsToCreate[x].isPublished = true; } update SolutionsToCreate; Test.stopTest(); }

 Solution category method:

public static void AssignSolutionCategory(solution[] solutions) { Map<Id,string> solutionCaseMap = New Map<Id,string>(); List<string> solutionIdList = New List<string>(); for (CaseSolution cs : [Select SolutionId,CaseId from casesolution where SolutionId in :solutions]) { //I do this to ensure I only have one case match per solution if (solutionCaseMap.containsKey(cs.SolutionId)==false) { solutionCaseMap.put(cs.SolutionId,cs.CaseId); solutionIdList.add(cs.SolutionId); } } If (solutionCaseMap.size() > 0) { Map<Id,string> caseFeatureAreaMap = New Map<id, string>(); for (Case c : [Select Id,Feature_Area__c from case where id in (Select CaseId from casesolution where SolutionId in :solutionCaseMap.keySet())]) { caseFeatureAreaMap.put(c.id, c.Feature_Area__c); } List<CategoryNode> categoryNodeList = New List<CategoryNode>(); for (CategoryNode cn : [Select Id,MasterLabel from categorynode]) { categoryNodeList.add(cn); } List<CategoryData> category = New List<CategoryData>(); for (integer x = 0; x < categoryNodeList.size(); x++) { for (integer i = 0; i < solutionIdList.size(); i++) { If (caseFeatureAreaMap.get(solutionCaseMap.get(solutionIdList[i])) == categoryNodeList[x].MasterLabel) { CategoryData cd = new CategoryData(); cd.CategoryNodeId = categoryNodeList[x].id; cd.RelatedSobjectId = solutionIdList[i]; category.add(cd); } } } insert category; } }
