Hi there!
I am new to Apex, but would like to deploy the following Apex code to my org. The issue however is that I don't know how to write unit tests. Can anyone assist?

trigger UpdateCaseCommentFields on FeedItem (after insert) {
List<Case> updates = new List<Case>();
for (FeedItem fi : Trigger.new) {
if (fi.ParentId.getSObjectType() == Case.SObjectType && fi.Visibility == 'InternalUsers') {
updates.add(new Case(
Id = fi.ParentId,
Last_Internal_Comment__c = fi.Body
));
}
else if (fi.ParentId.getSObjectType() == Case.SObjectType && fi.Visibility != 'InternalUsers') {
updates.add(new Case(
Id = fi.ParentId,
Last_External_Comment__c = fi.Body
));
}
}
update updates;
}
First need to put a validation in your code to check the size of list updates list.
And Need to write test class for +ive and -ive cases.
@isTest private class UpdateCaseCommentFieldsTest { static testMethod void myUnitTest1() { Case caseObj = new Case (Status = 'Open', Priority = 'Low', Origin = 'Email'); insert caseObj; Test.startTest(); FeedItem feed = new FeedItem (); feed.ParentId = caseObj.Id; feed.Body = 'Hello Internal'; feed.Visibility = 'InternalUsers'; insert feed; feed = new FeedItem (); feed.ParentId = caseObj.Id; feed.Body = 'Hello All'; feed.Visibility = 'AllUsers'; insert feed; //if you can user system assert than it will be good test.stopTest(); } static testMethod void myUnitTest2() { Case caseObj = new Case (Status = 'Open', Priority = 'Low', Origin = 'Email'); insert caseObj; Test.startTest(); FeedItem feed = new FeedItem (); feed.ParentId = caseObj.Id; feed.Body = 'Hello Internal'; feed.Visibility = 'InternalUsers1'; insert feed; feed = new FeedItem (); feed.ParentId = caseObj.Id; feed.Body = 'Hello All'; feed.Visibility = 'AllUsers1'; insert feed; Test.stopTest(); } }-Thanks
