Hi All,
we want to activate the chatter for email to case in lightning but we do not want any person to post or comment using chatter.
I have written two triggers for not posting anything and also commenting via case feed both are working fine but failed to write a test classes for both.
FeedItem:
trigger ChatterCommentItem on FeedItem (before insert) {
for(FeedItem fi : trigger.new)
        if(fi.type == 'ContentPost' || fi.type == 'TextPost')
            fi.addError('you do not have permissions to post any comment or File.Please contact your system administrator.');
}
FeedComment
trigger ChatterComment on FeedComment (Before Insert) { 
    for(FeedComment fc : trigger.new)
if(fc.CommentType == 'ContentComment' || fc.CommentType == 'TextComment' )
            fc.addError('you do not have permissions to post any comment or File.Please contact your system administrator.');
}

I have written feed comment trigger for case object when the case status or any changes happens case feed is generated so no one should comment on it any help on the test classes for both triggers would be appriciated thank you.

I am using &nbsp I do not want to use it and also why I am getting the alignment issue below is the code nad output thanks.

I have implemented "liveAgent:clientChatQueuePosition" tag in a customized chat window to show the user at what place he is in Queue. When the request has been sent to the agent, however, the value is null. Do anyone let me know how when the queue position is zero another conditional message is displayed?
<tr>
 <td>
  <p style="font-size: 14px;">You are now being connected to an agent. Currently your position in the queue is <liveAgent:clientChatQueuePosition /></p>
 </td>

Hi
Looking forward for help on below trigger I am new to salesforce and unable to achieve code coverage any help would be helpful thanks.
