public static void insertException(Map<string, string> param)
    {    
    Exception__c newExcept              =   new Exception__c();
        newExcept.ExceptionTypeCode__c      =   param.get('ExceptionTypeCode__c');
        newExcept.RecordType.DeveloperName  =   'New Exception'; 


test class

    @isTest(SeeAllData=true)
    public class TestExceptionCreateExceptionRecord {
       static testmethod void Exception(){
        map<String ,String> parm=new map<String,String>();
            parm.put('ExceptionTypeCode__c', 'open');                
            parm.put('entry2','Second entry');

Is this still an open question? You mentioned in some of the questions that your problem was solved but never accepted an answer... — Adrian Larson

Not entirely clear from the other answers/comments that this is solved yet. The key point is that to set a record type you must relate the object to an already existing RecordType object by setting that already existing RecordType object's ID in the RecordTypeId field:

List<RecordType> rts = [
        SELECT Id FROM RecordType
        WHERE SobjectType = 'Exception__c'
        AND DeveloperName = 'New_Exception'
        ];
newExcept.RecordTypeId = rts[0].Id;

In this example you are trying to access RecordType's attribute DeveloperName before even its declared.

newExcept.RecordType.DeveloperName = 'New Exception';

First set the RecordType for the newExcept, then try setting the DeveloperName
I am not sure why you are using RecordType.DeveloperName to set the Exception Name. It would be better to add a field in Exception__c called DeveloperName.

List<RecordType> lstRecordType = [SELECT id FROM RecordType WHERE SobjectType = 'Exception__c' AND DeveloperName = 'New_Exception']; newExcept.RecordType.DeveloperName = 'New Exception';
