[SalesForce] Assert Map> has multiple values in list

I have a method that returns:

Map<String, List<Account>> results

I want to have a test class that asserts that the map contains two list records with one string value. I can't figure out how to do the assertion. I know that with a debug that there are two records in the list.

I tried this:

List<Account> outerList = results.values();
System.assertEquals(2, outerList.size());

and I get the error:

Illegal assignment from List<List<Account>> to List<Account>

I tried this:

System.assertEquals(2, results.values().size());

and I get the result:

Assertion Failed: Expected: 2, Actual: 1

I tried this:

 System.assertEquals(2, results.size());

and I get the result:

Assertion Failed: Expected: 2, Actual: 1

What am I doing wrong?

There's only one key, with two elements, so you'd do:

List<List<Account>> accounts = results.values();
System.assertEquals(1, accounts.size(), 'Map should have one key entry');
System.assertEquals(2, accounts[0].size(), 'List should have two accounts in first key');

[SalesForce] List query results into a string

When you have more that one potential record you cannot access the fields without providing an index. Doing it blindly as such is not advisable and will only get the first record anyway.

[SELECT User__r.FirstName,
                        User__r.LastName
                 FROM NPD_Account_Team__c
                 WHERE Account__c IN :accId
                 ORDER BY User__r.FirstName DESC][0].User__r.FirstName

You should iterate over the records and add them to the string as such:

Set<ID> accId = new Set<Id>();

//Populate accId with values

Map<Id,Set<String>> accountMap = New Map<Id,Set<String>>(); //Ensures no duplicates

for(NPD_Account_Team__c aTeam : [SELECT User__r.FirstName,
                    User__r.LastName
             FROM NPD_Account_Team__c
             WHERE Account__c IN :accId
             ORDER BY User__r.FirstName DESC]){

        Set<String> userSet = accountMap.get(aTeam.Account__c);
        if(userSet == null) userSet = New Set<String>();
        userSet.add(aTeam.User__r.FirstName);
        accountMap.put(aTeam.Account__c,userSet);
     }
    System.debug('usersString is:: ' + string.join(New List<String>(usersSet),','); //Need to convert to list before joining
}

Account[] accTBU = New Account[]{};

for(Id aId : accountMap.keySet()){
     accTBU.add(
         New Account(
                Id=aId,
                USERFIELD = string.join(
                                New List<String>(accountMap.get(aId)),
                                ','
                             )
     );
}

update accTBU;

[SalesForce] Illegal assignment from List to List

Your query returns list of accounts. You cannot assign it to a list of String. Whenever you need field value from any object you need SOQL. Try the below code.

@AuraEnabled
public static string getDunsByRecordId(id currentRecordID) {
    List<Account> accounts = [SELECT Id, DunsNumber 
                              FROM Account  
                              WHERE Id = :currentRecordID 
                              LIMIT 1];
    return (!accounts.isEmpty()) ? accounts[0].DunsNumber : '';
}
