Hi everyone,I am new to salesforce and I'm having trouble with a test class. I'm passing a value to the target class variable but when the SOQL query executes, it returns "System.QueryException: List has no rows for assignment to SObject". Please help

I have a custom object namend tpdDatabase. I have an Apex class with the method below to get an instance of this object (by databasename). 

The line "tpdDatabase__c tpDatabase = tpdDatabase__c.getValues(databaseName);" produces this error:

Not of type Custom Settings

I don't quite understand what goed wrong here. Could anyone point me in the right direction? Many thanks in advance!

    public tpdDatabase__c getByDatabaseName(String databaseName) {
        
        tpdDatabase__c tpDatabase = tpdDatabase__c.getValues(databaseName);
        if (tpDatabase == null) {
        return null;
        }
        return tpDatabase; 
    }

Hi All,

I've followed a tutorial about excluding specific domains in email to case, so that if an email from a specific domain is sent to the email2case email, a case won't get created. The application works great in Sandbox but I am struggling to move it to production as the test class seems to require some test entry for the custom metadata type and I am not really sure how to include that in the test class. 

Trigger:

//Tins trigger wiLL. be used to KiLL emaiLs coming via E2C and with certain domain names 2 
trigger AutoE2CCaseDeletion on Case (before insert) { 
    System.debug('Entered Kill Case trigger'); 
    SSK_RestrictedE2CDomains.killEmailToCase(Trigger.New); 
}

Here is the main class:

public with sharing class SSK_RestrictedE2CDomains {
	private static String SSK_RestrictedE2CDomains {
	get{
		return 'Restriced_E2C_Domains';
		
	}
}

private static Set<String> getSupportSetting(String settingName){
	Support_Setting__mdt supportSetting = [
	SELECT Value__c
	FROM Support_Setting__mdt
	WHERE DeveloperName = :settingName
	];
	

	Set<String> settingValues = new Set<String>();

	//settingValues.addAll(supportSetting.Value__c.split(','));
	return settingValues;
}

//Method to kiLL EmaiLs coming in from restricted Domains (E2C) 
public static void killEmailToCase (List<Case> lstCases){ 
	System.debug('killEmailToCase method successfully called'); 
	for(Case newCase: lstCases){ System.debug('Case ID: ' + newCase.Id); 
	System.debug('Case Origin: ' + newCase.Origin); 
	System.debug('Case From/Supplied/Web Email: ' + newCase.SuppliedEmail); 
	System.debug('Record Type name is: ' + newCase.RecordType.DeveloperName); 


//Read the "Restricted E2C Domains" from the Custom Metadata Types Labelled "Support Settings" 
Set<String> restrictedE2CDomains = getSupportSetting(SSK_RestrictedE2CDomains); 
if(newCase.SuppliedEmail != NULL && newCase.SuppliedEmail != 'email2casesmith@gmail.com'){ 
if(newCase.Origin == 'Email' && newCase.SuppliedEmail != NULL && newCase.SuppliedEmail.contains('@')) { 
//SpLit the EmaiL with DeLimiter as 1@' 
//So john.doe@gmaiL.com returns a List - ['fijohn.doe', 'gmaiL.com'] 
//Here the second index wiLL point to the Domain Name which is [1] 
List<String> emailParts = newCase.SuppliedEmail.split('@'); 
if(restrictedE2CDomains.contains(emailParts[1])){ 
	System.debug('Problematic case found and shouldnt be created'); 
	newCase.addError('Creation of cases with these domains are not allowed'); 
} 
} 
} 
} 
}		
}

TestClass1

@isTest 
private class tstE2CDomainNoKill {
	static testMethod void notKillCaseE2C_valid_domain(){

	Account newAcc = new Account();
	newAcc.Name = 'Test Account';
	Insert newAcc;

	Case newCase = new Case();
	newCase.AccountId = newAcc.Id;
	newCase.SuppliedEmail = 'test@gmail.com';
	newCase.Origin = 'Email';
	Insert newCase;
	System.assertNotEquals(NULL, newCase.Id);

	Case newCase2 = new Case();
	newCase.AccountId = newAcc.Id;
	newCase.SuppliedEmail = 'email2casesmith@gmail.com';
	newCase.Origin = 'Email';
	Insert newCase2;
	System.assertNotEquals(NULL, newCase2.Id);


		
	}
}

The above test class does fail and show the following text:

System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, AutoE2CCaseDeletion: execution of BeforeInsert

caused by: System.QueryException: List has no rows for assignment to SObject

Class.SSK_RestrictedE2CDomains.getSupportSetting: line 10, column 1
Class.SSK_RestrictedE2CDomains.killEmailToCase: line 33, column 1
Trigger.AutoE2CCaseDeletion: line 4, column 1: []

Any help/suggestion would highly be appreciated.

Thanks!

 

Hi Guys,
getting variable does not exist when checking the old value is null or not. please suggest

 public static Boolean HasAccess(List<AccountContactRelation> lstNew) {
               for (AccountContactRelation acr : lstNew) {
                system.debug('trigOld-->'+trigger.oldMap.get(acr.Id));
                
                    if(string.isNotBlank(acr.Entity__c) || string.isNotBlank(trigger.oldMap.get(acr.Id).External_Entity__c)  ){// getting  error on this line checking oldmap
                    
                        if(acr.External_Entity__c != 'Customer-facing')
                            throw new acrException(System.Label.Cimited);
                    }
                }
                  return bReturn;
            }
       

I am working on optimizing code that I didn't originally write. 
Each object has multiple triggers, and each trigger has soql queries.
There is a trigger that is hitting the limit for soql queries. Is there an easy way to pinpoint where these queries are?

Hi everyone,I am new to salesforce and I'm having trouble with a test class. I'm passing a value to the target class variable but when the SOQL query executes, it returns "System.QueryException: List has no rows for assignment to SObject". Please help
