How to write a Test Class for @InvocableMethod

I'm having an issue with "Method does not exist or incorrect signature" on this test class...



Public class AutoConvertLeads
{
    @InvocableMethod
    public static void LeadAssign(List<Id> LeadIds)
    {
        LeadStatus CLeadStatus= [SELECT Id, MasterLabel FROM LeadStatus WHERE IsConverted=true Limit 1];
        List<Database.LeadConvert> MassLeadconvert = new List<Database.LeadConvert>();
        for(id currentlead: LeadIds){
                Database.LeadConvert Leadconvert = new Database.LeadConvert();
                Leadconvert.setLeadId(currentlead);                
                Leadconvert.setConvertedStatus(CLeadStatus.MasterLabel);
                MassLeadconvert.add(Leadconvert);
        }
        
        if (!MassLeadconvert.isEmpty()) {
            List<Database.LeadConvertResult> lcr = Database.convertLead(MassLeadconvert);
        }
    }
}





@isTest
private class AutoConvertLeadsTest {
    @isTest
    public static void testLeadInsert ()
    {
        List<Id> lListIds = new List<Id>();
        List<Lead> lList = new List<Lead>();
        
        Lead objLead = new Lead (LastName = 'Test', Email = 'test@gmail.com', mobilephone = '+1234567890', Company = 'Test company');
        insert objLead; 
        
        lList = [SELECT Id FROM Lead];
        
        for(Lead l : lList){
            lListIds.add(l.Id);
        }
        
        insert lList;
        
        Test.startTest();
        AutoConvertLeadsTest.LeadAssign(lListIds);
        Test.stopTest();
    }
}

Hello Jeff,
Hope that your day is off to an amazing start. Your issue stems from a class not being instantiated. Please try the below test class and report back when you get the chance. Hope this helps and may God bless you abundantly. 
@isTest
private class AutoConvertLeadsTest {
    @isTest
    public static void testLeadInsert ()
    {
        AutoConvertLeads convert = new AutoConvertLeads();
        List<Id> lListIds = new List<Id>();
        List<Lead> lList = new List<Lead>();
        
        Lead objLead = new Lead (LastName = 'Test', Email = 'test@gmail.com', mobilephone = '+1234567890', Company = 'Test company');
        insert objLead; 
        
        lList = [SELECT Id FROM Lead];
        
        for(Lead l : lList){
            lListIds.add(l.Id);
        }
        
        insert lList;
        
        Test.startTest();
        convert.LeadAssign(lListIds);
        Test.stopTest();
    }
}


Best Regards,

Hi Anthony, thanks so much for the kind response! What would happen when I receive the "InvocableMethod methods must be declared as static" in the class itself?
