I am a beginner at this, and have a fairly basic Trigger I am using.  It is achieving 94% code coverage (16/17).  When I try to deploy to production it fails with an error message of 0% code coverage.  Not sure how to increase to at least 1%.
Below is both my Trigger code and Apex Class Test code:

TRIGGER CODE:

trigger LeadConvert on Lead (after insert) {
 
    list<database.leadconvert> leadsToConvert = new list<database.leadconvert>();
    Database.LeadConvert lc;
    string convertedStatus = '';
    list<leadstatus> convertStatusList = new list<leadstatus>();
    convertStatusList = [Select Id, MasterLabel
                            from LeadStatus
                            where IsConverted=true limit 1];
    if(convertStatusList.size() > 0){
        convertedStatus = convertStatusList[0].MasterLabel;
    }else{
        convertedStatus = 'Closed - Converted';
    }
     
    for(Lead l : trigger.New){
        if(l.LeadSource == 'Web'){
            //This lead should be converted automatically to a Contact/Account
            lc = new database.LeadConvert();
            lc.setLeadId(l.ID);
            lc.setDoNotCreateOpportunity(true);
            lc.setConvertedStatus(convertedStatus);
            leadsToConvert.add(lc);
        }
    }
     
    list<database.leadconvertresult> lcrList = new list<database.leadconvertresult>();
    lcrList = Database.convertLead(leadsToConvert);
}


APEX CLASS TEST CODE:

@IsTest
public class TestConvertLead {
    static testmethod void convertLead() {
    
        Lead l = new Lead();
        
        l.FirstName = 'Jane';
        l.LastName = 'Doe';
        l.Company = 'Onassis Foundation (USA)';
        l.Email = 'senvas@aol.com';
        l.LeadSource = 'Web';
        
        insert l;
    }
}
