Help me out to Cover Trigger

Please Help me out to cover Trigger to achieve 100 % Code Coverage.

Trigger:
  
trigger FireEmailWithEmailTemplate on Email_Template__c (after insert) {
    
    set <id> RuleID = new set<Id> ();
    for (Email_Template__c e : trigger.new)
    {
        RuleID.add(e.GDPR_Rule__c);
    }
    
    List<Contact> con = [SELECT FirstName, LastName, Email FROM Contact WHERE Id IN (SELECT Contact__c FROM Assigned_Communication_Rule__c WHERE OptinCommunicationMethod__c IN : RuleID )];
    
	for (contact c : con)
    {
        for (Email_Template__c em : trigger.new)
        {
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();                   
            mail.setToAddresses(new String[] {c.Email}); 
            mail.setSubject(em.Subject__c); 
            mail.setUseSignature(false);
            mail.setHtmlBody('Hello'+ c.FirstName+' ' + c.LastName+', <br><br> '+em.Email_Body__c+ ' <br> Regards, <br><br> Admin Team'); 
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });  
        }
    }
}

Test Class
  
@isTest
public class Test_FireEmailWithEmailTemplate {
    
    static testMethod void EmailTemplate1()
    {
      
        Contact c = new Contact ();
        c.LastName = 'test';
        c.FirstName = 'test';
        c.Email = 'test@test.com';
        insert c;
        
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();                   
        mail.setToAddresses(new String[] {c.Email}); 
        mail.setSubject(em.Subject__c); 
        mail.setUseSignature(false);
        mail.setHtmlBody('Hello'+ c.FirstName+' ' + c.LastName);
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });  
        
    }
    
    
}

I have tried your code with all the mandatory fields but still, my code coverage is not increasing.

This is not covered yet. 
for (contact c : con)
    {
        for (Email_Template__c em : trigger.new)
        {
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();                   
            mail.setToAddresses(new String[] {c.Email}); 
            mail.setSubject(em.Subject__c); 
            mail.setUseSignature(false);
            mail.setHtmlBody('Hello'+ c.FirstName+' ' + c.LastName+', <br><br> '+em.Email_Body__c+ ' <br> Regards, <br><br> Admin Team'); 
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });  
        }
    }

Thanks
