//Scenario:
//The goal is to test what happens when an email is sent through Salesforce.
//Simulate this in the test by creating a task with Subject that starts with 'Email:' on a contact
//Expected Result:
    //New Follow up Task created and attached to contact

    static testMethod void createEmailTask() {
        Contact newman = new Contact (LastName='Newman');
        insert newman;

        insert newEmail;
        
       //check that the follow up task exists
       
        List <Task> task_afteremail = [SELECT Subject, WhoId, ActivityDate FROM Task WHERE WhoId = :newman.Id AND Subject = 'Follow Up on: Email: Dude, where is my car?'];
        system.assert(task_afteremail.size()==1);
        
        //TODO: Other tests to try: cover the situations when we do NOT want a task created, also when many emails at once are created.
