High-level Use Case Diagram

Functional Requirements Add Credit Type (QS Administrator) User clicks add button and fills presented form New Credit Type saved into Database Usability: no training necessary Reliability: mean time to failure 2% / 10 hrs. Performance: added and displayed <= 5 secs. Supportability (browser): IE, Firefox, Safari, Chrome

Functional Requirements Schedule Appointments (Scheduler) Scheduler request scheduling for appointment list Quota system schedules appointments if possible Usability: 100% returned values understood Reliability: mean time to failure 2% / 10 hrs Performance: request handled <= 3 secs. Supportability: clear, documented code

Dynamic model Algorithm Schedule Appointments Algorithm Sort periods by closest end date Initialize currentTime and goal with appointment date range Iterate through sorted periods list If hole found before period start date Attempt to fill hole with next periods If no hole found Use period quota (add to currentTime) If goal reached, schedule appointment

Testing addCreditType_01 scheduleAppointments_01

Test Case addCreditType_01 Purpose Test if the system successfully adds a new credit type. Test Setup - Empty Database - Insert Policy: - Unlimited 1000, Absolute, Assignable, No Expiration, Start Date: Today, Quota: 1000 - Click on the “Credit Types” tab - Click on the “Add Credit Type” button Input Name: C1 VL Flexible Resource: VIRTUAL LAB Course: C1 Policy: Unlimited 1000 Active: checked, Assignable: checked Expected Output Success message is displayed

Test Case scheduleAppointments_01 Purpose Test if the request successfully adds used_quota for the received appointment. Test Setup - Empty Database - Run (Inset Test Data) SQL script - Prepare scheduleAppointments request Input - appointment: - id = 110 - affiliationId = 123 - username = student4 - resource = CERTIFICATE - course = Course 5 - startTime = 2010-12-24T10:00:00 - endTime = 2010-12-24T11:00:00 Expected Output Valid SOAP response with availabilityStatus set to AVAILABLE
