- Verify that control panel buttons are responsive to touch and provide immediate feedback.
- Verify that the floor indicators are clearly visible and easy to read from a distance.
- Verify that braille labels are provided alongside floor buttons for visually impaired passengers.
- Verify that the elevator provides audio announcements for floor numbers and emergency instructions.
- Verify that the control panel is reachable and usable for passengers with disabilities.
Boundary Conditions Test Cases
Boundary tests evaluate the elevator’s performance under extreme conditions.
- Verify that the elevator operates smoothly at maximum weight capacity.
- Verify that the elevator responds within an acceptable time frame during peak usage hours.
- Verify that the elevator functions correctly during power fluctuations and restores operation when power is restored.
- Verify that the emergency lighting system activates immediately in case of power outage.
- Verify that the elevator maintains functionality in extreme temperatures and humidity levels.
Performance Conditions Test Cases
Performance tests ensure the elevator’s efficiency and speed under various scenarios.
- Verify that the elevator reaches different floors within the specified time frame.
- Verify that the doors open and close swiftly without jerking movements.
- Verify that the elevator accelerates and decelerates smoothly to provide a comfortable ride.
- Verify that the elevator adjusts its speed based on the distance between floors to optimize travel time.
- Verify that the elevator maintains consistent speed even during sudden starts and stops.
User Interface Conditions Test Cases
User interface tests focus on the visual and interactive elements of the elevator.
- Verify that the floor display is visible in varying lighting conditions and from different angles.
- Verify that the button layout is intuitive, preventing accidental selections.
- Verify that the emergency communication system provides clear audio and visual signals.
- Verify that the touch screen, if present, responds accurately to touch gestures.
- Verify that the elevator provides visual and auditory warnings for door movements, ensuring passenger safety.
Safety Conditions Test Cases
Safety tests are crucial to prevent accidents and ensure passenger well-being.
- Verify that the emergency brake halts the elevator immediately without jolting passengers.
- Verify that sensors detect obstructions and prevent doors from closing on objects or passengers.
- Verify that the elevator has fire safety protocols, such as automatic shutdown and safe floor evacuation procedures.
- Verify that the elevator has a backup power source to facilitate safe evacuation during power failures.
- Verify that the elevator complies with all safety regulations and standards applicable in the region.
Positive Test Cases For Elevator
Positive test cases validate expected behavior under normal circumstances.
- Verify that the elevator travels smoothly from one floor to another without delays.
- Verify that the elevator responds promptly to user commands, indicating a seamless user experience.
- Verify that the elevator efficiently handles multiple simultaneous requests without errors.
- Verify that the elevator provides accurate and clear announcements for each floor, aiding passengers.
- Verify that the elevator resumes normal operation after minor disturbances, such as temporary power fluctuations.
Negative Test Cases For Elevator
Negative test cases evaluate the elevator’s response to unexpected or erroneous inputs.
- Verify that the elevator detects and handles a jammed door, preventing further attempts to close.
- Verify that the elevator safely stops and activates emergency lights in case of a sudden power outage during operation.
- Verify that the elevator does not respond to invalid or conflicting user commands, preventing confusion.
- Verify that the elevator stops all movements if sensors detect an obstruction in the door’s path.
- Verify that the elevator displays clear error messages for passengers and maintenance staff in case of malfunctions.
A meticulous testing process is indispensable to ensure elevators function reliably, providing a safe and efficient mode of vertical transportation.
By adhering to these comprehensive test cases, elevator manufacturers can guarantee a seamless and secure mobility experience for all users. Regular testing, coupled with adherence to safety standards, is paramount to sustaining elevators as essential and trustworthy components of our daily lives.
