Testing and Quality Assurance

Testing Levels

• Unit Testing:
  Test individual components (e.g., webcam capture, hand detection, and CNN prediction).

• Integration Testing:
  Ensure smooth communication between modules (data acquisition, classification, and output).

• System Testing:
  Validate the complete system in a controlled environment, checking for latency and accuracy.

• User Acceptance Testing (UAT):
  Gather feedback from end users to confirm that the system meets usability and performance expectations.

Sample Test Cases

1. Application Launch: Verify that the application starts and initializes the webcam.
2. Gesture Recognition: Confirm that specific hand gestures are accurately classified.
3. Text-to-Speech: Check that the TTS engine correctly synthesizes speech for the recognized text.
4. Clear Functionality: Ensure that the clear button resets the input field.
5. Suggestion Mechanism: Validate that word suggestions are provided for incomplete inputs.
