1# Test2 3## Test Case Document: File Size vs. Resolution Management System4 5**1. Introduction**6 7This document outlines the test cases for the File Size vs. Resolution Management System, covering functional, edge case, and performance scenarios.  Testing will encompass both UI and API interactions, ensuring compliance with GDPR and HIPAA regulations.8 9 10**2. Functional Test Cases (Positive & Negative)**11 12| Test Case ID | Description | Input Data | Expected Result | Actual Result | Pass/Fail | Notes |13|---|---|---|---|---|---|---|14| FT-001 | Upload a standard image (JPEG, PNG) | 2MB image, 1920x1080 resolution | Image uploaded successfully; system suggests optimal file size/resolution. |  |  | Verify file size and resolution after upload. |15| FT-002 | Upload a large image (JPEG, PNG) | 10MB image, 4000x3000 resolution | Image uploaded successfully; system suggests optimized file size/resolution; user can choose from presets or manual override. |  |  | Verify compression rate and resolution impact. |16| FT-003 | Upload an image exceeding maximum allowed size | 50MB image | Error message indicating file size exceeded limit.  |  |  | Verify error message accuracy and handling. |17| FT-004 | Upload an image with unsupported format | .gif image | Error message indicating unsupported file format. |  |  | Verify error message accuracy and supported formats. |18| FT-005 | Select low resolution preset | 10MB image, choose "Low" resolution | Image resized and file size reduced significantly; preview matches expected resolution. |  |  | Compare file size before and after. |19| FT-006 | Select high resolution preset | 2MB image, choose "High" resolution (if applicable) |  Image resolution increased (if possible), file size increased accordingly. Preview matches expected resolution. |  |  | Verify resolution and file size changes. |20| FT-007 | Manual override of resolution | 5MB image, manually enter 800x600 resolution | Image resized to specified resolution; file size reduced. |  |  | Verify exact resolution and file size. |21| FT-008 |  Upload image with metadata (EXIF) | Image with location and timestamp metadata | Metadata handled according to GDPR/HIPAA requirements;  System either removes sensitive metadata or anonymizes it appropriately. |  |  | Verify metadata handling through inspection and logs. |22| FT-009 | API upload of image | Use API endpoint to upload image | Image uploaded successfully, response includes optimal size/resolution data. |  |  | Verify API response codes and data. |23| FT-010 | API access control | Attempt API access without proper authorization | Access denied; appropriate error code returned. |  |  | Verify appropriate authentication and authorization mechanisms. |24 25 26**3.

Edge Case Scenarios**40 41* **Extremely large image:** An image exceeding the system's capacity limits.42* **Corrupted image file:** Attempting to upload a corrupted or malformed image.43* **Image with embedded malicious code:**  Testing for security vulnerabilities (e.g., injection attacks).44* **Zero-byte image:** Attempting to upload an empty image file.45* **Image with unusual aspect ratio:** Extremely wide or tall images.46* **Simultaneous uploads by multiple users:** Load testing to assess system performance under stress.47* **Network interruption during upload:** Testing resilience to interruptions.48* **Server failure during upload:** Testing system's recovery capabilities.49 50 51**5.

Expected Results & Assertions**104 105Each test case in section 2 includes an "Expected Result" column.  Assertions in automation scripts (Section 6) will verify that the actual results match the expected results.  Assertions will check:106 107* Successful image uploads108* File sizes and resolutions before and after optimization109* Error messages and error handling110*  API response codes and data111* UI elements (buttons, messages) visibility and correctness112 113 114**8. Acceptance Criteria**115 116* All functional test cases pass.117* All edge case scenarios are handled gracefully.118* System performance meets defined requirements (response times, throughput).119* System is compliant with GDPR and HIPAA regulations (verified through security audits and testing).120* User satisfaction score improvements are achieved as per the KPI goals.121* Average file size reduction goal is met.122 123 124**9. Test Data Preparation Notes**125 126Prepare a diverse set of test images:127 128* Various sizes (small, medium, large, extremely large)129* Different formats (JPEG, PNG, GIF, etc.)130* Images with and without sensitive metadata (for GDPR/HIPAA testing)131* Corrupted images132* Images with unusual aspect ratios133 134 135**10. Test Automation Strategy**136 137A phased approach will be used, starting with unit tests for core functions (image processing, file validation).  Then, integration tests will validate interactions between different system components.  Finally, end-to-end UI tests (using Selenium) will cover the complete user workflow.  API tests will be implemented using a testing framework like `pytest` with appropriate HTTP libraries (e.g., `requests`).  Continuous integration will be used to automate the test execution and reporting.  This comprehensive approach ensures robust test coverage and early detection of defects.  Setup instructions for local and staging test environments will be documented separately.  The automation scripts will be designed to be modular and reusable to support future expansion and maintenance.
