HCI Test Driver Command File Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional software testing methods require separate test drivers for each component, which are not reusable, time-consuming, and prone to errors, especially in complex systems like ship-board combat platforms, where extensive verification of software components is necessary to handle various input combinations and ensure robust execution.
Innovation Solution
A system and method using a command file and HCI Test Driver to mimic user and external subsystem inputs, allowing for comprehensive testing and verification of software components without the need for separate simulators, enabling the reuse of test drivers across different components and developers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate test drivers are used for each software component, then each component can be tested independently, but the testing process becomes time-consuming and error-prone
Solution Approach 1:
The patent creates a universal test driver framework that can test multiple different software components through a standardized interface. The test driver uses command files with standardized commands (e.g., CREATE_WINDOW, PUSH_BUTTON, CHECK_RESULT) that can be applied across different GUI components, making the testing mechanism reusable and transferable between developers and components rather than requiring separate custom test drivers for each component
2Reliability
If comprehensive testing of all input combinations is performed manually, then software robustness can be verified, but the process becomes extensive and error-prone
Solution Approach 1:
The test driver automatically performs comprehensive testing by reading commands from command files and executing test sequences without requiring continuous manual intervention. The system automatically creates test windows, simulates user inputs, checks results, and generates reports, enabling the testing process to serve itself and reducing human error while maintaining thoroughness
3Adaptability or versatility
If custom test drivers are developed for each component, then specific testing requirements can be met, but the test drivers are not reusable or transferable
Solution Approach 1:
The test driver is segmented into distinct modular components: command file parsing, window creation, input simulation, result checking, and reporting. Each module handles a specific aspect of testing and can be independently configured through command files, allowing the system to adapt to different testing scenarios while maintaining reusability across components
4Reliability
If manual observation of test results is performed, then regression testing can be conducted, but the process requires extensive human effort and time
Solution Approach 1:
The test driver implements automated feedback mechanisms by comparing actual test results against expected results defined in command files. The system automatically generates test reports that indicate pass/fail status, highlighting discrepancies and providing detailed feedback on which tests succeeded or failed, eliminating the need for manual observation and enabling rapid regression testing
Data Source
AI summary
A method and a system for driving a computer interface for a user is provided. The system includes an interface client having a computer platform, a test driver having software on the computer platform; a window displayed to the interface client, the window providing an interface between the computer platform and the user; and a command file that provides an instruction to the computer interface for executing by the driver software, such that the instruction mimics a user input. The method includes providing instructions through a command file having an instruction for execution on the computer interface, providing driver software to the computer interface, and executing the instruction on the computer interface using the driver software, such that the instruction mimics a user input.
