Virtual Callback Object Generation for Load Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load testing methods require significant manual effort and resource-intensive simulation of real clients, making it challenging to efficiently test networked systems under increasing loads and complex scenarios, especially with the rise of interactive and asynchronous applications.
Innovation Solution
The system and method for creating virtual callback objects allow for the automation of load testing by filtering out internal client operations and generating virtual callback objects, which can be used to simulate client-server interactions with reduced resource consumption, enabling accurate and scalable load simulation without the need for manual programming of dummy callbacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real clients are used for load testing, then the accuracy of load simulation is improved, but the resource consumption and testing time increase significantly
Solution Approach 1:
The patent creates virtual callback objects that replicate the essential behavior of real client callback objects without requiring actual client processes to run. These virtual objects copy the necessary interface and behavior patterns, allowing load testing to simulate real user scenarios while consuming minimal system resources compared to running actual clients.
Solution Approach 2:
The virtual callback objects are lightweight, disposable entities that can be created and destroyed without significant resource overhead. They serve the purpose of load simulation temporarily and then can be discarded, eliminating the need to maintain complex client processes throughout the testing duration.
2Adaptability or versatility
If manual programming of dummy callbacks is performed, then the flexibility of load testing scenarios is improved, but the time and effort required for setup increases
Solution Approach 1:
The system automatically generates virtual callback objects by intercepting and analyzing actual client callback objects during runtime. The virtual objects are created self-service through the interception mechanism, eliminating the need for manual programming or configuration of dummy callbacks while maintaining scenario flexibility.
Solution Approach 2:
The virtual callback objects are generated in advance during the load testing setup phase by analyzing real client behavior patterns. This preliminary generation of virtual objects based on actual client scenarios allows for flexible test case creation without requiring manual programming during the testing execution.
3Productivity
If multiple concurrent virtual users are simulated, then the load testing capability is improved, but the system complexity increases
Solution Approach 1:
The patent segments the complex client-server communication into discrete virtual callback objects, each representing a specific client interaction pattern. This segmentation allows multiple concurrent virtual users to be simulated by managing individual virtual objects independently, reducing the overall system complexity compared to managing multiple real client processes.
Data Source
AI summary
A method for creating a virtual callback object using a client callback object. A client device executes a client application. A client callback object is used by the client application in a client/server transaction between a server device and the client device. A recorder module captures the client/server transaction between the client device and the server device, and the client callback object is used in the client/server transaction. Internal client operations may be filtered from the client callback object to create the virtual callback object. A script may be generated using the virtual callback object.
