Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software testing systems face challenges in regression testing, particularly for complex network services like reverse proxy services, due to labor-intensive test case creation, lack of documentation, and the need for continuous updates to keep pace with changing service behaviors.
Innovation Solution
An adaptive testing service (ATS) that automatically generates and deprecates test cases based on observed behaviors of network services, using telemetry data and machine learning algorithms to identify classes of behaviors, strip environment-specific variables, and generate environment-specific test cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual test case creation is performed to cover new service behaviors, then test case coverage is improved, but labor intensity and error rate increase significantly
Solution Approach 1:
The system automatically generates test cases by observing service behaviors in production environments and analyzing telemetry data, eliminating the need for manual test case creation. The service monitors itself and autonomously creates test cases that reflect actual service behaviors, thereby improving coverage while reducing labor intensity.
Solution Approach 2:
The system continuously collects telemetry data from production environments, analyzes observed behaviors, and uses this feedback to automatically generate and update test cases. This closed-loop feedback mechanism ensures test cases remain synchronized with actual service behaviors without manual intervention.
2Reliability
If test cases are manually updated continuously to keep pace with service behavior changes, then test case relevance is improved, but time consumption and maintenance effort increase
Solution Approach 1:
The system continuously monitors service behaviors in production environments and automatically updates test cases in real-time or near-real-time. This continuous operation ensures test cases remain relevant to current service behaviors without requiring periodic manual updates, thereby reducing maintenance time while maintaining high relevance.
Solution Approach 2:
The system autonomously detects service behavior changes through telemetry data analysis and automatically generates updated test cases without human intervention. This self-updating capability eliminates the time-consuming manual maintenance process while ensuring test cases continuously reflect current service behaviors.
3Reliability
If comprehensive test cases are created for all possible service behaviors, then test coverage is improved, but system complexity and test case management difficulty increase
Solution Approach 1:
The system segments test case generation into distinct modules: telemetry data collection, behavior analysis, test case generation, and execution. Each module handles a specific aspect of the testing process independently, reducing overall system complexity while maintaining comprehensive coverage through coordinated operation of these segmented components.
Solution Approach 2:
The system creates a universal test case generation framework that can handle multiple service behaviors, environments, and test types through a single automated process. This multi-functional approach eliminates the need for separate manual test case creation processes for different scenarios, reducing management complexity while maintaining comprehensive coverage.
4Measurement precision
If testing is performed across multiple execution environments with different requirements, then service behavior accuracy is improved, but testing complexity and resource requirements increase
Solution Approach 1:
The system implements a universal test case generation framework that automatically adapts to multiple execution environments by analyzing telemetry data from each environment and generating environment-specific test cases through a single centralized process. This approach maintains high measurement precision across environments while reducing testing complexity by eliminating the need for separate manual test case creation for each environment.

AI summary
Techniques are disclosed to implement an adaptive testing service (ATS) capable of automatically generating test cases for a network service to adapt test coverage to observed behaviors of the network service. In embodiments, the ATS uses telemetry data from a production version of the network service to identify classes of testable behaviors. Test cases are generated for the behaviors and assigned weights based on frequency or recency metrics of the behaviors. The test cases are stored in a test case repository, and may be used to monitor the production version of the network service or verify code changes to a development version of the network service. The test case weights may be used to select which test cases to run or determine whether code changes should be accepted or rejected. The test cases are evolved over time to adapt to behavior changes in the network service.
