Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integration testing of web services is complex and costly due to the need for deep understanding of internal functionality, making existing black-box testing methodologies inefficient.
Innovation Solution
A method that automatically generates and tests web service test cases based on metadata, using heuristic algorithms and stochastic processes to select test parameters, and evaluates learning data to adaptively generate new test cases, thereby reducing the complexity and cost of integration testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional integration testing methods are used for web services, then comprehensive code coverage can be achieved, but the complexity and cost of testing increases significantly due to the need for deep understanding of internal functionality
Solution Approach 1:
The system enables self-service testing by automatically generating test cases from web service metadata without requiring test developers to understand internal functionality. The web service itself provides the necessary information through its metadata, making the testing process independent of human expertise in the service's internal workings.
Solution Approach 2:
The invention extracts essential testing information directly from the web service metadata, separating the test case generation process from the need to understand internal service logic. By taking out only the necessary metadata elements (operations, parameters, data types), the system creates test cases without requiring deep internal knowledge.
2Reliability
If traditional integration testing methods are used for web services, then thorough testing can be performed, but the time and resources required increase significantly
Solution Approach 1:
The system performs preliminary action by automatically generating test cases from web service metadata before actual testing begins. This pre-generation process eliminates the time-consuming manual analysis and creation phases, allowing testing to start immediately with comprehensive test coverage already prepared.
Solution Approach 2:
The invention replaces the mechanical process of manual test case creation with an automated system that uses metadata-driven generation. This substitution eliminates the need for human test developers to manually analyze and create test cases, significantly reducing testing time while maintaining thoroughness.
3Adaptability or versatility
If manual test case development is used for web services, then test cases can be customized, but the cost and effort of development increase
Solution Approach 1:
The system achieves universality by creating a metadata-driven test case generation framework that works across different web services without requiring service-specific customization. The same automated process can generate test cases for any web service that provides metadata, eliminating the need for manual customization while maintaining adaptability to different service types.
Data Source
AI summary
A method of testing a web service includes obtaining web service metadata from the web service. Test cases are generated automatically using the web service metadata, heuristic algorithm modules selected based on the contents of the web service metadata, and stochastic processes. Energy selection logic is used to update test parameters included in the test cases between rounds of testing until a set of test cases is generated that produces test results meeting one or more predetermined criteria. Testing is performed periodically using that set of test cases until the test results indicate that the web service has changed. New test cases are automatically generated and used to test the web service until test results meet the one or more predetermined criteria.
