Microservice HTTP Error Simulation for Resiliency Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional systems for testing application resiliency, or chaos testing, involve breaking system components, leading to system downtime and lack the ability to selectively simulate specific HTTP error response codes, making it difficult to understand how microservices handle these codes.
Innovation Solution
A system and method for testing application resiliency that uses a graphical user interface to select and simulate HTTP error response codes between microservices, allowing monitoring of responses without actual downtime, using APIs to transmit these codes and generate graphical representations of the results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional chaos testing breaks system components to test resiliency, then the system can detect how components handle failures, but it causes system downtime and lacks selectivity for specific error codes
Solution Approach 1:
The patent creates simulated HTTP error responses that replicate real error conditions without actually breaking system components. Instead of terminating microservices or causing real failures, the system injects simulated error codes (4xx, 5xx) into the microservice communication stream, allowing resiliency testing while maintaining system availability and avoiding downtime.
Solution Approach 2:
The patent introduces an intermediary component that sits between microservices and intercepts/injects simulated HTTP error responses. This intermediary allows controlled injection of error conditions into specific microservice calls without affecting the actual microservice instances, enabling selective testing of error handling while preventing system downtime.
2Reliability
If traditional chaos testing breaks system components, then failure scenarios can be detected, but it lacks the ability to selectively simulate specific HTTP error response codes
Solution Approach 1:
The patent applies local quality by enabling selective injection of specific HTTP error codes (4xx client errors, 5xx server errors) into specific microservice communications. The system can target particular microservices and inject particular error codes based on testing requirements, rather than applying uniform failure scenarios across the entire system. This allows precise testing of how specific microservices handle specific error conditions.
Solution Approach 2:
The patent implements dynamics by making the error injection process configurable and adaptable. The system can dynamically select which HTTP error codes to inject, which microservices to target, and when to perform testing based on operational requirements. This dynamic approach enables versatile testing scenarios tailored to specific resiliency concerns.
3Adaptability or versatility
If simulated HTTP error codes are transmitted between microservices, then customized resiliency testing is enabled, but system complexity increases
Solution Approach 1:
The patent achieves universality by designing a testing system that can handle multiple HTTP error code types (4xx, 5xx), target multiple microservices, and support various testing scenarios through a single unified platform. The system provides a comprehensive suite of resiliency testing capabilities including different error codes, multiple service targets, and configurable testing parameters, all accessible through one multi-functional testing infrastructure.
Data Source
AI summary
Disclosed embodiments may include a system for testing application resiliency. The system may receive first data associated with a plurality of microservices within a microservice architecture. The system may generate a graphical user interface (GUI) configured to display the first data and an icon associated with each of the plurality of microservices. The system may receive, via the GUI, a selection of the icon associated with a first microservice of the plurality of microservices. The system may transmit a call via an Application Programming Interface (API), from the first microservice to further microservice(s) of the plurality of microservices. The system may receive, via the GUI, a request to transmit a simulated Hypertext Transfer Protocol (HTTP) error response code from the further microservice(s) to the first microservice, transmit the simulated HTTP error response code from the further microservice(s) to the first microservice, and monitor a response from the first microservice.
