Multi-Node Automation Framework for Synchronized Test Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art automation frameworks offer limited test coverage for multi-node environments, failing to adequately simulate real-time environments, which can result in missed regression tests when applications are executed in the field.
Innovation Solution
An automation framework that runs on a multi-node environment with multiple host computers, utilizing a test controller to initialize and synchronize script execution across hosts, ensuring each host has its own script execution engine and logger for comprehensive testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-node automation framework is used, then the device complexity is low, but the test coverage is limited and cannot adequately simulate real-time multi-node environments
Solution Approach 1:
The automation framework is segmented into multiple independent host computers (first host, second host, third host, etc.), each capable of executing test scripts independently. This segmentation allows the framework to simulate multi-node environments while maintaining the reliability benefits of distributed testing, directly addressing the limited test coverage of single-node frameworks.
Solution Approach 2:
A synchronization component acts as an intermediary between multiple hosts to coordinate test execution and synchronize results. This mediator enables the complex multi-node testing capability while abstracting the complexity from the test scripts themselves, allowing hosts to execute scripts independently while still achieving coordinated test coverage.
2Reliability
If multiple host computers are used to expand test coverage, then the test coverage is improved, but the synchronization and coordination between hosts increases complexity
Solution Approach 1:
The synchronization component implements feedback mechanisms by collecting execution results from each host and using this information to coordinate subsequent test steps across hosts. This feedback loop enables automatic synchronization without requiring complex manual coordination, resolving the contradiction between expanded test coverage and synchronization complexity.
Solution Approach 2:
The framework copies the same test script to multiple hosts, allowing identical testing logic to execute in parallel across different nodes. This copying approach simplifies synchronization because the same script produces comparable results that can be easily correlated, reducing the complexity of coordinating between hosts while maximizing test coverage.
3Productivity
If each host executes its own script instructions independently, then the test execution speed is improved, but the coordination and result comparison between hosts becomes more complex
Solution Approach 1:
The synchronization component serves as an intermediary that collects results from independently executing hosts and performs automated comparison. This mediator handles the coordination complexity internally, allowing hosts to execute scripts in parallel at high speed while the synchronization layer manages the complexity of result correlation and coordination.

AI summary
An automation framework for a multi-node environment is described. A first host computer executes a parser, a first execution engine, a first communication component, and a first logger. A second host computer executes a second execution engine, a second communication component, and a second logger. The parser parses a test case suite to identify multiple script instructions to test an application. The first execution engine executes the first script instruction to locally execute the first script instruction. The first communication component communicates an execution request to the second communication component to remotely execute the first script instruction. The second communication component instructs the second execution engine to execute the first script instruction. The first and the second logger log a first and a second result of executing the first script instruction on the first and the second host computer. The first logger outputs the first result and/or the second result.
