Centralized Test Harness for Distributed System Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test techniques for distributed systems are inefficient as they require creating new test code for each component and struggle with coordinating multiple test codes, making it difficult to verify functional correctness and performance across the distributed environment.
Innovation Solution
A central system, or master system, is introduced to manage, track, and analyze tests across remote test systems by assigning unique identifiers to each test or group of tests, allowing for efficient tracking and coordination of tests executed in a distributed test environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized test code is inserted into production code for each component, then functional correctness can be verified, but test code creation becomes inefficient and coordination between test codes becomes extremely difficult
Solution Approach 1:
The patent introduces a test harness as an intermediary layer between the production code components and the testing process. This test harness manages test coordination centrally, eliminating the need for direct integration of specialized test code into production code for each component. The harness handles test case management, execution coordination, and result aggregation, thereby improving productivity while maintaining reliability verification.
2Reliability
If specialized test code is inserted into production code for each component, then functional correctness can be verified, but the complexity of coordinating multiple test codes increases significantly
Solution Approach 1:
The test harness serves as a central coordinator that mediates between multiple test codes and production components. It provides a unified interface for managing test executions across distributed components, handling coordination logic centrally rather than requiring complex interconnections between individual test codes. This reduces coordination complexity while maintaining comprehensive functional verification.
Solution Approach 2:
The test harness is designed as a universal testing framework that can manage multiple types of test codes and components through a single coordinated system. It provides multi-functional capabilities including test case management, execution scheduling, result collection, and defect tracking, thereby reducing the overall complexity of coordinating multiple test codes across different components.
3Reliability
If new test code is created for each new component, then comprehensive testing is achieved, but the time required for testing increases significantly
Solution Approach 1:
The test harness performs preliminary setup and configuration work before individual component testing begins. It pre-defines test cases, establishes test environments, and prepares coordination mechanisms in advance. This preliminary action eliminates repetitive setup tasks for each new component, allowing comprehensive testing coverage to be achieved more quickly by leveraging pre-configured test frameworks and reusable test assets.
Data Source
AI summary
In an embodiment, a method is provided for tracking a test. In this method, a test session identifier is transmitted to a test system. The test session identifier identifies a particular test session. A test of a component is triggered at the test system, and this test provides test results, which are received from the test system. The test results include the test session identifier, which allows the tests to be associated with the particular test session.
