Testing Router Configuration Adjustment Workflow in CAT

This test suite validates the router configuration adjustment functionality in the CAT monitoring system. It focuses on testing the RouterConfigAdjustor component’s ability to handle date-based configuration adjustments and ensures proper routing behavior.

Test Coverage Overview

The test suite provides coverage for the RouterConfigAdjustor component’s adjustment functionality.

Key areas tested include:

Date-based configuration adjustments
Period-specific router configuration updates
Component lookup and initialization
Date format parsing and handling

Implementation Analysis

The testing approach utilizes JUnit framework with ComponentTestCase as the base class for dependency injection and component lookup.

Technical implementation details:

Uses ComponentTestCase for IoC container management
Implements date parsing using SimpleDateFormat
Tests the Adjust method with specific timestamp inputs

Technical Details

Testing infrastructure includes:

JUnit testing framework
ComponentTestCase for dependency injection
SimpleDateFormat for date parsing
RouterConfigAdjustor component

Best Practices Demonstrated

The test exhibits several testing best practices:

Clear separation of concerns with focused test scope
Proper dependency injection usage
Explicit date formatting and parsing
Exception handling for date parsing
Component-based testing architecture
