Validating Role Name Parsing and App ID Extraction in Apollo Config

A comprehensive test suite for Apollo’s RoleUtils class that validates role name parsing and app ID extraction functionality. The tests ensure proper handling of various role name formats and patterns used in the Apollo configuration system.

Test Coverage Overview

The test suite provides thorough coverage of the RoleUtils class functionality, focusing on app ID extraction from different role name formats.

Tests master role name parsing with various patterns
Validates app ID extraction from general role names
Covers edge cases including null returns and multiple segments
Verifies handling of different role prefixes (Master, ModifyNamespace, ReleaseNamespace)

Implementation Analysis

The implementation uses JUnit 4 framework with a clear and concise testing approach. Each test method focuses on a specific aspect of role name parsing.

The testing pattern follows AAA (Arrange-Act-Assert) with multiple assertions per test method to validate different scenarios efficiently. The tests utilize assertEquals and assertNull methods for verification.

Technical Details

Testing Framework: JUnit 4
Test Methods: @Test annotation based
Assertion Methods: assertEquals, assertNull
Test Class Structure: Public class with independent test methods
Error Handling: Exception declarations in method signatures

Best Practices Demonstrated

The test suite exemplifies several testing best practices including clear method naming, focused test scenarios, and comprehensive assertion coverage.

Descriptive test method names that indicate functionality being tested
Multiple assertions to cover different scenarios within related contexts
Proper test isolation and independence
Clear and consistent test structure
