Validating AppNamespace Repository Operations in Apollo Config

This test suite validates the AppNamespace repository functionality in Apollo Configuration Service, focusing on namespace visibility and retrieval operations. The tests ensure proper handling of public and private namespaces in the Apollo configuration system.

Test Coverage Overview

The test suite provides coverage for AppNamespace repository operations with specific focus on public namespace retrieval.

Tests findByNameAndIsPublicTrue method for existing public namespaces
Verifies behavior when querying non-existent public namespaces
Validates correct AppId association with namespaces

Implementation Analysis

The testing approach utilizes JUnit framework with Spring integration testing capabilities.

Key patterns include:

Dependency injection of repository components
Extension of AbstractIntegrationTest for setup
Assertion-based verification of repository responses

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
Spring Test context for dependency injection
Repository layer integration testing
Assert utilities for result validation

Best Practices Demonstrated

The test suite exemplifies several testing best practices in repository layer validation.

Isolated test methods for specific functionality
Clear test method naming conventions
Proper exception handling expectations
Integration test base class extension
