Testing Investment Controller Integration in Maybe Finance

This test suite validates the investments controller functionality in the Maybe Finance application, focusing on investment account management and integration with accountable resources. It establishes authentication and account setup for testing investment-related operations.

Test Coverage Overview

The test suite covers investment controller operations with a focus on account management and authentication workflows.

Key areas tested include:

User authentication and session management
Investment account access and setup
Integration with AccountableResourceInterfaceTest module
Family admin user permissions and account relationships

Implementation Analysis

The testing approach utilizes Rails’ ActionDispatch::IntegrationTest framework for comprehensive controller testing. The implementation employs module inclusion for shared accountable resource testing patterns, demonstrating modular test design.

The setup method establishes the test environment by authenticating a family admin user and configuring an investment account fixture, enabling consistent test state management.

Technical Details

Testing components include:

ActionDispatch::IntegrationTest framework
Custom AccountableResourceInterfaceTest module
Rails test fixtures for user and account data
Authentication helpers (sign_in method)
Test setup configuration for consistent state

Best Practices Demonstrated

The test implementation showcases several testing best practices in Rails applications.

Notable practices include:

Modular test design through interface module inclusion
Proper test setup and state management
Use of fixtures for test data consistency
Clear separation of authentication and resource testing
Focused test scope for investment-specific functionality
