Testing Multi-Tenant Search Isolation in Searchkick

This test suite validates multi-tenancy functionality in Searchkick using the Apartment gem for database isolation. It ensures proper data separation and search functionality across different tenants in a multi-tenant application environment.

Test Coverage Overview

The test suite covers essential multi-tenancy scenarios in Searchkick integration.

Key areas tested include:

Tenant isolation and data separation
Search functionality within specific tenant contexts
Product name indexing across different tenants
Proper tenant switching and state management

Implementation Analysis

The testing approach utilizes Minitest framework with Apartment gem integration for tenant management.

Testing patterns include:

Setup and teardown hooks for tenant management
Explicit tenant switching using Apartment::Tenant.switch!
Assertion-based validation of search results
Conditional test execution based on Apartment availability

Technical Details

Testing components and configuration:

Minitest as the testing framework
Apartment gem for multi-tenancy support
Searchkick integration for search functionality
Custom store_names helper method
assert_search for validation
Load: false option for performance optimization

Best Practices Demonstrated

The test suite demonstrates several testing best practices for multi-tenant applications.

Notable practices include:

Proper test isolation through setup/teardown
Graceful handling of optional dependencies
Clear test case organization
Explicit state management
Clean tenant reset after tests
