Testing Posts Controller CRUD Operations in brakeman

This test suite implements comprehensive functional testing for the Posts controller in a Rails application with XSS plugin integration. It validates core CRUD operations and ensures proper request handling and response management for the posts resource.

Test Coverage Overview

The test suite provides complete coverage of PostsController actions including index, create, read, update and delete operations.

Key functionality tested includes:

Post listing and retrieval
Post creation with proper redirect handling
Individual post viewing and editing
Post update validation
Deletion with database count verification

Implementation Analysis

The testing approach follows Rails controller testing conventions using ActionController::TestCase. It employs assertion-based testing patterns with specific focus on response status validation and model assignment verification.

Framework-specific features utilized include:

assert_difference for database change tracking
assigns(:posts) for instance variable checking
Rails routing assertions

Technical Details

Testing tools and configuration:

Minitest as the testing framework
ActionController::TestCase for controller specific testing
Rails fixtures for test data management
Built-in Rails assertion methods
Integration with XSS plugin security features

Best Practices Demonstrated

The test suite exemplifies Rails testing best practices through isolated controller tests, proper setup of test scenarios, and comprehensive validation of outcomes.

Notable practices include:

Systematic CRUD operation verification
Response status validation
Database state verification
Redirect path checking
Clear test naming conventions
