SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive toolkit for writing reliable integration tests for PostgreSQL databases, ensuring data integrity, security, and correct application behavior.

Core Features & Use Cases

  • RLS Policy Testing: Verify Row-Level Security policies to ensure proper data access control for different user roles.
  • Test Data Seeding: Load fixtures efficiently using JSON, SQL, or CSV files.
  • Exception Handling: Gracefully manage and test expected database errors and transaction rollbacks.
  • Snapshot Testing: Create deterministic assertions by pruning dynamic values like IDs and dates.
  • Use Case: You need to ensure that only authenticated users can access and modify their own records in a multi-tenant application. This Skill allows you to write tests that simulate various user roles and verify that RLS policies correctly enforce data isolation.

Quick Start

Use the pgsql-test skill to set up database connections and run your PostgreSQL integration tests.

FAQPage Schema
How do I test PostgreSQL Row-Level Security policies for different user roles?▼

PostgreSQL RLS policy testing verifies data access control by simulating various user roles to ensure proper data isolation. This approach allows you to write integration tests that confirm authenticated users can only access and modify their own records in multi-tenant applications.

What is the best way to seed test data for PostgreSQL integration tests?▼

Seeding test data for PostgreSQL integration tests is best handled by loading fixtures efficiently using JSON, SQL, or CSV files. This method provides structured input for your test suites, ensuring reliable and reproducible database states before executing assertions.

How does snapshot testing handle dynamic values like IDs and dates in database tests?▼

Snapshot testing handles dynamic values by pruning generated IDs and dates to create deterministic assertions. By stripping non-deterministic data during integration tests, it ensures your database state comparisons remain stable across multiple test runs.

Can I test database transaction rollbacks and exception handling in PostgreSQL?▼

You can test database transaction rollbacks and exception handling in PostgreSQL by managing transaction isolation within your tests. This technique gracefully manages expected database errors and verifies that transaction rollbacks function correctly to maintain data integrity.
