## What it is
pgTAP is a unit testing framework for PostgreSQL written in PL/pgSQL and PL/SQL. It provides a comprehensive set of TAP-emitting assertion functions for testing schemas, functions, triggers, and query results, and integrates with TAP harnesses or xUnit-style testing.

## Use cases
- unit test postgresql database functions
- verify database schema structure in tests
- test triggers and views in postgres
- run TAP-emitting database tests with a harness
- write xUnit-style tests inside postgres
- assert query results match expected sets

## When to choose
- you develop PostgreSQL-backed applications and want to test the database itself
- you want TAP output compatible with existing test harnesses
- you need assertions for schema objects, functions, triggers, and result sets

## When to avoid
- you use a database other than PostgreSQL
- you cannot install extensions on the database server host
- you only need application-level tests that happen to touch the database

## Facets
- artifact type: library
- maturity: active
- function: testing
- domain: databases, testing, developer-tools
- platform: windows, cli
- tags: postgresql, tap, unit-testing, plpgsql, database-testing, xunit, linux, macos
