PostgreSQL testing frameworks

PostgreSQL testing frameworks allow developers to process automated tests for existing stored procedures with unit tests and Test-Driven Development (TDD). Because all test cases are saved in our PostgreSQL databases, they will not be stored by files, version control utilities, or external resources. One test case is a group of many database tests, and each test case is executed independently. After a test case has been executed, the changes that it has made are automatically rolled back.

There are four famous test frameworks for PostgreSQL, as follows: 

• pgTap: This is a unit test framework for PostgreSQL.
• PGUnit: This is a simpler testing tool than pgTap.
• Simple pgunit: This offers another approach for unit tests.
• Testgres: This is a Python testing framework for PostgreSQL.

These testing frameworks allow users to really verify the structure of their database schema, to exercise any views, procedures, functions, rules, or triggers. Furthermore, the testgres Python tool can also start a replica for a PostgreSQL database and even execute performance benchmarks for the database.
