Through the different topics that we will develop here, we will be applying different techniques to carry out tests. We are going to start with one of the most used techniques in production environments: pgTAP, which has several functions for use case tests and also provides the output in TAP. The Test Anything Protocol (TAP) is well known for being suitable for harvesting, analysis, and reporting with a TAP harness.
The official website of pgTAP is https://pgtap.org/.
