Description

Enhancement request

TAP, the Test Anything Protocol, is a simple text-based interface between testing modules in a test harness. It decouples the reporting of errors from the presentation of the reports. pgTAP is a unit testing framework for PostgreSQL written in PL/pgSQL and PL/SQL. It includes a comprehensive collection of TAP-emitting assertion functions, as well as the ability to integrate with other TAP-emitting test frameworks.

Maybe we can support the tap ut framework for TiDB and just use sql as code in tidb ut.

Contributor guide

Research direction
Explore TAP protocol and pgTAP implementation, then design a similar test framework for TiDB using Go and SQL. Adapt assertion functions to work with TiDB's SQL dialect and integrate with existing test harness.
