TAP test

A TAP test is a regression test which uses the Perl TAP tools, which provide more flexible possibilities for testing than the SQL-based regression tests.

TAP tests and the associated infrastructure were first added in PostgreSQL 9.4.

Prerequisites

• PostgreSQL must have been compiled with the --enable-tap-tests option
• the Perl module IPC::Run must be present (this is widely available and often installed by default)

Change history

• PostgreSQL 15
  • PostgresNode and TestLib Perl modules moved to custom namespace PostgreSQL::Test (b3b4d8e6)
• PostgreSQL 12
  • option TAP_TESTS added for automatically enabling TAP tests in extensions (commit d3c09b9b)
• PostgreSQL 9.4
  • added (commit 7d0f493f)
