PostgreSQL tests

================

This directory contains a variety of test infrastructure as well as some of the

tests in PostgreSQL. Not all tests are here -- in particular, there are more in

individual contrib/ modules and in src/bin.

Not all these tests get run by "make check". Check src/test/Makefile to see

which tests get run automatically.

"make check"

isolation/

locale/

Sanity checks for locale data, encodings, etc

mb/

Tests for multibyte encoding (UTF-8) support

modules/

Extensions used only or mainly for test purposes, generally not suitable

for installing in production databases

perl/

Infrastructure for Perl-based TAP tests

regress/

PostgreSQL's main regression test suite, pg_regress

Test extensions and libraries

=============================

src/test/modules contains PostgreSQL extensions that are primarily or entirely

intended for testing PostgreSQL and/or to serve as example code. The extensions

here aren't intended to be installed in a production server and aren't suitable

for "real work".

Most extensions have their own pg_regress tests or isolationtester specs. Some

are also used by tests elsewhere in the tree.

If you're adding new hooks or other functionality exposed as C-level API this

is where to add the tests for it.
