pgTAP installation

Hi all,

I'm just tipping my toe into the water with pgTAP for the first time, 
and must be doing something wrong - I can't seem to get it working.

I'm on Kubuntu Hirsute, and I've installed both PostgreSQL 13 and pgTAP 
from apt.postgresql.org:

    sudo apt install postgresql-13
    sudo apt install postgresql-13-pgtap

Then I connected to my database and installed pgTAP there:

     create extension pgtap;

And I can see it there:

gfc_booking6_dev=# \dx
                  List of installed extensions
   Name   | Version |   Schema   |         Description
---------+---------+------------+------------------------------
  pgtap   | 1.1.0   | public     | Unit testing for PostgreSQL
  plpgsql | 1.0     | pg_catalog | PL/pgSQL procedural language
(2 rows)


However, when I try to use it, I get:

gfc_booking6_dev=# select * from noplan();
ERROR:  function noplan() does not exist
LINE 1: select * from noplan();
                       ^
HINT:  No function matches the given name and argument types. You might 
need to add explicit type casts.

Am I missing a step somewhere?

Many thanks in advance,

Ray.

I think you need to load the script to make use of the functions.
where it says
-- Load the TAP functions.

ignore,
I was wrong.
the script gets loaded by enabling the extension.

postgres@db:~/postgresql-14beta1/contrib/pgtap$ dropdb test
postgres@db:~/postgresql-14beta1/contrib/pgtap$
postgres@db:~/postgresql-14beta1/contrib/pgtap$ createdb test
postgres@db:~/postgresql-14beta1/contrib/pgtap$ psql test
psql (14beta1)
Type "help" for help.

test=# create extension pgtap;
CREATE EXTENSION
test=# SELECT * FROM no_plan();
 no_plan

This was a wrong suggestion. sorry.
i'll try to reproduce what resulted in functions not getting loaded in your case.

ok i guess you have a typo there. the function name is no_plan(), but you called noplan() 

tt=# select * from noplan();
ERROR:  function noplan() does not exist
LINE 1: select * from noplan();
                      ^

Aaaargh - you're right, that's what the problem was. Thanks very much, 
and sorry for the noise.

Ray.
