Обсуждение: TESTING the DATABASE
Hello to all, Is there anyone who can explain me briefly, how can I test the database that I created using PostgreSQL? Thanks a lot for the time you spent ... -- ::::::::::::::::::::::::::::::::::::::::::::::::: Research Assistant Himmet KARAMAN Istanbul Technical University Geodesy and Photogrammetry Eng.

Well, at a basic level...
$ psql mydbname
Welcome to psql 7.3.2, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit
mydbname=> create table mytable ( a integer );
mydbname=> insert into mytable (a) values (1);
mydbname=> select * from mytable;
a
---
1
(1 row)
mydbname=>\q
The question is, what is it you want to test?

Hi,
I want to test all part of the database.
If the relations work, and all of the tables are ok, and can i make queries on my database...
i mean can my database do everything wright?
Is there any tool or command to test it?
Thanks again

Compile from source and do a make check. That does this kind of regression testing..Refer to build instructions in postgresql sources..

You can easily write a script to construct a script which will issue queries against all your tables individually , but then you're querying the database in order to get that list of tables. With more effort you could write a script to determine all the foriegn keys and construct many queries to test the joining of tables based on this information, but again you'll be querying the database in order to get that information in the first place. In short, I don't believe there can be a tool that does what you want. If just checking referential integrity and queriability (I don't think that is a word btw) is what you want then it is possible to do it if you feel you can rely on the system tables working as they should. Having said that. Take a look in the source at src/test/regress/... as that could provide you with a useful framework for you to incorporate the knowledge of correctness that an automatic tool can not provide. -- Nigel J.

If you want to test your own schema to make sure it works (i.e. foreign key relations work right, etc...) You'll have to write your own SQL to prove it. If you want to test your postgresql installation to make sure it's stable and reliable under load, there are several different benchmarks out there that can help. pgbench comes with postgresql, and is in the $SRC/contrib/pgbench directory. Just cd there as root and do a 'make install' to install it, then run it as a normal postgresql user to see it's options. Look for the OSDB test suite on google, it's much larger and more stressing on the system than pgbench tends to be, and is meant to be a more well rounded benchmarking suite. Finally, there's a nearly finished TPC-C style benchmark on sourceforge: http://sourceforge.net/cvs/?group_id=52479 which was reported here on the list a few days ago. No idea how close to finished it is, but it's probably worth a look.
