pg_partman Test Suite
The pgTAP testing suite is used to provide an extensive and easily maintainable set of unit tests. Please see the pgTAP home page for more details on its installation and use.
Tests assume that the required extensions have been installed in the following schemas:
pg_partman: partman pgTAP: public
If you've installed any of the above extensions in a different schema and would like to run the test suite, simply change the configuration option found at the top of each testing file to match your setup. If you've also installed pg_jobmon, be aware that the logging of the tests cannot be rolled back and any failures will be picked up by the monitoring in the jobmon extension.
SELECT set_config('search_path','partman, public',false);
Once that's done, it's best to use the pg_prove script that pgTAP comes with to run all the tests. I like using the -o -f -v options to get more useful feedback.
pg_prove -ovf /path/to/partman/test/*.sql
The tests must be run by a superuser or a user with complete create/write access to the database since roles & schemas are created & dropped as part of the test. There is a separate test script for each of the partitioning types. The tests are not required to run pg_partman, so if you don't feel safe doing this you don't need to run the tests. But if you are running into problems and report any issues without a clear explanation of what is wrong, I will ask that you run the test suite so you can try and narrow down where the problem may be. You are free to look through to tests to see exactly what they're doing. All tests in the top level of the test folder are run inside a transaction that is rolled back, so they should not change anything (except jobmon logging as mentioned).
Tests for the time-custom partition type are in their own folder. The 30second test frequently errors out if run in certain 30 second blocks. Waiting for the next 30 second block and running it again should allow it to pass.
Tests for the reindexing script can be found in the test/test_reindex folder. These tests cannot just be run all at once and are not run within rolled back transactions. They must be run in order, one at a time, and there are explicit instructions at the end of each test for what to do next.
Tests for the Background Worker can be found in the test/test_bgw folder. Please read the header comments at the top of each test for the postgresql.conf settings required for that test.
Partitioning in PostgreSQL 10
pgtap currently does not have any tests for natively partitioned tables. The below two functions should be installed to the same schema as pgtap to allow the native partitioning tests to work. Once pgtap adds this support in itself, this will no longer be needed
create or replace function has_partition(name, name, text) returns text language sql as $$ SELECT ok(_rexists('p', $1, $2), $3); $$;
create or replace function hasnt_partition(name, name, text) returns text language sql as $$ SELECT ok( NOT _rexists('p', $1, $2), $3); $$;
