Supabase Test Helpers

A collection of functions designed to make testing Supabase projects easier. Created as part of our open source SaaS starter for Supabase.

Quick Start

If you're using Supabase:

  1. Install dbdev following the instructions here: github.com/supabase/dbdev
  2. Install the test helpers as an extension:
select dbdev.install('basejump-supabase_test_helpers');

I don't recommend activating the extension in production directly, instead you can activate it as part of your test suite. For example:

BEGIN;
CREATE EXTENSION "basejump-supabase_test_helpers";

select plan(1);
-- create a table, which will have RLS disabled by default
CREATE TABLE public.tb1 (id int, data text);
ALTER TABLE public.tb1 ENABLE ROW LEVEL SECURITY;

-- test to make sure RLS check works
select check_test(tests.rls_enabled('public', 'tb1'), true);

SELECT * FROM finish();
ROLLBACK;

For a basic example, check out the example blog tests.

Manual Installation

Copy the contents of supabase_test_helpers.sql into the very first alphabetical test in your test suite, such as 00000-supabase_test_helpers.sql. This will ensure that the test helpers are removed after your tests have run.

Writing tests

Check out the docs below for available helpers. To view a comprehensive example, check out our blog tests.

Contributing

Yes, please! Anything you've found helpful for testing Supabase projects is welcome. To contribute:

  • Add pgTAP compliant test functions to supabase_test_helpers.sql
  • Comments should be added above each function, follow the examples in the file.
  • Add tests for your functions in tests/XX-your-function-name.sql
  • Submit a PR

Test Helpers

The following is auto-generated off of comments in the supabase_test_helpers.sql file. Any changes added to the README directly will be overwritten.
