Summary

Runs every pgTAP file in supabase/tests on the local Postgres container from #4102, without the Supabase stack.

  • bun run db:test (new subcommand in scripts/local-db.ts): creates pgtap in the extensions schema, then runs each supabase/tests/*.sql file in name order with psql inside the container (ON_ERROR_STOP=1, like pg_prove). A file fails on any not ok, a missing or unmet plan, or a SQL error. It prints one line per file, the failing lines (not ok, # diagnostics, ERROR/DETAIL/HINT/CONTEXT), totals, and exits non-zero on any failure.
  • The test_local_db job runs it after the two db:provision steps. The job is renamed Local Postgres provision and pgTAP (no Supabase stack).
  • 28_channel_device_counts.sql and 88_test_apps_derived_counter_guard.sql now drain the channel_device_counts queue first (inside their transaction). It assumed the queue was empty, but seed.sql fills it and only a pg_cron tick between the seed and the tests empties it, so right after provisioning the processor calls returned 10 instead of 1 (88 passed only because it runs after the first tick).
  • The supabase test db step in test_backend_sql is unchanged: both run side by side until a follow-up removes the old one.
  • AGENTS.md: one line for db:test.

No pg_prove: the supabase/postgres image doesn't ship it, and psql plus the plan/ok/not ok check is all this needs.

Test plan

  • Unit tests: bunx vitest run tests/local-db.unit.test.ts (pass, not ok, unmet plan, missing plan, SQL error)
  • CI Local Postgres provision and pgTAP (no Supabase stack): 110/110 files, 1,484 ok (job)
  • supabase test db (Run backend SQL checks) still green, including 28, 46 and 88 (job)
  • A deliberately broken test turns the job red: ok(false) in 01_test_dumy.sql gave FAIL 01_test_dumy.sql: 1 not ok, exit 1 (job); reverted in the next commit
  • Manual: bun run db:up && bun run db:provision && bun run db:test

Screenshots

Not applicable (tooling only).

Summary by CodeRabbit

  • New Features
    • Added a local database test command that runs SQL tests and reports results for each test file, including failures and incomplete test runs.
    • Automated the database tests in the local Postgres workflow after database provisioning.
  • Bug Fixes
    • Improved reliability of channel device count tests by clearing pending messages before checking results; the cleanup is rolled back with the test.
  • Documentation
    • Added instructions for running local database tests against a provisioned local Postgres database.

Add `bun run db:test`: installs pgtap in the `db:up` container and runs every
supabase/tests/*.sql file in name order with psql inside the container
(ON_ERROR_STOP, like pg_prove). A file fails on any `not ok`, a missing or
unmet plan, or a SQL error; the command prints one line per file, the
failing lines, totals, and exits non-zero on any failure.

The test_local_db CI job runs it after provisioning. The `supabase test db`
step in test_backend_sql is unchanged.

Walkthrough

The local database CLI now installs pgTAP and runs sorted SQL test files from supabase/tests. It summarizes TAP results and returns failure when a test fails. The package script, CI workflow, local database instructions, and two channel-device-count tests were updated.

Changes: Local database pgTAP testing

Layer / File(s) Summary
Capture and summarize TAP results
scripts/local-db.ts, tests/local-db.unit.test.ts
The script captures psql process results and checks TAP output against the test plan. Unit tests cover matching results, failed assertions, missing plans, count mismatches, and nonzero exit codes.
Execute the local SQL test suite
scripts/local-db.ts, supabase/tests/28_channel_device_counts.sql, supabase/tests/88_test_apps_derived_counter_guard.sql
The CLI checks that Postgres is running, installs pgTAP, and runs sorted SQL files individually. It reports per-file results and returns failure if a file fails. Both channel-device-count tests drain pending messages before their assertions.
Expose and invoke the test command
package.json, .github/workflows/tests.yml, AGENTS.md, scripts/local-db.ts
The package script runs the CLI test command. The workflow invokes it after provisioning, and the instructions document the command and prerequisite.

Explanation

The title names the main change: pgTAP tests now run on the local Postgres container in CI. It follows the conventional-commit style and matches the new db:test command and the test_local_db job change. It is 60 characters, which is concise.

Full details: Description check

Explanation

The description covers the summary, test plan, screenshots (marked not applicable with reason), and checklist. It explains what db:test does, why the 28 and 88 test changes were needed, and which CI and manual checks were run. Two checklist items are unchecked (documentation website update and E2E coverage), which are non-critical for this tooling change.

  1. 2 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

28_channel_device_counts.sql assumed the queue was empty. seed.sql fills it,
and only a pg_cron tick between the seed and the tests empties it, so on a
database tested right after provisioning (db:test in CI) the processor
calls returned 10 instead of 1. Drain the queue first, inside the file's
transaction.

tmp_apps_counter_guard_base, drain any seeded channel_device_counts queue
messages using the existing queue processor. Keep the drain inside the test’s

…ard test

Same assumption as 28_channel_device_counts.sql: the processor call expects
exactly one message, but seed.sql's deltas stay queued until a pg_cron
tick. It passed only because it runs after the first tick.
