Running tests

jadpo test owns everything a test run needs, so nothing about it appears in your source (Testing). It starts a disposable local PostgreSQL, from the PostgreSQL programs installed on your machine, or uses JADPO_TEST_DATABASE_URL in CI. It builds one template database from the migrations and copies it for each test, so tests run in parallel. --keep-failed keeps a failed test's database, and --kind route runs one kind of test. The report lists each failed test with the failure it got and the one it expected.

The compiler also generates tests from facts it already has:

• every route refuses bad input with { field, rule } details;
• every declared failure reaches the client in the right envelope and status;
• no output has a field its type doesn't declare.

They run with your tests, and the report shows them under the route they test.

Not built yet: --affected, which runs the tests a change reaches.
