Testing

ReifyDB has a built-in test framework. Write tests alongside your schema, seed data with test procedures, and assert results inline.

Tests and Test Procedures

CREATE NAMESPACE tg;
CREATE TABLE tg::items { id: int4, name: utf8 };
CREATE TEST PROCEDURE tg::seed AS {
  INSERT tg::items [{ id: 1, name: 'one' }, { id: 2, name: 'two' }]
};
CREATE TEST tg::query_all {
  CALL tg::seed();
  FROM tg::items | ASSERT { id > 0 }
};
CREATE TEST tg::filter_one {
  CALL tg::seed();
  FROM tg::items | FILTER name == 'one' | ASSERT { id == 1 }
};
RUN TESTS tg | MAP { name, namespace, outcome }

CREATE TEST PROCEDURE defines reusable setup logic. CREATE TEST defines a test that calls setup procedures, runs queries, and asserts results. Each test runs in isolation — data from one test never leaks into another.

Assert Expressions

ASSERT checks that a condition is true. Use it inline in pipelines or standalone. Tests fail on the first assertion failure.
