Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR adds a public testing package, but unresolved dependency constraints may prevent consumers from resolving compatible releases, and inconsistent authentication fixtures could make application tests pass or fail against the wrong user identity; the removed helpers also lack migration guidance.

exact 2.16.0 version to the compatible caret constraint ^2.16.0 unless lockstep
versioning is intentional; if retaining the exact constraint, document that
policy. Also wrap the description and repository YAML values to keep lines

Follow-up to #1745, which consolidated the test helpers of all the client suites into
supabase_common's testing library. This PR breaks those helpers out into a new publishedsupabase_testingpackage aimed at consumers, keepssupabase_commona purely internal package, and adds the helpers and documentation that make testing an app against Supabase easy.The package split
packages/supabase_testingis a new published package holding the customer-facing helpers: the mock HTTP clients, JWT builders, auth fixtures and realtime frame builders from refactor: share the test helpers through supabase_common #1745. All nine client package suites now consume them from there as a dev dependency.supabase_commongoes back to its internal branding (README, pubspec description and topics). Itstesting.dartshrinks back to the repo-internal local stack configuration, which is tied to this repository'ssupabase/config.tomland is not useful to consumers.supabase_testingis excluded from the capability-matrix scan, since test helpers are not SDK client surface.New helpers
Built on top of the moved primitives, verified by their own test suite:
MockSupabaseHttpClient: answers requests from stubs registered per endpoint, with shorthands for the service layouts so tests never spell out URL paths:stubTable(/rest/v1/<table>),stubRpc,stubEdgeFunctionandstubSignIn(a working token endpoint). The latest matching stub wins,timeslimits how often a stub answers so call sequences can be modeled, and an unmatched request throws aStateErrornaming the request and the registered stubs. Every answered request is recorded with its body already read (request.jsonBody), so tests can assert on what the code under test sent.testSupabaseClient: aSupabaseClientwired for tests, removing the footguns of constructing one by hand: in-memory pkce storage, token auto refresh off so no timer outlives the test, and an unsigned anon JWT as the default API key.signInTestUser: puts a client into a signed-in state without any network traffic (throughrecoverSessionwith generated fixtures), so any test can run as an authenticated user with custom id, email, role and claims.decodeTestJwtClaims: reads claims back out of a token for assertions.Documentation
supabase_testingREADME is a full testing guide: quickstart, stubbing each service, error and sequence stubbing, asserting on recorded requests, running tests as a signed-in user, testing sign-in flows, realtime frames, wiringSupabase.initializein Flutter widget tests, and when to reach for a real local stack instead.Every code sample in the READMEs was executed as a real test before being inlined, including the Flutter
