Server-side endpoint tests already exist in solitaire_server. This
adds the client-side counterpart: five integration tests in
solitaire_data/tests/sync_round_trip.rs that drive
SolitaireServerClient against an in-process axum::serve harness with
an in-memory SQLite database, covering:
- register_login_push_pull_round_trip — happy path: register, push
non-default stats, pull from a fresh client, assert the merged
payload reflects the pushed values
- pull_after_concurrent_pushes_merges_correctly — two clients on one
user push different games_played values, verify the server-side
merge returns the max
- unauthenticated_pull_returns_authentication_error — pull without
tokens surfaces SyncError::Auth as expected
- jwt_refresh_on_401_succeeds — replace the access token with one
whose exp is two hours stale (same signing key), pull triggers
401 → /api/auth/refresh → retry, asserts the call ultimately
succeeds
- pull_after_account_deletion_returns_default_or_error — register,
push, delete via the trait, confirm the next push surfaces a
result rather than panicking
keyring_core's mock store is installed once per process via Once;
each test uses a unique username so the shared store doesn't
cross-contaminate. Production code in sync_client.rs needed no
changes — the Box<dyn SyncProvider> design plus the mock keyring
were sufficient to drive every flow from outside.
solitaire_server is added as a path dev-dependency along with the
direct crates the harness needs (axum, sqlx, jsonwebtoken, uuid,
chrono, solitaire_sync); no runtime deps changed.
