cache_accessor_exposes_a_connected_cache_when_available dialled the literal redis://localhost:6379, so on a developer machine it opened a connection to whatever Redis listens there (Jake's own), not a test server. It now takes its URL from REDIS_URL through test_cache_url() and returns early when the variable is unset, just as it already did when the connect failed. CI sets REDIS_URL on Linux, macOS and coverage, so the connected path still runs there. The URL is read under zone_core's process-wide environment lock so a concurrent test that changes REDIS_URL cannot make it skip. the_test_cache_url_comes_only_from_redis_url pins the helper: None with REDIS_URL unset, the given URL when set.

- Around line 640-653: Update the cache connection handling in the test around
`Cache::connect` so a connection failure when `REDIS_URL` is configured fails
the test instead of returning successfully; keep the early return for an unset
URL and preserve the `state.cache()` assertion.

Fail when the configured cache cannot connect.
When REDIS_URL is set, a failed Cache::connect(&url).await returns success before state.cache() is checked. CI sets REDIS_URL and runs this test through the workspace nextest command, so an unavailable configured cache can pass without exercising the regression assertion.
Suggested fix
- let Ok(cache) = Cache::connect(&url).await else {
- return;
- };
+ let cache = Cache::connect(&url)
+ .await
+ .expect("REDIS_URL must point to a reachable cache");📝 Committable suggestion

What changed
zone_server/src/state.rs(tests only):cache_accessor_exposes_a_connected_cache_when_availabletakes its URL fromREDIS_URLthrough a newtest_cache_url()helper instead of the literalredis://localhost:6379. WithREDIS_URLunset it returns early, as it already did when the connect failed; it never falls back to localhost. The URL is read underzone_core::variables::Variables(the process-wide env lock) so a concurrent test changingREDIS_URLcannot make it skip undercargo test.the_test_cache_url_comes_only_from_redis_url: holds the env lock, asserts the helper returnsNonewithREDIS_URLunset and the given URL when set.Why
The test opened a connection to whatever listened on
localhost:6379. On a developer machine that is the developer's own Redis (on Jake's, his native Redis), not a test server, so a local test run touched real data.How it was verified
test_cache_url()still returning the literal,zone-verify.sh <wt> zr5 scoped - -- -p zone_server -E 'test(/cache/)'failedthe_test_cache_url_comes_only_from_redis_url(left: Some("redis://localhost:6379"),right: None).--all-features -D warnings, migrations, 47/47 cache tests including the integrationcache::*suite against a private Valkey).zone-verify.sh <wt> zr5 ready(private pg17 + Valkey): fmt, clippy--workspace --all-targets --all-features -D warnings, migrations, nextest list, and nextest over the workspace with the CI flags all passed: 6321 tests run, 6321 passed, 62 skipped.REDIS_URL, so the connected path runs there).Not verified
nextest listhad already built it (a defect in the local verify harness, not in zone). Doc tests,sqlx-prepare.sh --check,cargo denyand the dependency-tree guards therefore ran only in CI. The change is#[cfg(test)]-only and touches no dependency, query or doc comment.cache_accessor_exposes_a_connected_cache_when_availabledid not run locally; the local harness excludes it by name as defence in depth. CI exercises it.Behaviour differences
REDIS_URLis set. CI sets it inrust-test.yml(Linuxredis://localhost:6379against the Valkey service, macOSredis://127.0.0.1:56379) andrust-coverage.yml, so CI still exercises the connected path.test_config()and the tests'create_test_config()still carry dummyredis://localhost:6379andpostgres://localhost/…URLs. Those are safe only while the pools built from them stay lazy (PgPool::connect_lazy, and no test connecting a cache fromconfig.redis_url); a test that eagerly connects from those configs would dial the developer's own services again.🤖 Generated with Claude Code
