# Running the suites the plain regression doesn't reach
|
|
|
|
Status: 2026-09-19.
|
|
|
|
`cargo test -p tests` runs everything that needs nothing but a store on
|
|
disk. The fork's own feature suites are `#[ignore]`d on top of that,
|
|
because each one needs something the plain run hasn't got: a container, a
|
|
`STORE` the harness only builds on request, or, for the eight `*_compat`
|
|
tests, a copy of INBUXA's data. A green regression therefore says nothing
|
|
about them, and they have to be run by name.
|
|
|
|
The compat eight have their own runbook, `compat-tests.md`. This one
|
|
covers the rest.
|
|
|
|
## Before any of them
|
|
|
|
- Docker, for every suite whose "Needs" column names a container. The
|
|
suites start and reuse their own containers through the `ensure_*`
|
|
helpers in `tests/src/utils/containers.rs`; nothing has to be started by
|
|
hand.
|
|
- `RUST_MIN_STACK=8388608`, or `smtp::inbound::data::data` and some suites
|
|
overflow the 2 MiB test-thread stack.
|
|
- `CARGO_TARGET_DIR=target TMPDIR=$PWD/target/tmp`, a fresh `TMPDIR` per
|
|
run.
|
|
- **One at a time.** Each suite starts a server on the same fixed ports,
|
|
and the machine is CPU-bound: a second suite, or a build running
|
|
alongside, makes the timing checks flake.
|
|
|
|
## The suites
|
|
|
|
| Suite | Feature | Needs | `STORE` |
|
|
|---|---|---|---|
|
|
| `scim::scim_tests` | 7, SCIM | Nothing (`SCIM_CONFORMANCE=1` adds the third-party clients, in a container) | default |
|
|
| `scim::scim_oidc_tests` | 7 and 9 (test 5) | Keycloak | default |
|
|
| `directory::per_domain::per_domain_directory_tests` | 9, per-domain directories | Nothing; needs the `sqlite` feature | default |
|
|
| `store::scaleout::scaleout_blob_tests` | 8, scale-out storage (tests 2 to 8) | Nothing: the members are directories | default |
|
|
| `store::scaleout::scaleout_memory_tests` | 8 (tests 20, 22, 23) | Redis; needs the `redis` feature | default |
|
|
| `store::replica::replica_tests` | 8 (tests 9, 10, 12 to 15) | PostgreSQL primary and hot standby | `PostgreSqlReplicated` |
|
|
| `store::replica_cluster::replica_cluster_tests` | 8 (test 11) | The same pair, and Redis | `PostgreSqlReplicated` |
|
|
| `store::replica_mysql::mysql_replica_tests` | 8 (test 17) | MySQL source and replica, GTIDs | `MySqlReplicated` |
|
|
| `store::replica_mysql::mysql_replica_position_tests` | 8 (tests 18, 19) | MySQL source and replica, by binary log position | `MySqlReplicatedPosition` |
|
|
|
|
`system::{ai,branding,masked_email,monitoring,tenant,undelete}_tests` are
|
|
also `#[ignore]`d, but only as a way to run one suite alone: the same code
|
|
runs inside `system_tests`, which the regression does run.
|
|
|
|
## Running one
|
|
|
|
```
|
|
CARGO_TARGET_DIR=target TMPDIR=$PWD/target/tmp RUST_MIN_STACK=8388608 \
|
|
STORE=<store> cargo test -p tests --features <backends> <suite> -- --ignored
|
|
```
|
|
|
|
`<suite>` is the test's name, such as `scim_tests` or `replica_tests`, and
|
|
`--exact` with its full path if the name matches more than one. The three
|
|
replicated `STORE` values are the harness's own (`tests/src/utils/storage.rs`);
|
|
they bring up the pair they name and point the server at the primary.
|
|
|
|
For example:
|
|
|
|
```
|
|
STORE=PostgreSqlReplicated cargo test -p tests --features postgres,redis \
|
|
replica_cluster_tests -- --ignored
|
|
```
|
|
|
|
## What a plain regression leaves failing
|
|
|
|
`STORE=RocksDb cargo test -p tests -- --test-threads=1` was 86 passed, 4
|
|
failed, 27 ignored on 2026-09-19. None of the four was a fork regression,
|
|
and three are the invocation or the environment rather than the code:
|
|
|
|
- `smtp::inbound::antispam::antispam` fails every time. Its rules URL
|
|
defaults to `file:///Users/me/code/spam-filter/spam-filter-rules.json.gz`,
|
|
a path from the upstream import that exists on no machine here, so no
|
|
rules load and every tag scores 0.00 against an expectation full of
|
|
weights. Give it `SPAM_RULES_URL`.
|
|
- `cluster::broadcast::cluster_tests` needs `COORDINATOR=Redis` (or `Nats`)
|
|
and a store the nodes can share: it passes on `STORE=PostgreSql`, and
|
|
can't work on RocksDb, where each node gets its own.
|
|
- `smtp::outbound::lmtp::lmtp_delivery` counted three DSNs where it wanted
|
|
four, and passes on its own: queue timing under a loaded sequential run.
|
|
- `automation::automation_tests` fails against pebble with
|
|
`400 malformed: "Cannot update challenge with status processing, only
|
|
status pending"`. `crates/common/src/network/acme/order.rs` re-POSTs the
|
|
challenge each time it polls an authorization that is still pending;
|
|
pebble accepts that only while the challenge itself is pending. Upstream
|
|
code, untouched by the fork, and unfixed: worth treating as a real
|
|
renewal bug rather than a test artefact.
|
|
|
|
## When one fails
|
|
|
|
The containers are reused between runs, so a suite that fails in a way its
|
|
own assertions don't explain is worth re-running once against fresh ones:
|
|
`docker rm -f` the containers it names (they are all prefixed
|
|
`inbuxa-test-`) and run it again. A replica pair left paused or stopped by
|
|
an interrupted run is the usual cause — `replica_tests` pauses WAL replay,
|
|
and `mysql_replica_position_tests` changes the replica's parallel-apply
|
|
settings, both of which they restore only if they finish.
