rustfs/.config/nextest.toml

# nextest configuration for RustFS.
#
# Serialize two known load-sensitive / global-state-sharing ecstore test groups
# so the full parallel nextest suite stops producing spurious failures
# (backlog #937). These tests pass in isolation but flake under the loaded
# parallel run for two distinct reasons:
#
#   * store::bucket::tests::bucket_delete_* share process/global state (disk
#     registry, lock client) and race make_bucket into InsufficientWriteQuorum
#     when run concurrently with other ecstore tests.
#   * bucket_lifecycle_ops::tests::concurrent_resend_same_part_commits_one_generation
#     asserts a lock-acquire correctness property whose serialized cross-disk
#     commits exceed the (already max'd, 60s) acquire deadline only when the
#     suite saturates disk I/O.
#
# serial_test's #[serial] attribute does NOT serialize these across runs:
# nextest executes each test in its own process, where the in-process
# serial_test mutex has no effect. A nextest test-group with max-threads = 1 is
# the mechanism that actually serializes across nextest's process boundary.
#
# ---------------------------------------------------------------------------
# Profiles
# ---------------------------------------------------------------------------
# The `default` profile is what local `cargo nextest run` uses. It NEVER
# retries: a red test locally means a real failure to investigate, not noise to
# paper over. The `ci` profile (below) is the strict CI gate: global
# retries = 0 so a new race's first occurrence is never masked, plus a
# narrowly-scoped quarantine list (retries = 2) for tests with a tracked OPEN
# flake issue. Flake policy lives in docs/testing/README.md.

# RULES (enforced by review, see docs/testing/README.md):
#   * Every entry MUST link exactly one OPEN issue tracking the flake.
#   * An entry stays until the issue is fixed (test made robust) or the test is
#     deleted — 30-day policy. No entry may exist without a live issue link.
#
# Each entry also re-declares the `ecstore-serial-flaky` test-group so the
# serialization holds under the ci profile (nextest evaluates a named
# profile's own overrides list, not the default profile's).
# ===========================================================================

# PR smoke subset of the e2e_test crate (backlog#1149 ci-4). This profile is
# the single wiring mechanism for e2e tests in CI: other suites join by
# extending this filter (or a sibling profile), never by adding ad-hoc e2e
# jobs to ci.yml. Admission criteria (see crates/e2e_test/README.md): fast,
# single-node topology, no external dependencies (no awscurl / Vault / fixed
# ports / pre-started server), no #[ignore].
#
# Each e2e test spawns its own rustfs server on a random port with an isolated
# temp dir (crates/e2e_test/src/common.rs), so the subset is parallel-safe.
