## —— Tests and e2e test ---------------------------------------------------------------------------

TEST_THREADS ?= 1

# cargo-nextest is a HARD dependency of `make test`.
#
# nextest changes test semantics vs plain `cargo test`: it runs every test in
# its own process (so serial_test's #[serial] mutex does not serialize across
# tests) and it is the only runner that honours .config/nextest.toml
# [test-groups] (e.g. the ecstore-serial-flaky serialization guard). CI runs
# nextest (.github/actions/setup/action.yml installs it), so a silent fallback
# to `cargo test` would run with different serialization behaviour than CI and
# mask (or invent) flakes.
#
# Installing cargo-nextest:
#   cargo install cargo-nextest --locked          # from source
#   # or a prebuilt binary (faster) via the taiki-e installer / get.nexte.st:
#   #   https://nexte.st/docs/installation/
#
# Escape hatch: set RUSTFS_ALLOW_CARGO_TEST_FALLBACK=1 to run the plain
# `cargo test` fallback anyway. Results are NOT authoritative — semantics
# differ from CI and .config/nextest.toml test-groups will NOT apply.
