1//! `bynk test` — discover and run a project's test declarations.
2//!
3//! Delegates to the `bynkc` the driver resolves (`BYNK_BYNKC` → PATH →
4//! sibling-of-`bynk`) and shells `bynkc test`, forwarding every flag verbatim
5//! (v0.138, #487). Unlike `check`/`fmt`, `test` delegates *always*, not only
6//! under an override: it orchestrates external `tsc`/`node`, so it is a
7//! subprocess regardless, and routing it through the driver's resolution is the
8//! whole point — an editor or developer inherits that resolution instead of
9//! locating `bynkc` themselves (the fix direction for #486). The trade-off (a
10//! `bynkc` binary must be present, and the driver↔compiler skew surface stays)
11//! is accepted; the driver at least resolves it more richly than any editor.

24/// Wave 5 §5.4 (findings #40/#72): `args` is the one contract `bynkc test`
25/// and `bynk test` both flatten (`bynk_driver::test_runner::TestArgs`) —
26/// this function's whole body is re-spelling its fields back out as argv
27/// tokens for the shell-out, so a field added there needs no matching change
28/// here beyond this list.
