Poem

In the warren, code now hops with glee,
For tests run swiftly, as quick as can be.
Bun and Jest, a speedy pair,
Catching bugs with thorough care.
Pull requests now dance in line—
CI magic, simply divine!

24-27: Reconsider caching node_modules

Bun stores packages under ~/.bun; caching node_modules adds weight and can introduce stale artifacts without performance gain.

31-36: Switch to the idiomatic bun test command

bun test wraps Jest and yields cleaner logs unless you need Jest-specific flags.
