Testing Code

None of this code ships on the product itself, but it does get used for testing purposes.

Background

pytest is used to track test cases and fixtures, etc
most test code is desktop (simulator), but it can also validate stuff from/to the device
some tests might only be possible in 'devmode': a unit that has booted w/ non-standard bootrom
some tests may be destructive for funds/seeds/wallets
most unit tests will work only on simulator because the useful hooks are too dangerous in product
you need a testnet bitcoind running for some tests (will be skipped if not present)

pass argument "--sim" or "--dev" to select simulator or real device
will skip tests that are inappropriate
and/or use "marker" for bitcoind interaction: "-m bitcoind"
with "--dev" include "--manual" to require operator to press X/OK at times (also needs -s), so:

--dev --manual -s

test all QR code related cases with:

py.test -m qrcode
txn signing where an unfinalized PSBT is created (low-R tests)

py.test -m unfinalized
"bitcoind" which means test would be skipped if you don't have bitcoin core running locally (on testnet)
