Subject: Test new behavior in create_bolt11_invoice
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=2a4a470c988146c1f7a8f3aad7d7e4029d736984;p=rust-lightning

Test new behavior in create_bolt11_invoice

Bolt11InvoiceParameters allows for setting currency and
duration_since_epoch. If currency is not set, test that the one
corresponding to ChannelManager's chain hash is usd. If
duration_since_epoch, is not set then highest seen timestamp is used in
non-std compilations.
