`TestEnv` is extracted into its own crate to serve as a framework for testing other block explorer APIs.
BDK TestEnv
This crate sets up a regtest environment with a single [bitcoind] node
connected to an [electrs] instance. This framework provides the infrastructure
for testing chain source crates, e.g., [bdk_chain], [bdk_electrum],
[bdk_esplora], etc.
