# This script is used to re-generate all RPC examples for methods listed in doc/schemas/lightning-*.json schema files.
# It uses the pre existing test setup to start nodes, fund channels and execute other RPC calls to generate these examples.
# This test will only run with GENERATE_EXAMPLES=True setup to avoid accidental overwriting of examples with other test executions.
# Set the test TIMEOUT to more than 3 seconds to avoid failures while waiting for the bitcoind response. The `dev-bitcoind-poll` is set to 3 seconds, so a shorter timeout may lead to test failures.
# Note: Different nodes are used to record examples depending upon the availability, quality and volume of the data. For example: Node l1 has been used to listsendpays and l2 for listforwards.
