Overview

In-memory connector for tests. Responses can be static values, sequences (consumed in order, last value repeats) or procs receiving the params.

stub = BlockGiven::Connectors::Stub.new(
"eth_blockNumber" => BlockGiven::Connectors::Stub.sequence("0x10", "0x11"),
"eth_call" => ->(params) { "0x" + "0" * 63 + "1" }
)
stub.calls # => [["eth_blockNumber", []], ...]
