Crate substrate_cli_test_utils

Structs

• KillChildOnDrop
• NodeInfo
  Information extracted from a running node.

Functions

• block_hash
• build_substrate
  Builds the Substrate project using the provided arguments.
• extract_info_from_output
  Extract NodeInfo from a running node by parsing its output.
• run_node_for_a_while
  Run the node for a while (3 blocks)
• run_with_timeout
  Run the given future and panic if the timeout is hit.
• start_node
  Starts a new Substrate node in development mode with a temporary chain.
• start_node_inline
  Similar to crate::start_node spawns a node, but works in environments where the substrate binary is not accessible with cargo_bin("substrate-node"), and allows customising the args passed in.
• wait_for_stream_pattern_match
  Takes a readable tokio stream (e.g. from a child process ChildStderr or ChildStdout) and a Regex pattern, and checks each line against the given pattern as it is produced. The function returns OK(()) as soon as a line matching the pattern is found, or an Err if the stream ends without any lines matching the pattern.
• wait_n_finalized_blocks
  Wait for at least n blocks to be finalized from a specified node
