quicknode-cli 0.1.10

//! Shared helpers for integration tests.
//!
//! The bulk of CLI integration tests run *in-process* (no subprocess) for
//! speed and reliability. We parse with `Cli::try_parse_from`, point the SDK
//! at a `wiremock` server via `--base-url`, and dispatch with `Cli::run()`.
//! Stdout is NOT captured by the in-process harness — assertions go through
//! exit codes and wiremock request matchers. Tests that need to assert on
//! rendered output live in `tests/cli_smoke.rs` and run via `assert_cmd`.
