	.with_retry_config(RetryConfig::new(

	async fn retry_config_validation() {
	let retry_config = RetryConfig::new(5, Duration::from_millis(100), Duration::from_secs(10))
	.with_backoff_multiplier(1.5);
	assert_eq!(retry_config.max_retries, 5);
	assert_eq!(retry_config.initial_backoff, Duration::from_millis(100));
	assert_eq!(retry_config.max_backoff, Duration::from_secs(10));
	assert_eq!(retry_config.backoff_multiplier, 1.5);
	}
	}

Both tests assert field values for RemoteSigningConfig and RetryConfig, which
involve no remote signer client or gRPC channel(s), hence should be appropriate for
unit test section in config.rs
