Macro cargo_bin 

macro_rules! cargo_bin {
    () => { ... };
    ($bin_target_name:expr) => { ... };
}

The absolute path to a binary target’s executable.

The bin_target_name is the name of the binary target, exactly as-is.

NOTE: This is only set when building an integration test or benchmark.

Example

use assert_cmd::prelude::*;
use assert_cmd::cargo::cargo_bin;

use std::process::Command;

let mut cmd = Command::new(cargo_bin!())
let output = cmd.unwrap();
