Module assert_cmd::cargo

Simplify running bins in a Cargo project.

CommandCargoExt is an extension trait for Command to easily launch a crate's binaries.

In addition, the underlying functions for looking up the crate's binaries are exposed to allow for optimizations, if needed.

Examples

Simple case:

use assert_cmd::prelude::*;

use std::process::Command;

Command::main_binary()
    .unwrap()
    .unwrap();

Caching the binary's location:

use assert_cmd::prelude::*;

use std::process::Command;

let bin_under_test = assert_cmd::cargo::main_binary_path().unwrap();
Command::new(&bin_under_test)
    .unwrap();

Tip: Use lazy_static to cache bin_under_test across test functions.

Structs

CargoError

Error when finding crate binary.

Traits
