# assert_cmd

> **Assert `process::Command`** - Easy command initialization and assertions.

[![Crates Status](https://img.shields.io/crates/v/assert_cmd.svg)][Crates.io]

`assert_cmd` aims to simplify the process for doing integration testing of CLIs, including:

- Finding your crate's binary to test

- Assert on the result of your program's run.

## Example

Here's a trivial example:

```rust,no_run

use assert_cmd::Command;

let mut cmd = Command::cargo_bin("bin_fixture").unwrap();

cmd.assert().success();

```

See the [docs](http://docs.rs/assert_cmd) for more.

## Relevant crates

Other crates that might be useful in testing command line programs.

* [escargot][escargot] for more control over configuring the crate's binary.

* [duct][duct] for orchestrating multiple processes.

  * or [commandspec] for easier writing of commands

* [rexpect][rexpect] for testing interactive programs.

* [`assert_fs`][assert_fs] for filesystem fixtures and assertions.

  * or [tempfile][tempfile] for scratchpad directories.

* [dir-diff][dir-diff] for testing file side-effects.

* [cross][cross] for cross-platform testing.

## Testimonials

fitzgen

> assert_cmd is just such a pleasure to use every single time, I fall in love all over again

>

> bravo bravo WG-cli

passcod

> Running commands and dealing with output can be complex in many many ways, so assert_cmd smoothing that is excellent, very much welcome, and improves ergonomics significantly.

>  I have used [assert_cmd] in other projects and I am extremely pleased with it

coreyja

> [assert_cmd] pretty much IS my testing strategy so far, though my app under test is pretty small.

>

> This library has made it really easy to add some test coverage to my project, even when I am just learning how to write Rust!
