Assertprocess::Command- Easy command initialization and assertions.
assert_cmdaims 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.
Add to your
[dependencies] assert_cmd = "1.0.1"
Here's a trivial example:
let mut cmd = Command::cargo_bin("bin_fixture").unwrap(); cmd.assert().success();
See the docs for more.
Other crates that might be useful in testing command line programs. * escargot for more control over configurin the crate's binary. * duct for orchestrating multiple processes. * or commandspec for easier writing of commands * rexpect for testing interactive programs. *tempfile for scratchpad directories. * dir-diff for testing file side-effects.

assert_cmd is just such a pleasure to use every single time, I fall in love all over again
bravo bravo WG-cli
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
[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!
