Testimonials

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!
