Crate assert_cli [−] [src]
Test CLI Applications
Currently, this crate only includes basic functionality to check the output of a child process is as expected.
Example
Here's a trivial example:
assert_cli::assert_cli_output("echo", &["42"], "42").unwrap();
And here is one that will fail:
assert_cli::assert_cli_output("echo", &["42"], "1337").unwrap();
this will show a nice, colorful diff in your terminal, like this:
-1337
+42
Alternatively, you can use the assert_cli!
macro:
assert_cli!("echo", &["42"] => Success, "42").unwrap();
Make sure to include the crate as #[macro_use] extern crate assert_cli;
.
