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:
extern crate assert_cli; assert_cli::assert_cli_output("echo", &["42"], "42").unwrap();
And here is one that will fail:
extern crate assert_cli; assert_cli::assert_cli_output("echo", &["42"], "1337").unwrap();
this will show a nice, colorful diff in your terminal, like this:
-1337
+42
