Expand description

Assert a command (built with program and args) stdout string is equal to another.

Pseudocode:
(program1 + args1 ⇒ command ⇒ stdout) = (program2 + args2 ⇒ command ⇒ stdout)

  • If true, return ().

  • Otherwise, call panic! with a message and the values of the expressions with their debug representations.

§Examples

use assertables::*;

let a_program = "bin/printf-stdout";
let a_args = ["%s", "alfa"];
let b_program = "bin/printf-stdout";
let b_args = ["%s%s%s%s", "a", "l", "f", "a"];
assert_program_args_stdout_eq!(&a_program, &a_args, &b_program, &b_args);

// This will panic
let a_program = "bin/printf-stdout";
let a_args = ["%s", "alfa"];
let b_program = "bin/printf-stdout";
let b_args = ["%s%s", "z", "z" ];
assert_program_args_stdout_eq!(&a_program, &a_args, &b_program, &b_args);
// assertion failed: `assert_program_args_stdout_eq!(a_program, a_args, b_program, b_args)`
