Expand description

Assert a command (built with program and args) stdout string is greater than or equal to an expression.

Pseudocode:
(program1 + args1 ⇒ command ⇒ stdout ⇒ string) ≥ (expr into string)

  • If true, return ().

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

§Examples


let program = "bin/printf-stdout";
let args = ["%s", "hello"];
let s = String::from("hello");
assert_program_args_stdout_ge_expr!(&program, &args, s);

let program = "bin/printf-stdout";
let args = ["%s", "hello"];
let s = String::from("zzz");
assert_program_args_stdout_ge_expr!(&program, &args, s);
// assertion failed: `assert_program_args_stdout_ge_expr!(a_program, a_args, b_expr)`
