Macro lib::assert_program_args_stdout_contains

macro_rules! assert_program_args_stdout_contains {
    ($a_program:expr, $a_args:expr, $containee:expr $(,)?) => { ... };
    ($a_program:expr, $a_args:expr, $containee:expr, $($message:tt)+) => { ... };
}

Assert a command (built with program and args) stdout string contains a given containee.

• If true, return ().

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

This uses std::String method contains.

• The containee can be a &str, char, a slice of chars, or a function or closure that determines if a character contains.

Examples

// Return Ok
let program = "bin/printf-stdout";
let args = ["%s", "hello"];
let containee = "ell";
assert_program_args_stdout_contains!(&program, &args, containee);
//-> ()

// Panic with error message
let result = panic::catch_unwind(|| {
let program = "bin/printf-stdout";
let args = ["%s", "hello"];
let containee = "zzz";
assert_program_args_stdout_contains!(&program, &args, containee);
//-> panic!
});
assert!(result.is_err());
let actual = result.unwrap_err().downcast::<String>().unwrap().to_string();
let expect = concat!(
    "assertion failed: `assert_program_args_stdout_contains!(a_program, a_args, containee)`\n",
    " a_program label: `&program`,\n",
    " a_program debug: `\"bin/printf-stdout\"`,\n",
    "    a_args label: `&args`,\n",
    "    a_args debug: `[\"%s\", \"hello\"]`,\n",
    " containee label: `containee`,\n",
    " containee debug: `\"zzz\"`,\n",
    "               a: `\"hello\"`,\n",
    "               b: `\"zzz\"`"
);
assert_eq!(actual, expect);
