Trait assert_cmd::assert::IntoOutputPredicate[−][src]

pub trait IntoOutputPredicate<P> where
    P: Predicate<[u8]>, {
    type Predicate;
    fn into_output(self) -> P;
}
Expand description

Used by Assert::stdout and Assert::stderr to convert Self into the needed [predicates_core::Predicate<[u8]>].

Examples

use assert_cmd::prelude::*;

use std::process::Command;
use predicates::prelude::*;

Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("stdout", "hello")
    .env("stderr", "world")
    .assert()
    .stdout(predicate::str::diff("hello\n").from_utf8());

// which can be shortened to:
Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("stdout", "hello")
    .env("stderr", "world")
    .assert()
    .stdout("hello\n");
