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");
