Struct AssertError 

pub struct AssertError { /* private fields */ }

Assert error (see AssertResult).

Implementations

impl AssertError

pub fn assert(self) -> Assert

Returns the Assert wrapped into the Result produced by the try_ variants of the Assert methods.

Examples

use assert_cmd::prelude::*;

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

let result = Command::new("echo")
    .assert();

match result.try_success() {
        Ok(assert) => {
            assert.stdout(predicate::eq(b"Success\n" as &[u8]));
        }
        Err(err) => {
           err.assert().stdout(predicate::eq(b"Err but some specific output you might want to check\n" as &[u8]));
        }
    }

Trait Implementations

impl Debug for AssertError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AssertError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AssertError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
