Struct assert_cli::OutputAssertionBuilder

#[must_use]
pub struct OutputAssertionBuilder { /* fields omitted */ }

Assertions for command output.

Methods

impl OutputAssertionBuilder

pub fn contains<O: Into<Content>>(self, output: O) -> Assert

Expect the command's output to contain output.

Examples

extern crate assert_cli;

assert_cli::Assert::command(&["echo", "42"])
    .stdout().contains("42")
    .unwrap();

pub fn is<O: Into<Content>>(self, output: O) -> Assert

Expect the command to output exactly this output.

Examples

extern crate assert_cli;

assert_cli::Assert::command(&["echo", "42"])
    .stdout().is("42")
    .unwrap();

pub fn doesnt_contain<O: Into<Content>>(self, output: O) -> Assert

Expect the command's output to not contain output.

Examples

extern crate assert_cli;

assert_cli::Assert::command(&["echo", "42"])
    .stdout().doesnt_contain("73")
    .unwrap();

pub fn isnt<O: Into<Content>>(self, output: O) -> Assert

Expect the command to output to not be exactly this output.

Examples

extern crate assert_cli;

assert_cli::Assert::command(&["echo", "42"])
    .stdout().isnt("73")
    .unwrap();

pub fn satisfies<F, M>(self, pred: F, msg: M) -> Assert where     F: 'static + Fn(&str) -> bool,     M: Into<String>,

Expect the command output to satisfy the given predicate.

Examples

extern crate assert_cli;

assert_cli::Assert::command(&["echo", "-n", "42"])
    .stdout().satisfies(|x| x.len() == 2, "bad length")
    .unwrap();
