Struct CommandOutput 

pub struct CommandOutput {
    pub status: ExitStatus,
    pub stdout: Vec<u8>,
    pub stderr: Vec<u8>,
}

Output captured from a CLI integration test.

command! runs the package’s compiled binary, so this includes the same stdout, stderr, and exit status a user receives. Keep these tests under tests/: Cargo defines the binary path for integration tests, not for a crate’s unit tests.

Fields

status: ExitStatus

The process exit status.

stdout: Vec<u8>

Stdout exactly as the process wrote it.

stderr: Vec<u8>

Stderr exactly as the process wrote it.

Implementations

impl CommandOutput

pub fn assert_success(self) -> Self

Assert that the command succeeded, printing stderr when it did not.

pub fn stdout_text(&self) -> &str

Stdout as UTF-8.

Use the public Self::stdout bytes directly when non-UTF-8 output is intentional.

pub fn stderr_text(&self) -> &str

Stderr as UTF-8.

Use the public Self::stderr bytes directly when non-UTF-8 output is intentional.

Trait Implementations

impl Debug for CommandOutput

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

Formats the value using the given formatter.
