Struct MockCliRunner 

pub struct MockCliRunner { /* private fields */ }

A canned-response CliRunner for unit tests.

Register per-command responses before exercising the code under test:

use toride_ssh_core::runner::MockCliRunner;

let mock = MockCliRunner::new();
mock.push_run_response("ssh-keygen", Ok("key generated".into()));
mock.set_tool_exists("ssh-keygen", true);

Implementations

impl MockCliRunner

pub fn new() -> MockCliRunner

Create an empty mock (all calls will return errors by default).

pub fn push_run_response(&self, cmd: &str, result: Result<String, Error>)

Enqueue a response for the given command name.

Responses are returned in FIFO order. If the queue for cmd is exhausted the mock returns Error::CommandFailed.

Panics

Panics if the internal lock is poisoned.

pub fn set_tool_exists(&self, name: &str, exists: bool)

Set whether CliRunner::tool_exists should return true or false for the given tool name.

Panics

Panics if the internal lock is poisoned.

Trait Implementations

impl CliRunner for MockCliRunner

fn run<'life0, 'life1, 'async_trait>( &'life0 self, cmd: &'life1 str, _args: Vec<String>, ) -> Pin<Box<dyn Future<Output = Result<String, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, MockCliRunner: 'async_trait,

Run an external command and return its captured stdout.

fn run_with_env<'life0, 'life1, 'async_trait>( &'life0 self, cmd: &'life1 str, _args: Vec<String>, _env: Vec<(String, String)>, ) -> Pin<Box<dyn Future<Output = Result<String, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, MockCliRunner: 'async_trait,

Run an external command with additional environment variables and return its captured stdout.

fn tool_exists(&self, name: &str) -> bool

Return true when the given tool is available on PATH.

impl Default for MockCliRunner

fn default() -> MockCliRunner

Returns the “default value” for a type.
