Struct MockProcessExec 

pub struct MockProcessExec {
    pub calls: RefCell<Vec<(String, Vec<String>, Option<String>)>>,
    /* private fields */
}

Mock process executor with scripted responses.

Responses are consumed in FIFO order. The recorded calls can be inspected via MockProcessExec::calls after the run.

Fields

calls: RefCell<Vec<(String, Vec<String>, Option<String>)>>

Record of (cmd, args, stdin) tuples, in invocation order.

Implementations

impl MockProcessExec

pub fn new( responses: impl IntoIterator<Item = Result<ProcessResult, Error>>, ) -> Self

Create a new mock with the given scripted responses.

pub fn recorded_calls(&self) -> Vec<(String, Vec<String>, Option<String>)>

Return a snapshot of recorded calls, cloned out.
