[−][src]Struct test_process_executor::Executor

pub struct Executor<K, V> where
    K: AsRef<OsStr> + Clone,
    V: AsRef<OsStr> + Clone,  { /* fields omitted */ }

An execution environment, consisting of environment variables which are provided on the launch of each new process.

Implementations

impl<K, V> Executor<K, V> where
    K: AsRef<OsStr> + Clone,
    V: AsRef<OsStr> + Clone, [src]

pub fn new(env: Vec<(K, V)>) -> Self[src]

Initializes a new Executor.

All environment variables are provided to processes launched with the run method.

pub fn run<I, S>(&self, args: I) where
    I: IntoIterator<Item = S>,
    S: AsRef<OsStr>, [src]

Launches a new subprocess and awaits its completion.

Pretty-prints stdout/stderr on failure.

Panics

This method is a little aggressive about panicking; it can totally evolve structured errors if that would be useful. However, given that the primary purpose is testing, this behavior is currently acceptable.

Panics if...

  • args is empty.
  • The sub-process fails to execute.
  • The execution of the sub-process returns a non-zero exit code.
  • The sub-process writes invalid UTF-8 stdout/stderr.
