Struct TestProcess 

pub struct TestProcess { /* private fields */ }

Child process with isolated working directory, captured logs, and kill-on-drop cleanup.

Implementations

impl TestProcess

pub fn spawn(name: &str, command: &mut Command) -> Self

Spawns command in a fresh temporary directory and captures stdout/stderr to files.

Callers own product-specific arguments and environment variables. This helper owns only process lifecycle and diagnostics.

Panics

Panics when the fixture name is invalid, its temporary directory or log files cannot be created, or the child process cannot be spawned.

pub fn name(&self) -> &str

Returns the fixture name used in diagnostics.

pub fn runtime_dir(&self) -> &Path

Returns the isolated working directory.

pub fn terminate(&mut self)

Kills the child process and waits for it to exit. Repeated calls are harmless.

pub fn terminate_gracefully(&mut self, timeout: Duration) -> bool

Sends SIGTERM and waits for the child to exit within timeout.

Panics

Panics when the signal command fails, SIGTERM is rejected, or child status cannot be read.

pub fn assert_running(&mut self)

Panics with captured logs when the child has exited unexpectedly.

Panics

Panics when the fixture has stopped, child status cannot be queried, or the child exited.

pub fn diagnostics(&self) -> String

Returns the tail of stdout and stderr for failure reporting.
