ReporterHarness

Struct ReporterHarness 

Source
pub struct ReporterHarness { /* private fields */ }
Expand description

Owns the channels and sink needed to build a Reporter for tests.

The matching event receiver and command sender are kept alive for the harness’s lifetime, so a reporter built from Self::reporter never sees a spurious disconnect while emitting facts.

Implementations§

Source§

impl ReporterHarness

Source

pub fn new() -> Self

Build a harness with empty channels and an empty sink.

Source

pub fn respond(&self, prompt_id: u64, response: Response)

Pre-stage an operator response to a prompt the action under test will issue. A reporter allocates prompt ids from zero in order, so the first prompt an action issues has id 0. The response sits in the command channel until the reporter receives it, so call this before running the action.

Source

pub fn reporter(&mut self, step: StepId) -> Reporter<'_>

Build a reporter scoped to the given step. The reporter borrows the harness for its lifetime.

The entropy source is seeded with a fixed test seed, mirroring the runner, so actions that draw values (serials, nonces) work out of the box. Tests that need a specific seed can call Reporter::seed_entropy again.

Source

pub fn facts(&self) -> &[StepFact]

Facts recorded by the harness’s transcript sink, in order.
