Struct ReporterHarness 

pub struct ReporterHarness { /* private fields */ }

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

The matching event receiver is kept alive for the harness’s lifetime, so a reporter built from Self::reporter never sees a spurious disconnect while emitting facts. Its commands are the ones queued when it was built, and nothing more: a prompt with no answer left fails as a disconnect rather than waiting for one that cannot come.

Implementations

impl ReporterHarness

pub fn new() -> Self

Build a harness with empty channels and an empty sink.

pub fn enqueue_response(&mut self, response: Response)

Pre-queue a response to the next prompt the action under test will issue.

Prompt ids start at 0 and increase by one per prompt, so queued responses are matched in issue order: the first call answers the first prompt, the second answers the second, and so on. The reporter reads commands from an unbounded channel, so queuing before execute is enough and no second thread is needed.

Assumes a single reporter built from this harness (the id sequence is not reset by Self::reporter); that matches every current test.

pub fn enqueue_retry(&mut self, response: Response)

Pre-queue a second answer to the prompt the last queued response answered, for when that one is refused: a refused prompt is asked again under the same id.

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.

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

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

Trait Implementations

impl Default for ReporterHarness

fn default() -> Self

Returns the “default value” for a type.
