Struct tracing_mock::collector::MockHandle

pub struct MockHandle(/* private fields */);

A handle which is used to invoke validation of expectations.

The handle is currently only used to assert that all the expected events and spans were seen.

For additional information and examples, see the collector module documentation.

Implementations

impl MockHandle

pub fn assert_finished(&self)

Checks the expectations which were set on the MockCollector.

Calling assert_finished is usually the final part of a test.

Panics

This method will panic if any of the provided expectations are not met.

Examples

use tracing_mock::{collector, expect};

let (collector, handle) = collector::mock()
    .event(expect::event())
    .run_with_handle();

tracing::collect::with_default(collector, || {
    tracing::info!("a");
});

// Check assertions set on the mock collector
handle.assert_finished();
