Overview

Package gatedreporter says how much of a run came from one compilation.

It exists because the gated path could stop engaging without anything saying so. `Gated` and `FellBack` are exact counters, and until this they were counters nobody printed: a run that gated every mutant and a run that gated none produced identical output, and the difference was found only by dropping a panic into `TestAll` by hand and watching it not fire. A number that is not printed is a number that cannot go wrong in front of anyone.

Types

type GatedReporter

type GatedReporter struct {
	// contains filtered or unexported fields
}

func New

func New(logger ditto.Logger, gates Gates, delegate ditto.Reporter) *GatedReporter

func (*GatedReporter) AddDiagnostic

func (r *GatedReporter) AddDiagnostic(diagnostic *ditto.Diagnostic)

func (*GatedReporter) Summarize

func (r *GatedReporter) Summarize() result.Result[any]

Summarize reports the counts after the verdicts, because they describe how the run was executed rather than what it found. It never changes the verdict.

type Gates

type Gates interface {
	Gated() int
	FellBack() int
}

Gates is the pair of counters a gated laboratory keeps.
