Types

type Action

type Action string

Action is one of a fixed set of actions describing a single emitted event.

const (
	ActionRun    Action = "run"    // test has started running
	ActionPause  Action = "pause"  // test has been paused
	ActionCont   Action = "cont"   // the test has continued running
	ActionPass   Action = "pass"   // test passed
	ActionBench  Action = "bench"  // benchmark printed log output but did not fail
	ActionFail   Action = "fail"   // test or benchmark failed
	ActionOutput Action = "output" // test printed output
	ActionSkip   Action = "skip"   // test was skipped or the package contained no tests
)

Prefixed with Action for convenience.

func (Action) String

func (a Action) String() string

type Event

type Event struct {
	// Action can be one of:
	// run, pause, cont, pass, bench, fail, output, skip
	Action Action

	// Portion of the test's output (standard output and standard error merged together)
	Output string

	// Time at which the the event occurred, encodes as an RFC3339-format string.
	// It is conventionally omitted for cached test results.
	Time time.Time

	// The Package field, if present, specifies the package being tested.
	// When the go command runs parallel tests in -json mode, events from
	// different tests are interlaced; the Package field allows readers to separate them.
	Package string

	// The Test field, if present, specifies the test, example, or benchmark
	// function that caused the event. Events for the overall package test do not set Test.
	Test string

	// Elapsed is time elapsed (in seconds) for the specific test or
	// the overall package test that passed or failed.
	Elapsed float64
}

Event represents a single line of json output from go test with the -json flag.

	Package string
	Events  []*Event
