Constants

const Magnitude = 1000

Magnitude is the upper-bound of random numbers used in profile tests.

Functions

func CheckedMerge

func CheckedMerge(t *testing.T, aggInto, aggFrom aggregator.Aggregator, descriptor *sdkapi.Descriptor)

CheckedMerge verifies aggFrom merges into aggInto with the scope of descriptor.

func CheckedUpdate

func CheckedUpdate(t *testing.T, agg aggregator.Aggregator, n number.Number, descriptor *sdkapi.Descriptor)

CheckedUpdate performs the same range test the SDK does on behalf of the aggregator.

func NewAggregatorTest

func NewAggregatorTest(mkind sdkapi.InstrumentKind, nkind number.Kind) *sdkapi.Descriptor

NewAggregatorTest returns a descriptor for mkind and nkind.

func RunProfiles

func RunProfiles(t *testing.T, f func(*testing.T, Profile))

RunProfiles runs all test profile against the factory function f.

func SynchronizedMoveResetTest

func SynchronizedMoveResetTest(t *testing.T, mkind sdkapi.InstrumentKind, nf func(*sdkapi.Descriptor) aggregator.Aggregator)

SynchronizedMoveResetTest tests SynchronizedMove behavior for an aggregator during resets.

func TestMain

func TestMain(m *testing.M)

TestMain ensures local struct alignment prior to running tests.
