Functions

func CleanupPath

func CleanupPath(path string)

CleanupPath detects the existence of test DB file and removes it if found

func PathOfTempFile

func PathOfTempFile(dirName string) (string, error)

PathOfTempFile returns path of a new temporary file

func RandomPort

func RandomPort() int

RandomPort returns a random port number between 30000 and 50000

func SignalChan

func SignalChan(interval, timeout time.Duration) <-chan struct{}

SignalChan returns a channel that will be written every interval until timeout

func TimestampNow

func TimestampNow() time.Time

TimestampNow returns current time from new clock

func WaitUntil

func WaitUntil(interval, timeout time.Duration, f CheckCondition) error

WaitUntil periodically checks whether the condition specified in CheckCondition function is satisfied If an error is returned, it either comes from CheckCondition function or time is up before the given condition is satisfied
