Interface MockTicker

All Superinterfaces:
Ticker
public interface MockTicker extends Ticker
A fake Ticker that allows the caller control the flow of time. This can be useful when you test time-sensitive logic without waiting for too long or introducing flakiness due to non-deterministic nature of system clock.

  • Method Details

    • initialNanoTime

      default long initialNanoTime()
      Description copied from interface: Ticker
      The initial value used for delay and computations based upon a monotonic time source.
      Specified by:
      initialNanoTime in interface Ticker
      Returns:
      initial value used for delay and computations based upon a monotonic time source.

    • advance

      void advance(long amount, TimeUnit unit)
      Advances the current Ticker.nanoTime() by the given amount of time.
      Parameters:
      amount - the amount of time to advance this ticker by.
      unit - the TimeUnit of amount.

    • advanceMillis

      default void advanceMillis(long amountMillis)
      Advances the current Ticker.nanoTime() by the given amount of time.
      Parameters:
      amountMillis - the number of milliseconds to advance this ticker by.
