Tracker

org.scalatest.Tracker
See theTracker companion object
final class Tracker(firstOrdinal: Ordinal)

Class that tracks the progress of a series of Ordinals produced by invoking next and nextNewOldPair on the current Ordinal.

Instances of this class are thread safe. Multiple threads can invoke nextOrdinal and nextTracker concurrently. This facilitates multi-threaded tests that send infoProvided reports concurrently. When using a Dispatcher to execute suites in parallel, the intention is that each Tracker will only be used by one thread. For example, if the optional Dispatcher passed to Suite's implementation of <a href="Suite.html#lifecycle-methods"runNestedSuites is defined, that method will obtain a new Tracker by invoking nextTracker for each nested suite it passes to the Dispatcher.

Value parameters

firstOrdinal

the first Ordinal in the series of Ordinals tracked by this Tracker, which will be used to initialize this Tracker's current Ordinal.

Concrete methods

def nextOrdinal(): Ordinal

Returns the next Ordinal in the series tracked by this Tracker.

Returns the next Ordinal in the series tracked by this Tracker.

This method saves the current Ordinal in a local variable, reassigns the current Ordinal with the value returned by invoking nextOrdinal on the saved Ordinal, then returns the saved Ordinal. As a result, if this method is invoked immediately after construction, this method will return the Ordinal passed as firstOrdinal.

Attributes

Returns

the next Ordinal in the series

def nextTracker(): Tracker

Returns a Tracker initialized with the first element in the tuple returned by invoking nextNewOldPair on the current Ordinal, and reassigns the current Ordinal with the second element that was returned by the nextNewOldPair invocation.

Returns a Tracker initialized with the first element in the tuple returned by invoking nextNewOldPair on the current Ordinal, and reassigns the current Ordinal with the second element that was returned by the nextNewOldPair invocation.

The Ordinal series of the returned Tracker will be placed after all the Ordinals previously returned by invoking nextOrdinal on this Tracker and before all the Ordinals subsequently returned by invoking nextOrdinal on this Tracker in the future. This method is intended to be used when executing nested suites in parallel. Each nested suite passed to the Distributor will get its own Tracker obtained by invoking nextTracker on the current thread's Tracker.

Attributes

Returns

the next Tracker in this series
