TestTimeSource

A time source that has programmatically updatable readings. It is useful as a predictable source of time in tests.

The current reading value can be advanced by the specified duration amount with the operator plusAssign:

val timeSource = TestTimeSource()
timeSource += 10.seconds

Implementation note: the current reading value is stored as a Long number of nanoseconds, thus it's capable to represent a time range of approximately ±292 years. Should the reading value overflow as the result of plusAssign operation, an IllegalStateException is thrown.

open override fun markNow(): ComparableTimeMark

Marks a point in time on this time source.

Since Kotlin 1.3
Link copied to clipboard

Executes the given function block and returns the duration of elapsed time interval.

Since Kotlin 1.3
Link copied to clipboard

Executes the given block and returns an instance of TimedValue class, containing both the result of function execution and the duration of elapsed time interval.

Since Kotlin 1.3

operator fun plusAssign(duration: Duration)

Advances the current reading value of this time source by the specified duration.

Since Kotlin 1.3

protected open override fun read(): Long

This protected method should be overridden to return the current reading of the time source expressed as a Long number in the unit specified by the unit property.
