Concept trait for futures, instances of which are passed to the whenReady
methods of trait Futures.
Configuration object for asynchronous constructs, such as those provided by traits Eventually and
Waiters.
Configuration object for asynchronous constructs, such as those provided by traits Eventually and

The default values for the parameters are:

the maximum amount of time to wait for an asynchronous operation to complete before giving up and throwing
TestFailedException.
the amount of time to sleep between each check of the status of an asynchronous operation when polling
Implicitly converts a scala.concurrent.Future[T] to
FutureConcept[T], allowing you to invoke the methods
defined on FutureConcept on a Scala Future, as well as to pass a Scala future
to the whenReady methods of supertrait Futures.

See the documentation for supertrait Futures for the details on the syntax this trait provides
for testing with Java futures.
If the eitherValue method of the underlying Scala future returns a scala.Some containing a
scala.util.Failure containing a java.util.concurrent.ExecutionException, and this
exception contains a non-null cause, that cause will be included in the TestFailedException as its cause. The
ExecutionException will be be included as the TestFailedException's cause only if the
ExecutionException's cause is null.
The isExpired method of the returned FutureConcept will always return false, because
the underlying type, scala.concurrent.Future, does not support the notion of expiration. Likewise, the isCanceled
method of the returned FutureConcept will always return false, because
the underlying type, scala.concurrent.Future, does not support the notion of cancelation.

specifies the amount of time to sleep after a retry.

Scales the passed Span by the Double factor returned
by spanScaleFactor.
Scales the passed Span by the Double factor returned
by spanScaleFactor.
The Span is scaled by invoking its scaledBy method,
thus this method has the same behavior:
The value returned by spanScaleFactor can be any positive number or zero,
including a fractional number. A number greater than one will scale the Span
up to a larger value. A fractional number will scale it down to a smaller value. A
factor of 1.0 will cause the exact same Span to be returned. A
factor of zero will cause Span.ZeroLength to be returned.
If overflow occurs, Span.Max will be returned. If underflow occurs,
Span.ZeroLength will be returned.
IllegalArgumentException if the value returned from spanScaleFactor
is less than zero
The factor by which the scaled method will scale Spans.
The factor by which the scaled method will scale Spans.
The default implementation of this method will return the span scale factor that
was specified for the run, or 1.0 if no factor was specified. For example, you can specify a span scale factor when invoking ScalaTest
via the command line by passing a -F argument to Runner.
Returns a Timeout configuration parameter containing the passed value, which
specifies the maximum amount to wait for an asynchronous operation to complete.
Returns a Timeout configuration parameter containing the passed value, which
specifies the maximum amount to wait for an asynchronous operation to complete.
Queries the passed future repeatedly until it either is ready, or a configured maximum amount of time has passed, sleeping a configured interval between attempts; and when ready, passes the future's value to the passed function.

The maximum amount of time in milliseconds to tolerate unsuccessful attempts before giving up is configured by the timeout field of
the PatienceConfig passed implicitly as the last parameter.
The interval to sleep between attempts is configured by the interval field of
the PatienceConfig passed implicitly as the last parameter.
If the eitherValue method of the underlying Scala future returns a scala.Some containing a

exception contains a non-null cause, that cause will be included in the TestFailedException as its cause. The
ExecutionException will be be included as the TestFailedException's cause only if the
ExecutionException's cause is null.

Companion object that facilitates the importing of
ScalaFuturesmembers as an alternative to mixing in the trait. One use case is to importScalaFutures's members so you can use them in the Scala interpreter.
