PatienceConfiguration

Trait providing methods and classes used to configure timeouts and, where relevant, the interval between retries.

This trait is called PatienceConfiguration because it allows configuration of two values related to patience: The timeout specifies how much time asynchronous operations will be given to succeed before giving up. The interval specifies how much time to wait between checks to determine success when polling.

The default values for timeout and interval provided by trait PatienceConfiguration are tuned for unit testing, where running tests as fast as possible is a high priority and subsystems requiring asynchronous operations are therefore often replaced by mocks. This table shows the default values:

Configuration Parameter	Default Value
`timeout`	`scaled(150 milliseconds)`
`interval`	`scaled(15 milliseconds)`

Values more appropriate to integration testing, where asynchronous operations tend to take longer because the tests are run against the actual subsytems (not mocks), can be obtained by mixing in trait IntegrationPatience.

The default values of both timeout and interval are passed to the scaled method, inherited from ScaledTimeSpans, so that the defaults can be scaled up or down together with other scaled time spans. See the documentation for trait ScaledTimeSpans for more information.

Timeouts are used by the eventually methods of trait Eventually and the await method of class Waiter, a member of trait AsyncAssertions. Intervals are used by the eventually methods.

final def scaled(span: Span): Span

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.

def spanScaleFactor: Double

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.
