Eventually

object Eventually extends Eventually

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

$ scala -cp scalatest-1.8.jar
Welcome to Scala version 2.9.1.final (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_29).
Type in expressions to have them evaluated.

  10. def eventually[T](fun: ⇒ T)(implicit config: PatienceConfig): T

    Invokes the passed by-name parameter repeatedly until it either succeeds, or a configured maximum amount of time has passed, sleeping a configured interval between attempts.

    Invokes the passed by-name parameter repeatedly until it either succeeds, or a configured maximum amount of time has passed, sleeping a configured interval between attempts.

    The by-name parameter "succeeds" if it returns a result. It "fails" if it throws any exception that would normally cause a test to fail. (These are any exceptions except TestPendingException and Errors listed in the Treatment of java.lang.Errors section of the documentation of trait Suite.)

    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.

    fun

    the by-name parameter to repeatedly invoke

    config

    the PatienceConfig object containing the timeout and interval parameters

    returns

    the result of invoking the fun by-name parameter, the first time it succeeds

    Invokes the passed by-name parameter repeatedly until it either succeeds, or a configured maximum amount of time has passed, sleeping a configured interval between attempts.

    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 value contained in the passed interval parameter.

  23. 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.

    Definition Classes

    Exceptions thrown
    IllegalArgumentException

    if the value returned from spanScaleFactor is less than zero

  24. 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.
