Class TestTransport.SwitchableLoggedBehavior<A,​B>

  • All Implemented Interfaces:
    scala.Function1<A,​scala.concurrent.Future<B>>
    Enclosing class:
    TestTransport

    public static class TestTransport.SwitchableLoggedBehavior<A,​B>
    extends java.lang.Object
    implements scala.Function1<A,​scala.concurrent.Future<B>>
    Test utility to make behavior of functions that return some Future[B] controllable from tests. This tool is able to overwrite default behavior with any generic behavior, including failure, and exposes control to the timing of the completion of the returned future.

    The utility is implemented as a stack of behaviors, where the behavior on the top of the stack represents the currently active behavior. The bottom of the stack always contains the defaultBehavior which can not be popped out.

    param: defaultBehavior The original behavior that might be overwritten. It is always possible to restore this behavior

    param: logCallback Function that will be called independently of the current active behavior

    type parameter A: - Parameter type of the wrapped function. If it takes multiple parameters it must be wrapped in a tuple.

    type parameter B: - Type parameter of the future that the original function returns.

      • apply

        public scala.concurrent.Future<B> apply​(A params)
        Applies the current behavior, and invokes the callback.

        Specified by:
        apply in interface scala.Function1<A,​B>
        Parameters:
        params - The parameters of this behavior.
        Returns:
        The result of this behavior wrapped in a future.
      • pop

        public void pop()
        Restores the previous behavior.
      • push

        public void push​(scala.Function1<A,​scala.concurrent.Future<B>> behavior)
        Changes the current behavior to the provided one.

        Parameters:
        behavior - Function that takes a parameter type A and returns a Future[B].
      • pushConstant

        public void pushConstant​(B c)
        Changes the behavior to return a completed future with the given constant value.

        Parameters:
        c - The constant the future will be completed with.
      • pushDelayed

        public scala.concurrent.Promise<scala.runtime.BoxedUnit> pushDelayed()
        Enables control of the completion of the previously active behavior. Wraps the previous behavior in a new one, returns a control promise that starts the original behavior after the control promise is completed.

        Returns:
        A promise, which delays the completion of the original future until after this promise is completed.
      • pushError

        public void pushError​(java.lang.Throwable e)
        Changes the current behavior to return a failed future containing the given Throwable.

        Parameters:
        e - The throwable the failed future will contain.
