Akka.TestKit Configuration
Below is the default HOCON configuration for the base Akka.TestKit
package.

# This is the reference config file that contains all the default settings.
akka {
# Replace the default value, ["Akka.Event.DefaultLogger"], with TestEventListener
# This logger behaves exactly like DefaultLogger, but makes it possible
# to use EventFiltering. If no filter is specified it logs to StdOut just like
# DefaultLogger.
loggers = ["Akka.TestKit.TestEventListener, Akka.TestKit"]
test {
# factor by which to scale timeouts during tests, e.g. to account for shared
# build system load
timefactor = 1.0
# duration of EventFilter.intercept waits after the block is finished until
# all required messages are received
filter-leeway = 3s
# duration to wait in expectMsg and friends outside of within() block
# by default
single-expect-default = 3s
# The timeout that is added as an implicit by DefaultTimeout trait
# This is used for Ask-pattern
default-timeout = 5s
calling-thread-dispatcher {
type = "Akka.TestKit.CallingThreadDispatcherConfigurator, Akka.TestKit"
throughput = 2147483647
}
test-actor.dispatcher {
type = "Akka.TestKit.CallingThreadDispatcherConfigurator, Akka.TestKit"
throughput = 2147483647
}
# Disable batching in order to prevent flakiness with Akka.Remote tests (since they have low message frequency)
remote.dot-netty.tcp.batching.enabled = false
}
}
Additionally, it's also possible to change the default IScheduler
implementation in the Akka.TestKit
to use a virtualized TestScheduler
implementation that Akka.NET developers can use to artificially advance time forward. To swap in the TestScheduler
, developers will want to include the HOCON below:
