ErrorFilter

org.apache.pekko.testkit.ErrorFilter

final case class ErrorFilter(throwable: Class[_], source: Option[String], message: Either[String, Regex], complete: Boolean)(occurrences: Int) extends EventFilter

Filter which matches Error events, if they satisfy the given criteria:

throwable applies an upper bound on the type of exception contained in the Error event
source, if given, applies a filter on the event’s origin
message applies a filter on the event’s message (either with String.startsWith or Regex.findFirstIn().isDefined); if the message itself does not match, the match is retried with the contained Exception’s message; if both are null, the filter always matches if at the same time the Exception’s stack trace is empty (this catches JVM-omitted “fast-throw” exceptions)

If you want to match all Error events, the most efficient is to use Left("").

Java API: create an ErrorFilter

complete: whether the event’s message must match the given message string or pattern completely
message: apply this filter only to events whose message matches; do not filter on message if this is given as null
pattern: if false, the message string must start with the given string, otherwise the message argument is treated as regular expression which is matched against the message (may match only a substring to filter)
source: apply this filter only to events from the given source; do not filter on source if this is given as null
