java.lang.Object akka.testkit.Coroner
public class Coroner
The Coroner can be used to print a diagnostic report of the JVM state,
including stack traces and deadlocks. A report can be printed directly, by
calling printReport
. Alternatively, the Coroner can be asked to watch
the JVM and generate a report at a later time - unless the Coroner is cancelled
by that time.
The latter method is useful for printing diagnostics in the event that, for example, a unit test stalls and fails to cancel the Coroner in time. The Coroner will assume that the test has "died" and print a report to aid in debugging.
