Instance Constructors

1.  new TestingConfigInternal(testSequencerClientFor: Set[TestSequencerClientFor] = Set.empty, metricsFactoryType: MetricsFactoryType = External, supportAdhocMetrics: Boolean = false, initializeGlobalOpenTelemetry: Boolean = true, doNotUseCommitmentCachingFor: Set[String] = Set.empty, reinterpretationTestHookFor: (String) => () => Unit = _ => () => (), maxCommitmentSendDelayMillis: Option[NonNegativeInt] = None, sequencerTransportSeed: Option[Long] = None, participantsWithoutLapiVerification: Set[String] = Set.empty, enableInMemoryTransactionStoreForParticipants: Boolean = false, warnOnAcsCommitmentDegradation: Boolean = true)
   supportAdhocMetrics

   if true, then creating adhoc metrics is supported (conflicts with histogram redefinitions)

   initializeGlobalOpenTelemetry

   Determines whether the OpenTelemetry instance we build is set as the global OpenTelemetry instance. This is set to false during tests to prevent failures as the global OpenTelemetry instance can be initialized just once.

   doNotUseCommitmentCachingFor

   A participant whose participant.uid.identifier that matches one of these strings will be excluded from the commitment caching.

   reinterpretationTestHookFor

   Hooks allowing participants to perform actions during reinterpretation interruptions. The argument to pass is a function that takes a string as an argument and returns the hook for the corresponding member whose identifier matches the string. The hook itself is a function that takes no argument and returns Unit. The default value provides hooks that do nothing for all members. Example:

   def myHooks(identifier: String): () => Unit =
     identifier match {
       case "participant1" => () => println(s"do something special for `participant1`")
       case _ => () => println(s"no action")
     }

   See also the example in EngineComputationAbortIntegrationTest.

   maxCommitmentSendDelayMillis

   The maximum delay for sending commitments in milliseconds. If not set, commitment sending is delayed by a random amount at most the default value.

   sequencerTransportSeed

   The seed to be used for choosing threshold number of sequencer transports.

   warnOnAcsCommitmentDegradation

   When true, we log a warning when the participant falls behind in producing ACS commitments. This is the default. A false value lowers the logging level to debug, while keeping the degradation of the health status. In tests, we should set it to false, because any test with high load can cause a participant to lag behind in producing commitments, which would produce an ACS commitment degradation warning and cause a CI test to be reported as failed. Because in our testing framework any test can run colocated with any other test, any test, load-intensive or not, can issue the warning. Therefore, this parameter should be set to false in tests, unless the test expressly checks the behavior of the degradation.
