Properties

allowHibernateToManageAppSchema

val allowHibernateToManageAppSchema: Boolean = true

cordappsForAllNodes

val cordappsForAllNodes: Collection<TestCordapp>? = null

TestCordapps that will be added to each node started by the DriverDSL.

debugPortAllocation

val debugPortAllocation: PortAllocation

The port allocation strategy to use for jvm debugging. Defaults to incremental.

driverDirectory

val driverDirectory: Path

The base directory node directories go into, defaults to "build//". The node directories themselves are "//", where legalName defaults to "-" and may be specified in DriverDSL.startNode.

enableSNI

val enableSNI: Boolean = true

environmentVariables

val environmentVariables: Map<String, String>

extraCordappPackagesToScan

val ~~extraCordappPackagesToScan~~: List<String>

A List of additional cordapp packages to scan for any cordapp code, e.g. contract verification code, flows and services. The calling package is automatically included in this list. If this is not desirable then use cordappsForAllNodes instead.

inMemoryDB

val inMemoryDB: Boolean = false

Whether to use in-memory H2 for new nodes rather then on-disk (the node starts quicker, however the data is not persisted between node restarts). Has no effect if node is configured in any way to use database other than H2.

isDebug

val isDebug: Boolean = false

Indicates whether the spawned nodes should start in jdwt debug mode and have debug level logging.

jmxPolicy

val jmxPolicy: JmxPolicy

Used to specify whether to expose JMX metrics via Jolokia HHTP/JSON.

networkParameters

val networkParameters: <Error class: unknown class>

The network parameters to be used by all the nodes. NetworkParameters.notaries must be empty as notaries are defined by notarySpecs.

notaryCustomOverrides

val notaryCustomOverrides: Map<String, Any?>

Extra settings that need to be passed to the notary.

notaryHandleTimeout

val notaryHandleTimeout: Duration

Specifies how long to wait to receive a notary handle. This waiting includes waiting for the notary to start. This can save time for tests which do not need to migrate from a blank schema.

notarySpecs

val notarySpecs: List<NotarySpec>

The notaries advertised for this network. These nodes will be started automatically and will be available from DriverDSL.notaryHandles, and will be added automatically to the network parameters. Defaults to a simple validating notary.

portAllocation

val portAllocation: PortAllocation

The port allocation strategy to use for the messaging and the web server addresses. Defaults to incremental.

premigrateH2Database

val premigrateH2Database: Boolean = true

Whether to use a prebuilt H2 database schema or start from an empty schema.

startNodesInProcess

val startNodesInProcess: Boolean = false

Provides the default behaviour of whether new nodes should start inside this process or not. Note that this may be overridden in DriverDSL.startNode.

systemProperties

val systemProperties: Map<String, String>

A Map of extra system properties which will be given to each new node. Defaults to empty.

useTestClock

val useTestClock: Boolean = false

If true the test clock will be used in Node.

waitForAllNodesToFinish

val waitForAllNodesToFinish: Boolean = false

If true, the nodes will not shut down automatically after executing the code in the driver DSL block. It will wait for them to be shut down externally instead.

Functions
