'In Corda flow tests, how to get the modularized cordapps assigned only to the respective parties?

As per the Corda coding guidelines, I have seperated out modules into contracts and workflows-common. There are workflows modules like workflows-party1, workflows-part2 etc. specific to a party. Now I want to give those workflows only to that particular node in my flow tests. How to achieve this?

The other answer is one way to achieve this, another is to use the DriverDSL (depends how you are writing your tests)

driver(DriverParameters(startNodesInProcess = false, inMemoryDB = false)) {
  val charlie = startNode(
    NodeParameters(
      providedName = CHARLIE_NAME,
      rpcUsers = listOf(rpcUser),
      // important line
      additionalCordapps = cordappsForPackages("package name")
    )
  ).getOrThrow()
  // stuff
}

Either solution works

In Corda v4, it can be achieved in this way

    private val network = MockNetwork(MockNetworkParameters(cordappsForAllNodes = listOf(
            TestCordapp.findCordapp("com.template.contracts"),
            TestCordapp.findCordapp("com.template.common")),
            networkParameters = testNetworkParameters(minimumPlatformVersion = 4),
            notarySpecs = listOf(MockNetworkNotarySpec(CordaX500Name.parse("O=Notary,L=London,C=GB")))))

    private val party1 = network.createNode(MockNodeParameters(
            additionalCordapps = listOf(TestCordapp.findCordapp("com.template.workflows.party1")),
            legalName = CordaX500Name.parse("O=Party,L=London,C=GB")))
