  name                = "acceptanceTestVirtualNetwork1"
  address_space       = ["10.0.0.0/16"]
  location            = "West US"
  resource_group_name = "${azurerm_resource_group.test.name}"
}

resource "azurerm_subnet" "test" {
  name                 = "testsubnet"
  resource_group_name  = "${azurerm_resource_group.test.name}"
  virtual_network_name = "${azurerm_virtual_network.test.name}"
  address_prefix       = "10.0.1.0/24"
