Overview

Package network implements and exposes a fully operational in-process Tendermint test network that consists of at least one or potentially many validators. This test network can be used primarily for integration tests or unit test suites.

The test network utilizes SimApp as the ABCI application and uses all the modules defined in the Cosmos SDK. An in-process test network can be configured with any number of validators as well as account funds and even custom genesis state.

when creating a test network, a series of Validator objects are returned. Each Validator object has useful information such as their address and public key. A Validator will also provide its RPC, P2P, and API addresses that can be useful for integration testing. In addition, a Tendermint local RPC client is also provided which can be handy for making direct RPC calls to Tendermint.

Note, due to limitations in concurrency and the design of the RPC layer in Tendermint, only the first Validator object will have an RPC and API client exposed. Due to this exact same limitation, only a single test network can exist at a time. A caller must be certain it calls Cleanup after it no longer needs the network.

A typical testing flow might look like the following: 

type IntegrationTestSuite struct {
	suite.Suite

	cfg     testutil.Config
	network *testutil.Network
}

func (s *IntegrationTestSuite) SetupSuite() {
	s.T().Log("setting up integration test suite")

	cfg := testutil.DefaultConfig()
	cfg.NumValidators = 1

	s.cfg = cfg
	s.network = testutil.New(s.T(), cfg)

	_, err := s.network.WaitForHeight(1)
	s.Require().NoError(err)
}

func (s *IntegrationTestSuite) TearDownSuite() {
	s.T().Log("tearing down integration test suite")

	// This is important and must be called to ensure other tests can create
	// a network!
	s.network.Cleanup()
}

func (s *IntegrationTestSuite) TestQueryBalancesRequestHandlerFn() {
	val := s.network.Validators[0]
	baseURL := val.APIAddress

	// Use baseURL to make API HTTP requests or use val.RPCClient to make direct
	// Tendermint RPC calls.
	// ...
}

func TestIntegrationTestSuite(t *testing.T) {
	suite.Run(t, new(IntegrationTestSuite))
}

type Network 

type Network struct {
	T          *testing.T
	BaseDir    string
	Validators []*Validator

	Config Config
}

Network defines a local in-process testing network using SimApp. It can be configured to start any number of validators, each with its own RPC and API clients. Typically, this test network would be used in client and integration testing where user input is expected.

Note, due to Tendermint constraints in regards to RPC functionality, there may only be one test network running at a time. Thus, any caller must be sure to Cleanup after testing is finished in order to allow other tests to create networks. In addition, only the first validator will have a valid RPC and API server/client.

func NewNetwork 

func NewNetwork(t *testing.T, cfg Config) *Network

NewNetwork creates a new Network for integration tests.

func (*Network) Cleanup 

func (n *Network) Cleanup()

Cleanup removes the root testing (temporary) directory and stops both the Tendermint and API services. It allows other callers to create and start test networks. This method must be called when a test is finished, typically in a defer.

func (*Network) LatestHeight 

func (n *Network) LatestHeight() (int64, error)

LatestHeight returns the latest height of the network or an error if the query fails or no validators exist.

func (*Network) SendTx 

func (n *Network) SendTx(addr sdk.AccAddress, msgs ...sdk.Msg) (*sdk.TxResponse, error)

func (*Network) WaitForDuration 

func (n *Network) WaitForDuration(duration time.Duration) error

WaitForDuration waits for at least the duration provided in blockchain time.

func (*Network) WaitForHeight 

func (n *Network) WaitForHeight(h int64) (int64, error)

WaitForHeight performs a blocking check where it waits for a block to be committed after a given block. If that height is not reached within a timeout, an error is returned. Regardless, the latest height queried is returned.

func (*Network) WaitForHeightWithTimeout 

func (n *Network) WaitForHeightWithTimeout(h int64, t time.Duration) (int64, error)

WaitForHeightWithTimeout is the same as WaitForHeight except the caller can provide a custom timeout.

func (*Network) WaitForNextBlock 

func (n *Network) WaitForNextBlock() error

WaitForNextBlock waits for the next block to be committed, returning an error upon failure.

type Validator 

type Validator struct {
	AppConfig  *srvconfig.Config
	ClientCtx  client.Context
	Ctx        *server.Context
	Dir        string
	NodeID     string
	PubKey     cryptotypes.PubKey
	Moniker    string
	APIAddress string
	RPCAddress string
	P2PAddress string
	Address    sdk.AccAddress
	ValAddress sdk.ValAddress
	RPCClient  tmclient.Client
	// contains filtered or unexported fields
}

Validator defines an in-process Tendermint validator node. Through this object, a client can make RPC and API calls and interact with any client command or handler.
