end-2-end tests for kava

These tests use kvtool to spin up a kava node configuration and then runs tests against the running network. It is a git sub-repository in this directory. If not present, you must initialize the subrepo: git submodule update --init.

Steps to run

  1. Ensure latest kvtool is installed: make update-kvtool
  2. Run the test suite: make test-e2e This will build a docker image tagged kava/kava:local that will be run by kvtool.

Note: The suite will use your locally installed kvtool if present. If not present, it will be installed. If the kvtool repo is updated, you must manually update your existing local binary: make update-kvtool

Configuration

The test suite uses env variables that can be set in .env. See that file for a complete list of options. The variables are parsed and imported into a SuiteConfig in testutil/config.go.

The variables in .env will not override variables that are already present in the environment. ie. Running E2E_INCLUDE_IBC_TESTS=false make test-e2e will disable the ibc tests regardless of how the variable is set in .env.

Chains

A testutil.Chain is the abstraction around details, query clients, & signing accounts for interacting with a network. After networks are running, a Chain is initialized & attached to the main test suite testutil.E2eTestSuite.

The primary Kava network is accessible via suite.Kava.

Details about the chains can be found here.

SigningAccounts

Each Chain wraps a map of signing clients for that network. The SigningAccount contains clients for both the Kava EVM and Cosmos-Sdk co-chains.

The methods SignAndBroadcastKavaTx and SignAndBroadcastEvmTx are used to submit transactions to the sdk and evm chains, respectively.

Creating a new account

// create an account on the Kava network, initially funded with 10 KAVA
acc := suite.Kava.NewFundedAccount("account-name", sdk.NewCoins(sdk.NewCoin("ukava", 10e6)))

// you can also access accounts by the name with which they were registered to the suite
acc := suite.Kava.GetAccount("account-name")

Funds for new accounts are distributed from the account with the mnemonic from the E2E_KAVA_FUNDED_ACCOUNT_MNEMONIC env variable. The account will be generated with HD coin type 60 & the ethsecp256k1 private key signing algorithm. The initial funding account is registered with the name "whale".

IBC tests

When IBC tests are enabled, an additional network is spun up with a different chain id & an IBC channel is opened between it and the primary Kava network.

The IBC network runs kava with a different chain id and staking denom (see runner/chain.go).

The IBC chain queriers & accounts are accessible via suite.Ibc.

IBC tests can be disabled by setting E2E_INCLUDE_IBC_TESTS to false.

Chain Upgrades

When a named upgrade handler is included in the current working repo of Kava, the e2e test suite can be configured to run all the tests on the upgraded chain. This includes the ability to add additional tests to verify and do acceptance on the post-upgrade chain.

This configuration is controlled by the following env variables:

  • E2E_INCLUDE_AUTOMATED_UPGRADE - toggles on the upgrade functionality. Must be set to true.
  • E2E_KAVA_UPGRADE_NAME - the named upgrade, likely defined in app/upgrades.go
  • E2E_KAVA_UPGRADE_HEIGHT - the height at which to run the upgrade
  • E2E_KAVA_UPGRADE_BASE_IMAGE_TAG - the kava docker image tag to base the upgrade on

When all these are set, the chain is started with the binary contained in the docker image tagged E2E_KAVA_UPGRADE_BASE_IMAGE_TAG. Then an upgrade proposal is submitted with the desired name and height. The chain runs until that height and then is shutdown due to needing the upgrade. The chain is restarted with the local repo's Kava code and the upgrade is run. Once completed, the whole test suite is run.

For a full example of how this looks, see this commit on the example/e2e-test-upgrade-handler branch.
