# end-2-end tests for kava
|
|
|
|
These tests use [`kvtool`](https://github.com/kava-labs/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`](.env). See that file for a complete list
|
|
of options. The variables are parsed and imported into a `SuiteConfig` in [`testutil/config.go`](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`.
|
|
|
|
### Running on Live Network
|
|
|
|
The end-to-end tests support being run on a live network. The primary toggle for setting up the suite to use a live network is the `E2E_RUN_KVTOOL_NETWORKS` flag. When set exactly to `false`, the configuration requires the following three environment variables:
|
|
* `E2E_KAVA_RPC_URL`
|
|
* `E2E_KAVA_GRPC_URL`
|
|
* `E2E_KAVA_EVM_RPC_URL`
|
|
* `E2E_KAVA_UPGRADE_HEIGHT` - the height at which an existing upgrade was run
|
|
|
|
See an example environment configuration with full description of all supported configurations in [`.env.live-network-example`](./.env.live-network-example). This example expects a local kvtool network to be running: `kvtool testnet bootstrap`.
|
|
|
|
When run against a live network, the suite will automatically return all the sdk funds sent to `SigningAccount`s on the chain, and will return any ERC20 balance from those accounts if the ERC20 is registered via `Chain.RegisterERC20`. The pre-deployed ERC20 that is required for the tests is registered on setup.
|
|
|
|
At this time, live-network tests do not support `E2E_INCLUDE_IBC_TESTS=true`.
|
|
|
|
`E2E_KAVA_UPGRADE_HEIGHT` is supported for an existing upgrade height, and can
|
|
be used to verify before / after upgrade state. This doesn't run automatically
|
|
any upgrades.
|
|
|
|
## `Chain`s
|
|
|
|
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](runner/chain.go#L62-84).
|
|
|
|
## `SigningAccount`s
|
|
|
|
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
|
|
```go
|
|
// 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](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`](../../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](https://hub.docker.com/r/kava/kava/tags) 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.
|
