Restructure E2Es to setup chain in SetupSuite and create channel in SetupTest #1 #6629

chatton · 2024-06-18T11:28:04Z

Description

This PR addresses the first step of the overall restructuring of E2Es to allow for multiple tests running on an individual host.

The main differences introduced in this PR are.

the SetupChainsRelayerAndChannel function has been removed. Instead, the chains get created in SetupSuite and the channels get created in SetupTest.
If any test needs to provide additional configuration options, they can override the SetupTest or SetupSuite functions as required.

Follow up PRs will handle.

refactoring the relayer configuration to watch a single channel for an individual test
deploy a relayer per test (currently we are still using one relayer)
enabling t.Parallel to enable parallel test execution.
updating our CI to execute a full test suite instead of individual tests.

shout out to @anhductn2001 for the work on the first iteration of this.

ref: #5317

I created a new file for these tests since the original channel creation options were all a v1 transfer. This was more straightforward than adding conditional logic based on which test was running in the SetupTest

maybe not the end of the world as it's a once off, I can create an issue for this but it would be nice to have a generalized way of specifying per channel options per test name. Kind of chicken and egg situation as it's happening in SetupTest

removing the name from the string as s.T().Name() is different depending on the context of the invocation. using an incrementing int will behave as expected everywhere.

looks like there are some client tests failing, definitely related will investigate these

+func (s *E2ETestSuite) SetupSuite() {


Just to be clear, this means that all tests in one suite will share the same chains, and so we must be careful that accounts are not shared across the tests to avoid account sequence mismatches, resusing balances, etc, etc.

yes that's correct! By default we are always generating addresses that won't collide by default, but we need to keep this in mind in case we end up encountering a new category of error

Yeah, I think that will help a lot with running e2e tests faster, which is a big win!

+func (s *E2ETestSuite) GetChannel() ibc.ChannelOutput {


Would it better to rename this to be more precise? Either something like GetChainAChannel or refactor it to take in chain1 and chain2 to get the channel between them? A bit more verbose, but also potentially useful in more contexts?

I guess my lens is a bit skewed with all the forwarding tests, so feel free to ignore :D

Not a bad idea to be explicit here, I think GetChainAChannel would be better.

LGTM! Really nice improvements made in this PR, love it ❤️

I think we can follow up separately with any of the next steps, would be in favour of merging this sooner than later! 🚢 🚢 🚢

Assuming this TODO is directly related to the one onGetRelayer below on this file.

What issues get caused by having a single relayer for tests running in parallel? 🤔 Just curious about the specifics

We can create an issue to follow up on this too ofc! 👍🏻

In lots of tests we don't have a relayer started at the beginning, e.g. when doing a message transfer. So another test who has started a relayer, will cause that relayer to relay packets on a different test causing assertions to fail.

I agree that this would be good to get merged sooner rather than later with follow-up issues - as long as the tests run OK :)

chatton · 2024-06-19T08:02:16Z

sorry if I wasn't clear, the plan was already to do those things in follow ups! Will merge as soon as I have passing tests for all non-wasm E2Es!
