feat: Testground tooling #2456

evan-forbes · 2023-09-11T07:24:32Z

Overview

This is a refactor of the celestia-app tests in test-infra. The refactor focuses on further removing boiler plate and using our existing testing utilities for devUX, but also allows for more elaborate test scenarios and data collection.

Testground requires that each node is responsible for intializing, operating, performing tests, and collecting data on itself. To do this this refactor adds a new Role interface, where we define specific roles that Plan, Execute, and Retro. The first test case makes use of the interface to define a Leader and Follower, where we can have the Leader generate all the keys, configs, genesis, etc during Plan and then publishes that data to all Followers, which use their respective configuration to start their node. After execution of the test, each Role can run arbitrary Retro logic over the data produced or collected during the test run.

The first experiment is mean to add as similar environment to mainnet as possible. We will use this as a base control case for an upcoming PR that adds the unbounded blocksize test

the test can run a 3 validator network atm, but there are still a few minor but blocking bugs left. I'll add a way to sync before the "planning" stage to handle those bugs, then we should be good write the larger tests 🤞

these are deleted in the ubounded block size iirc, but current tests support them

@rootulp do you have any clue why the ledger test is breaking? its breaking locally as well, but wasn't breaking a few commits ago

rootulp

I skipped reviewing the code in test/testground/* and instead focused on the celestia-app portions

+package testground

+const (
+	Version              uint64 = 420420420


[nit] Version could use a GoDoc that explains why this number looks crazy

+	default:

+	}


IMO this thread shouldn't block this PR and instead we should create a new issue for this.

Go doesn't have exhaustive checking (like Rust) but I don't understand why silently defaulting to an old version is preferable over a panic. I see the options as:

Current

func SquareSizeUpperBound(v uint64) int { switch v { case testground.Version: return testground.SquareSizeUpperBound // There is currently only a single square size upper bound. default: return v1.SquareSizeUpperBound }

Proposal

func SquareSizeUpperBound(v uint64) int { switch v { case testground.Version: return testground.SquareSizeUpperBound case v1.Version: return v1.SquareSizeUpperBound case v2.Version: return v2.SquareSizeUpperBound default: panic(fmt.Sprintf("unsupported version %v", v)) } }

[question] related to https://github.com/celestiaorg/celestia-app/pull/2456/files#r1417502424

why define this constant if it is never used?

we should probably do the same for v2

+	// sent and received.

+	// Retro is the last function called in a test by each node. It is
+	// responsible for collecting any data from the node and/or running any

[optional] This Go code may become stale with respect to the Role interface defined in test/testground/network.go. We may remove the code and replace with a permalink.

There's a weird bug where this test is failing consistently in ci bug not locally. It also doesn't make any sense, since it was just passing and the commit that broke it only added docs and removed an usused var

setting the default consensus params here fixes the failing test, which apparently we aren't doing doing on main! This doesn't fail on main, because we don't actually have a test that checks that the version is updated but now we do here
