feat: Prepare Additional Conformity Test Scenarios (#3886) #3887

mwb-al · 2025-07-01T13:04:36Z

Description:

This PR refactors the conformity test suite (@conformity-batch-1) to improve code organization, readability, and maintainability. The main changes include:

What Was Removed

Redundant approaches for overriding Ethereum endpoints

What Was Added

New utils directory with modular utility functions:
- utils.ts - Core utility functions
- constants.ts - Test constants and configuration
- interfaces.ts - Type definitions and interfaces
- overwrites.ts - Override handling logic
- processors.ts - Test data processing functions
- validations.ts - Validation utilities
- transactions.ts - Transaction-related utilities

Why These Changes Were Made

Code Organization: Moved scattered test logic into organized, reusable modules
Improved Readability: Separated concerns into logical modules
Eliminated Redundancy: Unified the approach for handling Ethereum endpoint overrides (overwrites.ts)
Better Maintainability: Modular structure makes it easier to maintain and extend tests

Validation Types in Override Files

The /overwrites folder contains various types of test validations:

eth_blockNumber

eth_blockNumber/simple-test.io - Simple block number test with wildcard result validation

eth_call

eth_call/call-callenv.io - Contract call with environment variables, wildcard result
eth_call/call-contract.io - Basic contract call test
eth_call/call-revert-abi-error.io - Contract call with ABI error revert
eth_call/call-revert-abi-panic.io - Contract call with ABI panic revert
eth_call/call-callenv-options-eip1559.io - Contract call with EIP-1559 options, wildcard result

eth_chainId

eth_chainId/get-chain-id.io - Chain ID retrieval test

eth_createAccessList

eth_createAccessList/create-al-contract.io - Create access list for contract interaction
eth_createAccessList/create-al-value-transfer.io - Create access list for value transfer
eth_createAccessList/create-al-contract-eip1559.io - Create access list for contract with EIP-1559

eth_estimateGas

eth_estimateGas/estimate-gas-contract.io - Gas estimation for contract calls
eth_estimateGas/estimate-gas-value-transfer.io - Gas estimation for value transfers
eth_estimateGas/estimate-gas-contract-eip1559.io - Gas estimation for EIP-1559 contracts

eth_feeHistory

eth_feeHistory/fee-history.io - Fee history with wildcards for gas ratios and base fees

eth_getBalance

eth_getBalance/get-balance-blockhash.io - Balance at specific block hash
eth_getBalance/get-balance.io - Standard balance retrieval
eth_getBalance/get-balance-unknown-account.io - Balance for non-existent account

eth_getBlockByHash/get-block-by-hash.io - Block retrieval by hash

eth_getBlockByNumber

eth_getBlockByNumber/get-block-n.io - Block retrieval with multiple wildcard fields
eth_getBlockByNumber/get-finalized.io - Finalized block with hash and timestamp wildcards
eth_getBlockByNumber/get-latest.io - Latest block with dynamic fields
eth_getBlockByNumber/get-genesis.io - Genesis block with dynamic fields
eth_getBlockByNumber/get-safe.io - Safe block with wildcard result

eth_getBlockTransactionCountByNumber

eth_getBlockTransactionCountByNumber/get-genesis.io - Genesis block transaction count with wildcard

eth_getCode

eth_getCode/get-code-contract.io - Contract code retrieval
eth_getCode/get-code-empty.io - Empty contract code test

eth_getLogs

eth_getLogs/no-topics.io - Log query with invalid address parameter error
eth_getLogs/contract-addr.io - Log query with invalid topics parameter error

eth_getProof

eth_getProof/get-account-proof-blockhash.io - Account proof with unsupported method error

eth_getStorageAt

eth_getStorageAt/get-storage.io - Contract storage retrieval
eth_getStorageAt/get-storage-invalid-key.io - Invalid storage key error

eth_getTransactionByBlockHashAndIndex

eth_getTransactionByBlockHashAndIndex/get-transaction-by-block-hash-and-index.io - Transaction by block hash and index

eth_getTransactionByBlockNumberAndIndex

eth_getTransactionByBlockNumberAndIndex/get-transaction-by-block-number-and-index.io - Transaction by block number and index

eth_getTransactionByHash

eth_getTransactionByHash/get-transaction-by-hash.io - Transaction retrieval by hash

eth_getTransactionCount

eth_getTransactionCount/get-nonce.io - Account nonce retrieval

eth_getTransactionReceipt

eth_getTransactionReceipt/get-access-list.io - Transaction receipt for access list transactions
eth_getTransactionReceipt/get-blob-tx.io - Transaction receipt for blob transactions
eth_getTransactionReceipt/get-dynamic-fee.io - Transaction receipt for dynamic fee transactions
eth_getTransactionReceipt/get-legacy-contract.io - Transaction receipt for legacy contract transactions
eth_getTransactionReceipt/get-legacy-input.io - Transaction receipt for legacy input transactions
eth_getTransactionReceipt/get-legacy-receipt.io - Transaction receipt for legacy receipt transactions

eth_sendRawTransaction

eth_sendRawTransaction/send-access-list-transaction.io - Send access list transaction
eth_sendRawTransaction/send-blob-tx.io - Send blob transaction
eth_sendRawTransaction/send-dynamic-fee-access-list-transaction.io - Send dynamic fee access list transaction
eth_sendRawTransaction/send-dynamic-fee-transaction.io - Send dynamic fee transaction
eth_sendRawTransaction/send-legacy-transaction.io - Send legacy transaction

The list includes all endpoints that required modifications - even if only due to the fact that the transactions from chain.rlp are not replayed before the tests start - in order for them to pass successfully.

Seems like this file doesn't exist yet when the CI is ran and it is causing it to fial, perhaps you can load it lazily here?

+          message: error instanceof Error ? error.message : 'An unknown error occurred',
+        },

Why not return the actual error if such exists? e.g.

if (error.response?.data) { return error.response.data; }

nit: isn't this expect redundant because of the isResponseValid call from earlier?

Relying on an exact nonce here could make the test fragile in the future, maybe we could use the wildcard here as well and only verify that the response is in a valid nonce format.

Hi there, thanks for the great work!

This PR includes a large number of file changes and added lines, so it would be helpful to expand the description with more context.

Specifically:

Could you provide a summary of what was changed in the conformityTest.spec file (e.g., what was removed, what was added, and why) I see you created new files and exported functions, but you could just point this out in the description?

Also, please clarify why new tests were added—what functionality or edge cases are they covering?

It would be helpful to list the new tests briefly so reviewers can quickly understand their scope and purpose.

@mwb-al So what exactly is the purpose of the wildcard, to not actually check the values?

As noted in the description, most of these values (especially block.number, block.coinbase, difficulty/prevrandao) vary with each run and chain state. Hence, the wildcard is required to ensure the test remains valid.
