This PR restructures and port the block validation test suite from
Moonbeam and add the necessary infrastructure for contract-based
testing.
### Test Suites Added
**Block Validation Suite 1** (`test-block-1.ts`) - *Refactored from
original `test-block.ts`*
- T01: Validates block number increments correctly after manual block
creation
- T02: Checks block timestamps are valid and within expected bounds
- T03: Verifies complete block structure including gasLimit, difficulty,
receiptsRoot, transactionsRoot, logsBloom, and other Ethereum-compatible
fields
- T04: Confirms blocks are retrievable by hash
- T05: Confirms blocks are retrievable by number
**Block Validation Suite 2** (`test-block-2.ts`) - *New*
- T01: Verifies block number persistence across test cases
- T02: Validates parent-child block hash linkage in the chain
**Block Gas Limits Suite** (`test-block-gas.ts`) - *New*
- T01-T06: Tests all three transaction types (legacy, eip1559, eip2930)
can deploy contracts at max extrinsic gas limit, and correctly reject
transactions exceeding that limit
- T07: Deploys `BlockVariables` contract and verifies runtime gas limit
is accessible from within contract execution
**Block Genesis Suite** (`test-block-genesis.ts`) - *New*
- T01: Validates genesis block (block 0) contains correct
Ethereum-compatible structure and empty transaction/uncle lists
- T02: Confirms genesis block is retrievable by hash
### Infrastructure Additions
**Contract Deployment Helpers**
- `fetchCompiledContract`: Loads compiled Solidity artifacts with ABI
and bytecode from JSON output
- `deployCompiledContract`: Handles contract deployment with support for
legacy, EIP-1559, and EIP-2930 transaction types, including gas
parameter configuration
**Solidity Test Fixtures**
- `BlockVariables.sol`: Exposes `block.gaslimit`, `block.chainid`,
`block.number` via view functions for runtime validation
- `Fibonacci.sol`: Provides `fib2(n)` pure function for computational
gas testing
- `MultiplyBy7.sol`: Minimal pure function contract for basic deployment
testing
**Enhanced Runtime Constants**
- Added `EXTRINSIC_GAS_LIMIT` (52M), `BLOCK_WEIGHT_LIMIT` (2T),
`MAX_POV_SIZE` (10MB) for all three environments
- Constants derived from and documented against Rust runtime
configuration in `operator/runtime/*/src/lib.rs`
### Dependencies
- Added `solc@0.8.30` and supporting packages (`yargs`,
`command-exists`, `js-sha3`, `memorystream`) for local Solidity
compilation
### Description
This PR introduces the **Moonwall** end-to-end (E2E) testing framework.
The primary motivation for this is to enable the porting of existing
Mobeam tests into the `DataHaven` repository.
### Key Changes
* **Node Manual Sealing:**
* Introduced a `--sealing=manual` flag for the `datahaven-node`. When
enabled, blocks are only produced on demand via an RPC call. This is the
core mechanism that allows for deterministic tests.
* **Moonwall Framework Integration:**
* Added `@moonwall/cli` and `@moonwall/util` dependencies to the
`test/package.json`.
* A new `test/moonwall.config.json` file configures the test
environment, defining how Moonwall should launch the `datahaven-node`
with the manual sealing flag.
* Added a `moonwall:test` script to `package.json` for running the
tests.
* **CI Workflow:**
* A new reusable workflow, `.github/workflows/task-moonwall-tests.yml`,
has been created to handle the setup, execution, and reporting of
Moonwall tests.
* The main `CI.yml` now includes a `moonwall-tests` job that runs after
the `build-operator` job, ensuring it always tests the correct,
freshly-built binary.
* **Example Test Suite:**
* A new test suite, `test/datahaven/suites/dev/test-block.ts`, had been
copied from moonbeam.
### How to Run Locally
1. Navigate to the `test` directory.
2. Install dependencies: `bun install`
3. Run the tests: `bun run moonwall:test`
