refactor: integration tests #1223

0xClandestine · 2025-03-06T19:18:28Z

Motivation:

This PR refactors the integration test framework to improve performance, maintainability, and organization. The existing integration test structure had grown complex with multiple responsibilities mixed in different files, making it harder to understand and maintain. The goal is to create a more modular, better organized test framework with clear separation of concerns to make writing and maintaining integration tests easier.

Modifications:

Created two new utility files to better organize the codebase:
- IntegrationGetters.t.sol: Centralizes all state-fetching functionality, providing methods to get both current and previous state snapshots.
- IntegrationUtils.t.sol: Contains helper functions for creating users, generating allocation parameters, and other common tasks.
Restructured folder organization:
- Moved deprecated interfaces from deprecatedInterfaces/ to deprecated/.
- Relocated utility files from integration to /test/utils/ folder.
- Moved mocks from integration/mocks/ to test/mocks/.
Renamed test files to follow a more consistent naming convention:
- e.g., ALM_RegisterAndModify.t.sol → Deposit_Delegate_Modify.t.sol.
Refactored the TimeMachine.t.sol contract with improved functionality and moved it to utils/ folder to make it accessible beyond integration tests.
Added a new Constants.t.sol file to centralize commonly used constants.
Added a FOUNDRY_FUZZ_SEED to fork tests that updates weekly (this significantly reduces our RPC usage).
Moved _init into setUp() (this means setup happens once per fuzz run, rather than once per test).
Sort strategies array once, rather than JIT (sorting an array in place is time intensive).
Refactored randomness sourcing to use Vm.

Previously, we were using a uint24 _random variable combined with hashing to generate subsequent random values.
While this pattern simplified test reruns (allowing the reuse of the same _random value for consistency), it has notable drawbacks. Randomness isn't unevenly distributed, leading to modulo bias, and the process is computationally expensive.

Additionally, the same functionality can now be easily achieved through Foundry flags.

Result:

After these changes, the integration test framework will be more modular with clear separation of concerns, making it easier to understand and maintain.

Integration CI times has decreased from 15-25mins -> 5-6mins.

NOTE: There's still quite a bit that could be done, don't want this PR getting too big.

+        if (initTokenBalances[0] < 64 ether) {
+            initTokenBalances[0] = 64 ether;


nit: I think this should be initTokenBalances[0] = initTokenBalances[0] + 64 ether

-        IAllocationManagerTypes.SlashingParams memory slashingParams;
-        uint wadToSlash = _randWadToSlash();
-        slashingParams = avs.slashOperator(operator, operatorSet.id, strategies, wadToSlash.toArrayU256());
+        SlashingParams memory slashingParams = _genSlashing_Half(operator, operatorSet);


I think _randWadToSlash() still has a place in some of these tests - I caught issues using it that I wouldn't have found with a flat half slash

Plan to revamp src/utils/Random.t.sol and use it for more varied randomness. I don't think we should be slashing by half anywhere really, originally we were using _randWadToSlash everywhere. Agree it provides better coverage.

Confused why we had to use a half slashing to get this test to pass with the new framework

Wanted to remove the single use of _randWadToSlash, could use _genSlashing_Rand instead.

Bump, we should use the random slash instead of half

Where are we sourcing the randomness from?

We now source randomness from Foundry using cheats.randomUint(). The main reason we initially used the hash-based approach was to ensure test rerun-ability. For example, you could retrieve the uint24 randomness value from a failed test run and rerun the test with that fixed value. However, Foundry already supports this exact functionality through flags available for forge t (see --rerun --fuzz-seed etc.).

Also worth noting our original randomness had modulo bias.

Removed cache/ from .gitignore, the last failing fuzz seed will always be added to cache/fuzz/failures. You can re-run failed tests using that seed with --fuzz-seed.

Can we add this process of using --fuzz-seed to the ReadME?

**Motivation:** We want to support Zeus config parsing to enable testing of queued deployments. Our original deployment parser lacked the flexibility needed to support Zeus without requiring changes to Zeus itself. Additionally, the `User` and `AVS` contracts deployed by the `IntegrationDeployer` aren't able to properly read config from `IntegrationDeployer` leading to bandaid solutions. **Modifications:** - Removed `InitialDeploymentParser`: About 1k lines -> 100 for parsing. - Added `ConfigParser`: A parser that supports both fast TOML parsing and Zeus-style parsing. - Added `ConfigGetters`: A abstraction that allows contracts deployed by the `IntegrationDeployer` to easily access the current configuration. **Result:** Contracts deployed through the `IntegrationDeployer` can now reliably access their configuration, and Zeus integration is possible without needing to modify Zeus.

Any reason this is updated?

Some test is writing to this file, I fixed it. Will reset this file.
