test: enable the simulator for the provider module #2005

Open p-offtermatt opened 3 days ago

p-offtermatt commented 3 days ago

Description

Closes: Part of inactive validators #1913

The simulator integration is very basic for now. I just wanted it to test for panics and basic discrepancies with the inactive validators feature.

Note that this does not seriously check any of the CCV functionality; that functionality relies on IBC and multiple chains, which are not supported in the simulator.

You can run make sim-full to check out the simulator locally.

Summary by CodeRabbit

coderabbitai[bot] commented 3 days ago

Walkthrough

The recent updates added a GitHub Actions workflow to streamline simulation testing for specific branches, introduced comprehensive simulation tests within the app/provider package, and designed invariants and randomized genesis states for the x/ccv/provider module. Additionally, validator reward logic in end-to-end tests was modified for certain chains. These changes aim to enhance testing procedures, improve simulation capabilities, and ensure the robustness of validator consensus within the application.

Changes

Files Change Summary
.github/workflows/simulation.yml Introduced a GitHub Actions workflow for running simulation tests on specific branches using Go and make sim-full.
Makefile Added a new target sim-full to run full simulation tests for the application using Go.
app/provider/app.go Refactored bankBlockedAddrs logic, added import for authsims, introduced an override module for simulations, and registered store decoders.
app/provider/sim_test.go Added simulation test functions for the application to test various operations with randomized simulations.
tests/e2e/steps_inactive_vals.go Removed reward check logic for validators alice and bob in the ChainID("provi") section.
x/ccv/provider/keeper/invariants.go Introduced functions to register and check invariants related to provider consensus validators.
x/ccv/provider/module.go Modified to import simulation logic for invariants and randomized genesis state generation in the provider module.
x/ccv/provider/simulation/genesis.go Added logic to generate random GenesisState for the provider module in simulation tests.

Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.

Great work! LGTM!

I hope we simulate provider operations in the future.

:thumbs-up: Agreed. I want to keep the scope of this PR small, since this is just focussed on helping test the inactive validators feature, but in general I agree.
