refactor(e2e): extract shared test helpers to DockerTestSuite #3017
Conversation
Extract common EVM test infrastructure to reusable helpers: - RethSetup struct and SetupRethNode() for Reth node setup - SetupCelestiaAndDABridge() returns DA address - WaitForEVMHealthy() for evmsingle health checks - SetupEthClient() creates and verifies eth client - WaitForTxIncluded() waits for transaction inclusion Refactor EVMSingleUpgradeTestSuite to use the shared helpers, reducing code duplication and enabling future test reuse.

Claude finished @chatton's task in 2m 12s —— View job Code Review Complete ✅This is an excellent refactoring that successfully extracts common Docker E2E test infrastructure into reusable helpers. The changes reduce code duplication, improve maintainability, and set up a solid foundation for future tests. 🎯 Overall AssessmentStrengths:
Impact: This refactoring will significantly benefit future test development by providing ready-to-use infrastructure components. 📋 Detailed Review1. Code Quality & Architecture ✅Well-Structured Helpers:
Good Design Choices:
2. Error Handling & Resilience ✅Timeout Handling:
Network Reliability:
Considerations:
3. Resource Management & Cleanup 🔍Observation - Resource Lifecycle:
Recommendation: Consider documenting the cleanup strategy, especially for future test authors. For example, in // DockerTestSuite provides shared test infrastructure for Docker E2E tests.
// Resources created by helper methods are automatically cleaned up by the
// suite teardown or the tastora framework.
type DockerTestSuite struct {
// ...
}4. Testing Patterns ✅Excellent Test Organization:
Helper Composition: s.daAddress = s.SetupCelestiaAndDABridge(ctx) // Clear intent
s.reth = s.SetupRethNode(ctx) // Clean abstraction5. Performance & Concurrency ✅Efficient Polling:
No Concurrency Issues:
6. Documentation & Developer Experience ✅Good Documentation:
Minor Enhancement Opportunity: // SetupRethNode creates and starts a Reth node, waits for it to be ready,
// and returns connection details. Fails the test if the node doesn't start
// within 60 seconds.
func (s *DockerTestSuite) SetupRethNode(ctx context.Context) RethSetup {7. Security Considerations ✅No Security Issues Detected:

Code Review
This pull request effectively refactors common test helper functionality into the DockerTestSuite, which significantly cleans up the EVMSingleUpgradeTestSuite and improves code reuse. The extraction of setup logic for Reth, Celestia, and DA bridges into shared helpers is well-executed. I have one minor suggestion to improve error handling in one of the new helper functions.
| req, _ := http.NewRequestWithContext(ctx, http.MethodGet, healthURL, nil) | ||
| resp, err := http.DefaultClient.Do(req) | ||
| if err != nil { | ||
| return false | ||
| } | ||
| defer resp.Body.Close() | ||
| return resp.StatusCode == http.StatusOK |

It's good practice to handle all errors, even those that seem unlikely. The error from http.NewRequestWithContext is currently ignored. Checking it would make the code more robust. The suggested change also renames an error variable to avoid a redeclaration conflict that would arise from handling this new error.
req, reqErr := http.NewRequestWithContext(ctx, http.MethodGet, healthURL, nil)
if reqErr != nil {
return false
}
resp, err := http.DefaultClient.Do(req)
if err != nil {
return false
}
defer resp.Body.Close()
return resp.StatusCode == http.StatusOK
