Summary

This PR bumps the Tastora testing framework from an unstable pre-release commit (v0.7.6-0.20251106081541-3ec2da2f1f7f) to a stable tagged release (v0.8.0), and includes minor code quality improvements. The changes are well-executed and align with best practices for dependency management.

Detailed Review

1. Code Quality & Architecture ✅

Strengths:

• Type safety improvement: The change from *dockerclient.Client to tastoratypes.TastoraDockerClient (test/docker-e2e/docker_test.go:54) provides better abstraction and type safety
• API modernization: The update from tastoradocker.DockerSetup(t) to tastoradocker.Setup(t) (test/docker-e2e/docker_test.go:61) suggests cleaner API design
• Import cleanup: Removal of unused direct docker import (github.com/moby/moby/client) reduces coupling to implementation details
• Test structure improvement: Moving setupDockerEnvironment() out of a subtest (test/docker-e2e/upgrade_test.go:62-64) improves test reliability by ensuring setup happens before test phases run

Idiomatic Go:

• All changes follow standard Go conventions
• Proper use of testify/suite patterns
• Clean separation of concerns maintained

2. Error Handling & Resilience ✅

No changes to error handling logic. Existing patterns remain sound:

• Proper use of s.Require().NoError(err) for critical operations
• Context propagation is consistent throughout
• No new error paths introduced

3. Security 🔒

Positive changes:

• Dependency update: Moving from an unstable commit reference to a tagged release (v0.8.0) improves supply chain security and reproducibility
• Reduced direct dependencies: The removal of direct moby/moby/client import reduces attack surface
• Transitive dependency updates: Minor version bumps (e.g., github.com/consensys/gnark-crypto v0.18.0 → v0.18.1) likely include security patches

Recommendation:
Consider running go list -m all | nancy sleuth or similar vulnerability scanning tools to verify no known CVEs in the updated dependency tree.

4. Performance & Resource Efficiency ✅

No performance-impacting changes detected:

• Docker container lifecycle management unchanged
• Test timing and concurrency patterns preserved
• Resource cleanup logic intact

5. Testing & Reliability ✅✨

Improvements:

• Better test structure: Moving setupDockerEnvironment() outside the subtest (test/docker-e2e/upgrade_test.go:62) is a significant improvement. This ensures:
  • Setup failures provide clearer error messages
  • Test phases can rely on completed setup
  • Parallel test execution is safer (if enabled)

Test Coverage:

• Codecov reports all modified lines remain covered
• Minor coverage decrease (-0.06%) is unrelated to these changes (likely in other modules)

Existing test quality:
The test suite demonstrates excellent practices:

• Comprehensive upgrade testing with pre/post verification
• Health check polling with appropriate timeouts
• Transaction verification ensuring state persistence
• Clear test phase organization with descriptive subtests

6. Documentation & Developer Experience 📝

Good:

• Removal of TODO comment in go.mod shows resolution of technical debt
• Commit messages follow conventional commits format (chore:)

Suggestion for improvement:

## Overview
This PR upgrades the Tastora testing framework from an unstable pre-release to stable v0.8.0.

### Changes
- Bump `github.com/celestiaorg/tastora` from commit reference to v0.8.0 tagged release
- Update to new Tastora API (`Setup()` vs `DockerSetup()`, `TastoraDockerClient` interface)
- Improve test structure by moving setup out of subtest
- Clean up unused direct Docker client import

### Motivation
Using tagged releases improves reproducibility and supply chain security over commit references.

Specific Findings

Minor Issues / Observations

1. Go version in go.mod (test/docker-e2e/go.mod:3)

   • go 1.24.6 - Verify this is intentional. As of my knowledge cutoff (Jan 2025), Go 1.24 exists but 1.24.6 may be a future patch version. This is likely fine if you're testing against upcoming releases.

2. Dependency marker change (test/docker-e2e/go.mod:179)

   • github.com/moby/moby v28.3.3+incompatible changed from direct to indirect dependency (added // indirect comment)
   • This is correct - Tastora now properly re-exports needed Docker types, so the direct dependency is no longer needed

3. Test structure best practice (test/docker-e2e/upgrade_test.go:62)

   • ✅ Excellent improvement moving setup outside subtest. This is a best practice for suite-based tests.

Code Quality Wins

1. Type safety (test/docker-e2e/docker_test.go:54)

   - dockerClient    *dockerclient.Client
   + dockerClient    tastoratypes.TastoraDockerClient

   Using an interface type enables easier testing and reduces coupling to concrete implementations.

2. API simplification (test/docker-e2e/docker_test.go:61)

   - client, network := tastoradocker.DockerSetup(t)
   + client, network := tastoradocker.Setup(t)

   Cleaner, more idiomatic naming.

Recommendations

High Priority

• ✅ None - the changes are production-ready

Medium Priority

• Add PR description explaining the upgrade rationale
• Consider running dependency vulnerability scanning as part of CI

Low Priority

• Verify Go version 1.24.6 in go.mod is intentional or should be 1.24
• Consider documenting Tastora v0.8.0 breaking changes (if any) in commit messages for future reference

Final Assessment

Approval: ✅ Ready to Merge

This is a well-executed maintenance PR that:

• ✅ Follows Go best practices and idiomatic patterns
• ✅ Improves dependency management (commit ref → tagged release)
• ✅ Enhances type safety and API cleanliness
• ✅ Maintains test coverage
• ✅ Improves test structure reliability
• ✅ Contains no security, performance, or reliability concerns

The code quality improvements and migration to a stable Tastora release make this a valuable update. The test structure improvement (setup outside subtest) is particularly commendable.

Codecov Note: The 0.06% coverage decrease is in unrelated modules (4 misses added elsewhere) and not caused by these changes.
