Additional Real-World Considerations Beyond the Report
Here are factors that would significantly impact deployment but aren’t typically covered in academic/project documentation:
Organisational & Cultural Barriers
| Factor | Impact |
|---|---|
| Formal methods expertise | Most developers aren’t trained in timed automata or model-based testing—steep learning curve |
| Adoption resistance | Engineers often prefer familiar tools; formal methods can feel “academic” |
| Knowledge silos | If only 1–2 people understand the UPPAAL models, it becomes a liability when they leave |
CI/CD Integration Challenges
- Pipeline integration: How does this slot into Jenkins, GitHub Actions, GitLab CI, etc.?
- Execution time: Real-time test execution doesn’t scale well for fast feedback loops
- Containerisation: Running UPPAAL/TRON in Docker/Kubernetes isn’t straightforward
- Parallelisation: No mention of running tests concurrently across nodes
Model Maintenance Burden
- Model drift: As code evolves, keeping UPPAAL models synchronised is manual and error-prone
- Versioning: How do you track model changes alongside code changes?
- Code reviews: Who reviews model correctness if few understand it?
Alternative Approaches Companies Actually Use
Most companies testing distributed systems use:
- Jepsen (industry standard for database/consensus testing)
- Chaos engineering (Netflix’s Chaos Monkey, Gremlin)
- Property-based testing (QuickCheck-style tools)
- Simulation testing (FoundationDB’s approach)
These are often simpler to adopt and have larger communities.
ROI Justification
- How many bugs does this catch vs. simpler methods?
- Does the setup time justify the coverage gained?
- Hard to measure “bugs prevented” for management buy-in
Missing Practical Details
- Alerting/reporting: How are failures communicated to the team?
- Debugging workflow: When a test fails, how do you trace back to root cause?
- Documentation: Onboarding materials for new team members?
Bottom line: The report focuses on technical feasibility. Real-world adoption fails more often on people, process, and tooling integration than on technical limitations.
