Formal Verification and Testing Repository

This repository contains a collection of formal verification models and testing suites designed to improve software reliability and correctness. The projects within this repository utilize TLA+ for formal verification and Java for property-based testing.

Structure

The repository is organized into two main sections: formal_verification and testing.

Formal Verification

The formal_verification directory includes various subdirectories, each targeting different systems and concepts using TLA+:

• TLA+: Contains specific implementations for distributed systems algorithms and designs, such as Kafka's leader election, Raft consensus, and simple algorithmic examples.

  • kafka: Models focusing on leader election within Kafka.
  • raft: Contains implementations for Raft distributed consensus.
  • simple: Simple models like Dining Philosophers, Stack operations, and counter implementations.
  • strimzi: Models related to Strimzi operations, like topic lifecycle management.

• Abstract Interpretation: Contains examples in a point language demonstrating abstract interpretation concepts.

• Model Checking: A directory dedicated to examples that demonstrate model checking.

Testing

The testing directory is focused on software testing methodologies:

• Performance Testing: Contains strategies for performance testing, particularly of the uto system.
• Property Based Testing: Demonstrates the implementation of property-based testing in Java.
