- Minor codebase clean-up
- Slight reorganisation of examples + tests so that we don't break stuff by accident
- CI tests

Testing ReactICS

Prerequisites

BDD module: compiled (./reactics setup or make in reactics-bdd/)
SMT module: Python 3 with z3-solver and pytest installed

pip install z3-solver pytest

Running all tests

./run_tests.sh

This runs the BDD, SMT, and generator test suites in sequence.

BDD tests

bash tests/run_tests.sh

10 regression tests that run the compiled reactics-bdd/reactics binary against example .drs files and compare output to saved baselines in tests/expected/. Covers:

Parsed system printing (-P)
Reaction listing (-r)
Reachable state enumeration (-s)
RSCTLK model checking (-c) for properties f1--f4

Input files: examples/bdd/tgc.drs, examples/bdd/tgc4.drs, reactics-bdd/in/trivial.drs.

To update baselines after an intentional output change, delete the relevant file in tests/expected/ and re-run; the test will regenerate it.

SMT tests

python3 -m pytest tests/test_smt.py -v

23 pytest tests exercising the Python API directly. Organised by layer:

Data model -- ReactionSystem, concentrations, context automata, formula construction (BagDescription, rsLTL)
SmtCheckerRS -- basic reachability (no concentrations)
SmtCheckerRSC -- reachability and rsLTL model checking with concentrations (chain reaction, heat shock response)
SmtCheckerRSCParam -- parametric verification
RSC-to-RS translation -- verifying the translated system

Generator tests

7 tests that run each generator (from examples/bdd/generators/), feed the output into the BDD model checker, and verify the expected verification result (holds / does not hold).

Generators using old syntax (examples/bdd/generators/old_syntax/) are not tested this way as they are not compatible with the current parser.
