# Rust verification tools



This is a collection of tools/libraries to support both static

and dynamic verification of Rust programs.



We see static verification (formal verification) and dynamic verification

(testing) as two parts of the same activity and so these tools can be used for

either form of verification.



- Dynamic verification using the

  [proptest](https://github.com/AltSysrq/proptest)

  fuzzing/property testing library.



- Static verification using the

  [KLEE](http://klee.github.io/)

  symbolic execution engine.



We aim to add other backends in the near future.



In addition, [we document](https://project-oak.github.io/rust-verification-tools/about.html) how the tools we wrote work

in case you are porting a verification tool for use with Rust.

(In particular, we describe how to generate LLVM bitcode files that can

be used with LLVM-based verification tools.)



## Tools and libraries



- `verification-annotations` crate: an FFI layer for creating symbolic values in

  [KLEE](http://klee.github.io/)



- `propverify` crate:

  an implementation of the [proptest](https://github.com/AltSysrq/proptest)

  library for use with static verification tools.



- `cargo-verify`: a tool for compiling a crate and

  either verifying main/tests or for fuzzing main/tests.

  (Use the `--backend` flag to select which.)



- `compatibility-test` test crate:

  test programs that can be verified either using the original `proptest`

  library or using `propverify`.

  Used to check that proptest and propverify are compatible with each other.



## Usage



TL;DR



1. Install

   For installation with Docker, see the Usage section of [our main docs](https://project-oak.github.io/rust-verification-tools/about.html).



2. Fuzz some examples with proptest



   ```

   cd compatibility-test

   cargo test

   cd ..

   ```



   (You can also use

   `cargo-verify --backend=proptest --verbose`.)



   One test should fail – this is correct behaviour.



3. Verify some examples with propverify



   `cd verification-annotations; cargo-verify --tests`



   `cd verification-annotations; cargo-verify --tests`



   No tests should fail.



4. Read [the propverify intro](https://project-oak.github.io/rust-verification-tools/using-propverify/) for an example

   of fuzzing with `proptest` and verifying with `propverify`.



5. Read [the proptest book](https://altsysrq.github.io/proptest-book/intro.html)



6. Read the source code for the [compatibility test suite](compatibility-test/src).



   (Many of these examples are taken from or based on examples in

   [the proptest book](https://altsysrq.github.io/proptest-book/intro.html).)



There is also [some limited documentation](https://project-oak.github.io/rust-verification-tools/about.html) of how this works.

## Acknowledgements



The `propverify` crate is heavily based on the design and API of the wonderful

[proptest](https://github.com/AltSysrq/proptest)

property/fuzz-testing library.

The implementation also borrows techniques, tricks and code

from the implementation – you can learn a lot about how to write

an embedded DSL from reading the proptest code.



In turn, `proptest` was influenced by

the [Rust port of QuickCheck](https://github.com/burntsushi/quickcheck)

and

the [Hypothesis](https://hypothesis.works/) fuzzing/property testing library for Python.

(`proptest` also acknowledges `regex_generate` – but we have not yet implemented

regex strategies for this library.)



## Known limitations



This is not an officially supported Google product;

this is an early release of a research project

to enable experiments, feedback and contributions.

It is probably not useful to use on real projects at this stage

and it may change significantly in the future.



Our current goal is to make `propverify` as compatible with

`proptest` as possible but we are not there yet.

The most obvious features that are not even implemented are

support for

using regular expressions for string strategies,

the `Arbitrary` trait,

`proptest-derive`.



We would like the `propverify` library and the `cargo-verify` script

to work with as many Rust verification tools as possible

and we welcome pull requests to add support.

We expect that this will require design/interface changes.
