mockall VS quickcheck

I use the mockall crate myself, which works rather well. It does however mean that you need to generally write your code as traits, and pass them around as traits.

Fortunately for me, there is an excellent crate Mockall maintained by angels and with the owner Alan Somers pretty active in helping the community when a question arises.

Maybe https://github.com/BurntSushi/quickcheck too?

Yeah as other have mentioned, I was using Rust before 1.0.

This is my first public commit: https://github.com/BurntSushi/quickcheck/commit/c9eb2884d6a6...

I didn't write any substantive Rust before that point. So I'm at over 9 years.

The book, Zero To Production In Rust, uses quickcheck:

Hi all! I'm looking for some feedback on my latest crate, reltester. It's a small utility crate that, when paired with property-based testing with e.g. quickcheck makes it very easy to check that your handwritten comparison trait implementations satisfy the necessary constraints (transitivity, reflexivity, and all that stuff). I wrote it our of frustration after finding many subtle bugs in our PartialEq and PartialOrd implementations at $JOB, and hopefully someone else will find it useful.

For what it's worth this would also be a good candidate for property based testing, like with: https://github.com/BurntSushi/quickcheck

I'm aware of Hypothesis and its approach, but the connection between Hypothesis and arbitrary is indeed non-obvious. Even looking over the API docs again, the most I could pick up was this on the docs of Unstructured:

Quickcheck https://github.com/BurntSushi/quickcheck

I'm running into a strange issue while using [quickcheck](https://github.com/BurntSushi/quickcheck) to implement tests and I'm hoping someone here might have an idea. Long story short, I have tests which fail in weird ways when using quickcheck that I can't reproduce otherwise, so I'm not even sure if it's a legitimate issue or not.
