Investigate usage of 3rd party Rust test frameworks

[quapka]

The built-in test framework in Rust does have some desirable features such as test marking, test parametrization, or usage of fixtures. From a quick look around, there are several 3rd party frameworks that we could maybe use:

• rstest
• quickcheck
• proptest

@MarekMracna, this is worth looking into. For example, this test setup is something we could update.
