  • The 5 principles of Unit Testing

    Libraries like JSVerify or Fast-Check offer essential tools to facilitate property-based testing.

    I tend to use anything that offers property-testing, since tests are much shorter to write and uncover lots more hidden assumptions.

    My go-to choices per language are:

    - Python: Hypothesis https://hypothesis.readthedocs.io/en/latest (also compatible with PyTest)

    - Scala: ScalaCheck https://scalacheck.org (also compatible with ScalaTest)

    - Javascript/Typescript: JSVerify https://jsverify.github.io

    - Haskell: LazySmallCheck2012 https://github.com/UoYCS-plasma/LazySmallCheck2012/blob/mast...

    - When I wrote PHP (over a decade ago) there was no decent property-based test framework, so I cobbled one together https://github.com/Warbo/php-easycheck

    All of the above use the same basic setup: tests can make universally-quantified statements (e.g. "for all (x: Int), foo(x) == foo(foo(x))"), then the framework checks that statement for a bunch of different inputs.

    Most property-checking frameworks generate data randomly (with more or less sophistication). The Haskell ecosystem is more interesting:

    - QuickCheck was one of the first property-testing frameworks, using random genrators.

    - SmallCheck came later, which enumerates data instead (e.g. testing a Float might use 0, 1, -1, 2, -2, 0.5, -0.5, etc.). That's cute, but QuickCheck tends to exercise more code paths with each input.

    - LazySmallCheck builds up test data on-demand, using Haskell's pervasive laziness. Tests are run with an error as input: if they pass, we're done; if they fail, we're done; if they trigger the error, they're run again with slightly more-defined inputs. For example, if the input is supposed to be a list, we try again with the two forms of list: empty and "cons" (the arguments to cons are both errors, to begin with). This exercises even more code paths for each input.

    - LazySmallCheck2012 is a more versatile "update" to LazySmallCheck; in particular, it's able to generate functions.

  • Property Based Testing Framework for Node
    2 projects | dev.to | 15 May 2022
    The usage of hypothesis is very intuitive and simple, and presents the concept of property-based testing perfectly. So I also wanted to find an equivalent alternative in Node. Two of them have high star ratings on Github, JSVerify with 1.6K stars and fast-check with 2.8K stars. So I took some time to study fast-check a little bit and try to get closer to my daily work.

    Systems I've used for this include https://agda.readthedocs.io/en/v2.6.0.1/getting-started/what... https://coq.inria.fr https://www.idris-lang.org and https://isabelle.in.tum.de

    An easier alternative is to try disproving the statement, by executing it on thousands of examples and seeing if any fail. That gives us less confidence than a full proof, but can still be better than traditional "there exists" tests. This is called property checking or property-based testing. Systems I've used for this include https://hypothesis.works https://hackage.haskell.org/package/QuickCheck https://scalacheck.org and https://jsverify.github.io

    Using create-react-app, you’ll run npm test which uses Jest internally. If you are dealing with a lot of data on the UI, or using TypeScript, use JSVerify for property tests. For end to end tests, Cypress is a great choice.
