Lol

[Carreau]

I'm guessing you are maintainer of ghostwriter ?

[Zac-HD]

Yeah, it's a CLI tool shipped with Hypothesis.

Extra suggestions from slack

Pytest (testing 1/3)
>>> def test_spam(): ... / >>> def test_eggs(): ... / $ pytest my/tests/
"Just test something. Going from zero tests to one test is an infinite improvement."
"My needs are usually simple: running a collection of test functions. I don’t take advantage of the plugins, or fixtures, or any of the other advanced features."
Hypothesis (testing 2/3)
>>> from hypothesis import given
Find more bugs with less work, by generating diverse inputs for your tests.
"It would have been impossible to implement a trustworthy autograd library without Hypothesis."
"We used to hand-craft Dataframes...  It's trivial to generate them with Hypothesis, and our coverage is now close to 90%."
"The only problem is that it's too good at finding bugs, so I can't sneak broken code in before feature freeze."
Ghostwriter (testing 3/3)
$ hypothesis write numpy.matmul / $ hypothesis write gzip.compress
Don't like writing tests, or not sure how to start using Hypothesis?  Who you gonna call?  Ghostwriter!
"Is that AI?" "Well, do if-statements and regular expressions count?"
"Sometimes, magic is just someone spending more time on something than anyone else might reasonably expect. --Teller"
