Property-Based Testing with PropEr, Erlang, and Elixir: Question 6 (page 417)
Chapter 4
Question 6
I implemented property and even tried to make an example more interesting and I would like to improve my realization.
Please, explain me, how could I use the PropEr API to delete a temporary file after performing all tests? I have not yet learned to use it to fully. In EUnit tests for this there are functions like setup
and teardown
(a sort of). How is this function in PropEr implemented? Could you demonstrate the work of such functionality?
I note also that when I replaced '$call'
to call
(I would check Symbolic Calls works too and found strange behavior - symbolic calls are not called (when I run property). Please, tell me, where is my mistake. (link to Symbolic call project)
