i bought the book on a whim. Been obsessed with elixir lately and have multiple projects that i don’t feel confident in my tests

vaguely heard of “property testing” before. waht i gather it has soemthing to do with generating tests

read a little bit every night and do some learning

Monday

this book includes Elixir and Erlang side by side (nice)

a machine should generate tests

automation to keep the boring stuff away

Example

sorted_list(N) -> ?LET(L, list(N), sort(L)).
prop_merge() ->
    ?FORALL(List, list(sorted_list(pos_integer())),
    merge(List) == sort(append(List))).
    ```
