How programmers make sure that their software is correct

For Erlang and Elixir I recommend https://propertesting.com/ book and the PropEr test framework https://github.com/proper-testing/proper.
As an example, here is the use of an advanced feature called targeted property based testing: https://proper-testing.github.io/tutorials/PropEr_testing_wi... used to test a labyrinth.
