Get introduced to the concept of metaprogramming. Learn how to level up your programming skills by discovering the full potential of the macro system in Elixir. Understand the ins and outs of metaprogramming at a fundamental level and write incredible libraries by doing more with less code.

Metaprogramming in Elixir

We should use **unit-testing macros** only for cases where we need to test a  tricky code generation in isolation. Over-testing macros at the unit level can lead to brittle tests because we can only test the AST generated from the macro or the string of source produced. These values can be hard to match against and are subject to change, leading to error-prone tests that are difficult to maintain.



Learn about unit-testing macros using the Translator module as an example.
