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

If we  test on large projects, there’s a good chance that we will  experience a frustratingly slow test suite. . Slow tests are  complex, and may take more time and effort to change than the code itself. 

We can avoid the above pitfalls by following these tips:
- Limit the number of created modules
- Keep the test simple



When we perform integration-test on our __`using`__ macros, like we did in our `Translator` tests, we have to create a module in the test to make assertions against. This is a perfect solution, but we have to be careful that too many modules can cause unnecessarily slow load times when running our tests.

We will often need to define multiple nested modules, but keep the number of modules you define to a minimum. Most times, multiple test cases can share the same module.
