# JUnit 5+ Best Practices

Write JUnit 5 tests the way they are meant to be written

## What this does

You are writing unit tests in Java and want them structured well rather than just passing.

Reach for it whenever you are adding or tidying tests.

### Top 3 things it does for you

- Turn repeated tests into data-driven ones
- Check my test style against good practice
