"Code is read much more often than it is written." - Guido van Rossum

This is true for both production code and test code.

When you are trying to understand why a test is failing, you'll be very grateful to the test author if they've taken the care to make it readable.

David Seddon came up with 6 principles to help us write more readable tests.

We discuss these, as well as more benefits of readable tests.

David's 6 Principles of Readable Tests:

1. Profit from the work of others
2. Put naming to work
3. Show only what matters
4. Don’t repeat yourself
5. Arrange, act, assert
6. Aim high
