 # Days 10-12 Test your code with pytest
 
-In this lesson I show you how to use pytest to test a simple guessing game. It might not be the easiest example for a beginner, but it allows me to show some real world issues you want to address in your test code.

 Next I show you some tactics to mock out user inputs and random data, because test data needs to be predictable. We also learn how we can capture/test standard output of our program. 
 
-Finally I show you some TDD or _test driven development_ in action by implementing Fizz Buzz by writing the tests first, in small incremental steps. You learn about the `pytest.mark.parametrize` decorator to elegantly handle repetitive tests.

-The pytest framework is huge and this is just a subset of features. I hope this gives you a head start though to start writing (more) tests for your programs to produce more reliable software.

 Head over to [PyBites Code Challenge 39 - Writing Tests With Pytest](https://codechalleng.es/challenges/39/) and start adding tests to your code or if you're already covered maybe you want to do that as contribution to an open source project? 
 
-By the way, notice that we use pytest for [our Bites](https://codechalleng.es/bites/) too. Under the _TESTS_ tab of each Bite you can see how your code will be tested and when you hit _Save + verify_ you can look at its output.

-Lastly if you are serious about writing tests and pytest check out Brian Okken's [Test and Code](http://testandcode.com) podcast and his [Python Testing with pytest](https://pragprog.com/book/bopytest/python-testing-with-pytest) ([our review](https://pybit.es/pytest-book.html)), which goes into much more depth.

+## Day N+2: Your Turn: Write a fixture
 
 You wrote some test code? Good, hope that felt good. I know it does because with a set of tests you have more confidence to make any changes in the future. Software systems become increasingly complex so it's paramount to have a suite of tests as your project grows to catch any regression bugs. 
 
-On the topic of more complex code, one thing I did not cover are pytest fixtures:

 > The purpose of test fixtures is to provide a fixed baseline upon which tests can reliably and repeatedly execute. pytest fixtures offer dramatic improvements over the classic xUnit style of setup/teardown functions - [pytest fixtures: explicit, modular, scalable](https://docs.pytest.org/en/latest/fixture.html)
 
-A typical example is a database app that needs to setup and tear down its state before each test. Read through and [pytest fixtures easy example](http://pythontesting.net/framework/pytest/pytest-fixtures-easy-example/) and try to find a use case for the `pytest.fixture` decorator yourself. You can do it!

Then try to find a use case for the `pytest.fixture` decorator. For example, I used it [for this small DB app](https://realpython.com/blog/python/building-a-simple-web-app-with-bottle-sqlalchemy-twitter-api/#add-tests-with-pytest) (code [here](https://github.com/pybites/pytip/blob/master/tests/test_tips.py)).
