In the third week we will review what we learned about testing and pytest in the previous weeks, and we will introduce the concept of fixtures in pytest.

Let's start from reading more about the testing and pytest to review and expand what we learned in the previous weeks:

• Real Python: Effective Python thesting with pytest
  • read the content of What makes pytest so useful for a great overview of the reasons why pytest is so popular
  • read the content of Parametrization: combining test to review the concept of parametrization
• Real Python: Getting started with testing in Python
  • you can read or just skim through the content of first 2 sections in order to see the difference between unittest and pytest

Fixtures are a powerful feature of pytest that allows you to define a set of data that you can reuse across multiple tests. Fixtures are especially useful when you need to set up some data before running a test and clean up after the test is done.

You should read more from Real Python: Effective Python thesting with pytest to learn more about fixtures.

In the week3 branch you will find a new directory week3 that will be used as a working directory for this week. The file week3/personal_info.py contains functions to extract important information from the dictionary with personal information.

1. Create a new file week3/test_personal_info.py and write a test for the function get_address
2. Create a ficture personal_info that can be used in the test file

• create a new file week3/conftest.py and define a fixture personal_info
• modify the test to use the fixture

3. Create a new test for the function get_name that will use the same fixture
4. Think if you could parametrize the fixture to test multiple cases

Last time we learned about parametrization of the testing functions when using pytest. You can also parametrize fixtures to test multiple cases.

• read more about parametrizing fixtures in the pytest documentation

Use the mark.parametrize to parametrize the fixture personal_info from the Exercise 1.
