1. Install Pytest and configure testing
Firstly, let's install the Pytest package. Go to the File → Settings → Project → Python Interpreter → click + button → open Available Packages and type Pytest in the search field like below:
Select pytest and click Install Package.

Once the Pytest package is installed, PyCharm detects it and makes it the default project test runner. At any time you can change a test runner in the project settings. |
2. Create new test using PyCharm
For tutorial purposes let's create another test for divide function.
- From the context menu choose Go To → Test → Create New Test
- In the Create Test dialog, specify test settings.
- In the test_operations.py new test called test_divide appeared. Now you can replace the template code with your own ideas.

def test_divide():
assert divide(10, 5) == 2
assert divide(200, 1) == 200
with pytest.raises(ZeroDivisionError):
divide(1, 0) |
3. Run a test
Click the green triangle and select Run 'pytest for test_oper...' to run the test:

PyCharm automatically creates a Pytest Run configuration. |
