Setting up our test environment

In the previous section, we learned the basics of testing as well as what fixtures are. We will now test the endpoints for CRUD operations as well as user authentication. To test our asynchronous APIs, we’ll be making use of httpx and installing the pytest-asyncio library to enable us to test our asynchronous API.

Install the additional libraries:

(venv)$ pip install httpx pytest-asyncio

Next, we’ll create a configuration file called pytest.ini. Add the following code to it:

[pytest]
asyncio_mode = True

The configuration file is read when pytest is run. This automatically makes pytest run all tests in asynchronous mode.

With the configuration file in place, let’s create the umbrella test file, conftest.py, which will be responsible for creating an instance of our application required by the test files. In the tests folder, create the conftest file:

(venv)$ touch tests/conftest.py

We’ll start by importing...
