Test coverage

A test coverage report is useful in determining the percentage of our code that was executed in the course of testing. Let’s install the coverage module so we can measure whether our API was adequately tested:

(venv)$ pip install coverage

Next, let’s generate a coverage report by running this command:

(venv)$ coverage run -m pytest

Here’s the result:

Figure 8.15 – Coverage report generated

Next, let’s view the report generated by the coverage run -m pytest command. We can choose to view the report on the terminal or a web page by generating an HTML report. We’ll do both.

Let’s review the report from the terminal:

(venv)$ coverage report

Here’s the result:

From the preceding report, the percentages signify the amount of code executed and interacted with. Let’s generate the HTML report...
