pytest-execution-timer 0.1.0

Description:

pytestexecutiontimer 0.1.0

pytest-execution-timer
A plugin to use with Pytest to measure execution time of tests.
Distinctly different from the --durations option of pytest,
this plugin measures specific pytest startup/collection phases.
Leverages pytest hooks to measure execution time of phases.

Installation
Requires:

Python 3.7 or later.
Pytest 6.2 or later.

Install the plugin with any approach for your project.
Some examples:
pip install pytest-execution-timer

poetry add --dev pytest-execution-timer

pipenv install --dev pytest-execution-timer

Or add it to your requirements.txt file.
Usage
Enable the plugin with the --execution-timer option when running pytest:
$ pytest --execution-timer
...
Durations of pytest phases in seconds (min 100ms):
0.662 pytest_runtestloop

Control the threshold (default 100ms) by passing --minimum-duration=<value in ms>:
$ pytest --execution-timer --minimum-duration=1000 # 1 second

Understanding the output
The best ay to start is to compare the difference of the pytest_runtestloop duration
and the overall duration of the test run. Example:
Durations of pytest phases in seconds (min 100ms):
0.666 pytest_runtestloop
====== 4 passed in 0.68s ======

In this example, there's not much lost between the test run and the pytest_runtestloop
meaning that the startup and collection phases are not taking too much time.
If there's a larger difference in the timings,
look to other emitted phases to understand what's taking the most time.
These can then be examined directly,
or use other tools like profilers
or import timings.
