Summary
Python 3.3 onwards can happily create namespaces for packages without an __init__.py file, but importing in Python can be difficult due to the fact that imports are relative to where Python gets executed. To solve this problem, one must append the relative parent directory to Python's in-built sys.path variable, which allows the test file to be executed from within the file's directory while still allowing the test file to be executed from the parent project directory. This allows for multiple execution points in an app that can refer to each other with relative paths.

Summary
This tutorial provides an overview of testing in Python, including the differences between automated and manual testing, unit tests and integration tests, and how to use the PyTest library to write and execute tests. It also explains the differences between unit tests and test assertions, and how to use the pyTest library to write tests for a given application. Finally, it provides a free bonus course to help developers take their Python skills to the next level.

Summary
Pytest is a package installer and test package for Python that can be installed with pip. It implements standard test discovery and can be used to keep tests separate from application code. It can also be used to run tests against an installed version of the package, or to run tests against a local copy of the package with an editable install.

Summary
Pytest is a testing framework that needs to import test modules and conftest.py files for execution. There are two import modes in Python, prepend and append, which require changing sys.path. When using these modes, users may encounter issues such as missing test module names, incorrect import paths, and incorrect import paths.
