Imagine that you're working on a website that uses a Python backend. This website might have a backend, which can be tested directly with Pytest but that won't be enough if you'd like to ensure that the front-end behaves as expected. Preferably, you'd like to test the final product that the user sees. That means that you'd like to have a tool that can simulate a browser and can run commands on your behalf.
You can install playwright with pip.
pip install --upgrade pip
pip install playwright
However, this will only install the Python dependencies. You'll also need to install headless browsers that playwright can interact with. These can be installed via:
Be warned though. This installation can take a few minutes. If you want to speed things up you can also choose to only install a subset of the available browsers.
playwright install firefox chrome
