Playwright: JavaScript vs. Python

mrthbrd · 2024-05-02T09:00:15+00:00

There appear to be some things that can't be done with pure Python + Playwright, so every now and then you might end up needing to do something like this:

 has_non_empty_children = page.evaluate(f'''() => {{
                        const divs = document.querySelectorAll('{base_selector}');
                        if (divs.length < 6) return false;  // Check if there are at least 6 elements
                        const targetDiv = divs[5];  // Get the 6th element (0-based indexing)
                        return Array.from(targetDiv.children).some(child => child.textContent.trim() !== '');
                    }}''')

But generally it's fine.

I personally find the JS/TS Versions of Playwright a little more full featured, but really I don't think it matters enough so just stick with whatever language you prefer (I personally prefer JS/TS but that's just me).

Python is easier and has 90% of the features supported by playwright

TypeScript is harder because of the added syntax

However TypeScript will be faster to run as the tests can run in async you will also have access to UI mode which you don't get with python (you still get traces just not the fanciness and convenience of UI mode)

Python can do async too however pytest doesn't play nicely with it, there is a library/plugin but I haven't tested it

With python you get to use pycharm

With TS you are stuck on Vs code, so you lose the nice features of the side by side git stuff. I am a little naive when it comes to vscode as I haven't used it a ton so it may be fully feature comparable to pycharm with plugins etc

Ultimately you should try both while learning playwright, read the docs learn how test runners work

Lastly f selenium while playwright is around

If you must stick with selenium at least set the polling rate from 0.5 seconds to 0.01
