Heroku's filesystem is both ephemeral and dyno-local. Any changes made to it are lost when the dyno restarts. More importantly at the moment, when you run something like heroku run bash
you don't connect to a running dyno. Instead, you get a separate one-off dyno.
Installing Chromium (or making any other filesystem changes) in such an environment will never affect what is available in your other dynos.
It looks like Playwright really wants to manage its own browser binaries. Your best bet might be to run playwright install
near the beginning of your script, e.g. something like this:
import subprocess
from playwright.sync_api import sync_playwright
subprocess.run(["playwright", "install"])
with sync_playwright() as playwright:
# ...
This should make sure that the required binaries are always available at runtime.

Web applications continue to evolve at an unbelievable pace, and the architecture surrounding web apps get more complicated all of the time. With the growth in complexity of the web application and the development process, web application testing also needs to keep pace with the ever-changing demands.
The speed at which tests are executed and the “dearth of smartness” in testing are the two major problems developers and testers encounter.
Playwright is a framework that I’ve always heard great things about but never had a chance to pick up until earlier this year. And since then, it’s become one of my favorite test automation frameworks to use when building a new automation project. It’s easy to set up, feature-packed, and one of the fastest, most reliable frameworks I’ve worked with.
JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
