Cannot find Chrome binary in Azure Function App (Windows) serverless environment

Question

Hello all!

I'm trying to run Selenium tests in Azure Function App (Windows). In Visual Studio, I've included chromedriver.exe to the output directory, but when I try to run the function, this error happens.

I'm guessing Google Chrome isn't installed in the temporary drives.

This article from Anthony Chu: https://dev.to/azure/running-headless-chromium-in-azure-functions-with-puppeteer-and-playwright-2fgk mentions that installing Playwright/Puppeteer during run time will also install Chromium, allowing him to run headless Chromium in Azure Functions.

How can I achieve something similar with Selenium?

@Kai Sor Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I understand that you are trying to run Selenium tests in an Azure Function App (Windows) and is encountering an error that suggests that Google Chrome is not installed in the temporary drives. You are looking for a way to install Chrome in the Azure Function App environment to run Selenium tests.

On Azure function App windows this scenario may not be supported. see here. However, it should work fine on linux (with custom image) as explained in below articles.

This article talks about Deploy Azure function with Selenium as Azure Function and How to create a Selenium web scraper in Azure Functions.

You can also follow this article which helps in installing chromium, chrome driver and selenium on top of the Azure Function base and creating Function using docker image.

Also refer this article which talks about Executing WebDriver Tests in Chrome via Azure Functions Hosted on Linux Docker Container.

Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
