Introduction

As a SeleniumBase user, you may have encountered the issue of download notifications appearing even when running your tests in headless mode. This can be frustrating, especially when you're trying to automate complex workflows. In this article, we'll explore the reasons behind this issue and provide a step-by-step guide on how to disable download notifications using SeleniumBase.

Understanding Download Notifications

Download notifications are a feature of Google Chrome that alerts users when a file is downloaded. While this feature is useful in a normal browsing scenario, it can be a hindrance when running automated tests. When you're running your tests in headless mode, you may not want to see these notifications, as they can interfere with your test execution.

Why Do Download Notifications Appear in Headless Mode?

There are several reasons why download notifications may appear even when running your tests in headless mode. Some of the possible reasons include:

Chrome DevTools: Chrome DevTools is a set of tools that allows developers to inspect and debug web applications. When you're running your tests in headless mode, Chrome DevTools may still be enabled, causing download notifications to appear.
Chrome Settings: Chrome settings can also cause download notifications to appear. For example, if you have the "Ask where to save each file before downloading" option enabled, you may see download notifications even in headless mode.
SeleniumBase Configuration: SeleniumBase configuration can also affect the appearance of download notifications. For example, if you're using the uc (unattended mode) option, you may still see download notifications.

Disabling Download Notifications using SeleniumBase

To disable download notifications using SeleniumBase, you can follow these steps:

Step 1: Disable Chrome DevTools

To disable Chrome DevTools, you can use the --disable-devtools flag when launching Chrome. You can do this by adding the following line to your SeleniumBase configuration:

with SB(uc=True, headless=True, xvfb=True, chrome_options=['--disable-devtools']) as sb:
    ...

Step 2: Disable Chrome Settings

To disable Chrome settings that may cause download notifications to appear, you can use the --disable-extensions flag when launching Chrome. You can do this by adding the following line to your SeleniumBase configuration:

with SB(uc=True, headless=True, xvfb=True, chrome_options=['--disable-extensions']) as sb:
    ...

Step 3: Disable Unattended Mode

To disable unattended mode, you can use the uc=False option when launching SeleniumBase. You can do this by adding the following line to your SeleniumBase configuration:

with SB(uc=False, headless=True, xvfb=True) as sb:
    ...

Step 4: Disable Download Notifications using Chrome Options

To disable download notifications using Chrome options, you can use the --disable-notifications flag when launching Chrome. You can do this by adding the following line to your SeleniumBase configuration:

with SB(uc=True, headless=True, xvfb=True, chrome_options=['--disable-notifications']) as sb:
    ...
