Selenium browsers and drivers

Avrea caches the browser and driver downloads made by Selenium Manager for Chrome, Firefox, and Edge. Repeated downloads reuse the packages cache, even when each job starts with an empty Selenium cache directory.

On Avrea runners

When Package Manager Cache and Selenium Browser & Driver Cache are enabled, Avrea sets these mirrors on Linux, macOS, and Windows:

SE_CHROME_MIRROR_URL="https://cache.avrea.com:8443/selenium/chrome/"
SE_CHROMEDRIVER_MIRROR_URL="https://cache.avrea.com:8443/selenium/chromedriver/"
SE_FIREFOX_MIRROR_URL="https://cache.avrea.com:8443/selenium/firefox/"
SE_GECKODRIVER_MIRROR_URL="https://cache.avrea.com:8443/selenium/geckodriver/"
SE_EDGE_MIRROR_URL="https://cache.avrea.com:8443/selenium/edge/"
SE_MICROSOFTEDGE_MIRROR_URL="https://cache.avrea.com:8443/selenium/edge/"
SE_MSEDGE_MIRROR_URL="https://cache.avrea.com:8443/selenium/edge/"
SE_MSEDGEDRIVER_MIRROR_URL="https://cache.avrea.com:8443/selenium/msedgedriver/"

Use Selenium normally. Selenium Manager selects and downloads browsers and drivers as usual, and Avrea reuses cached downloads across jobs.

What is cached

Family	Downloads
Chrome	Chrome for Testing and ChromeDriver
Firefox	Release browser installers and GeckoDriver
Edge	Browser installers and EdgeDriver

View cache activity under Selenium · Browsers & drivers in the console.

Enable or disable

Selenium Browser & Driver Cache (cache.selenium-browsers.enabled) is enabled by default. Change it at organization or repository level under Settings in the Avrea console. Package Manager Cache (cache.packages.enabled) must also be enabled.

Disable it for a repository:

avr settings set cache.selenium-browsers.enabled false

Re-enable it:

avr settings set cache.selenium-browsers.enabled true

Reset to the inherited default:

avr settings reset cache.selenium-browsers.enabled

Repository overrides take precedence over organization settings. Changes apply to new jobs. See Managing caches.

Overrides

Workflow or step environment variables can replace the corresponding mirror. To use Selenium Manager's default Chrome endpoints for a step, clear both Chrome mirrors:

- run: python browser_test.py
  env:
    SE_CHROME_MIRROR_URL: ""
    SE_CHROMEDRIVER_MIRROR_URL: ""

Clear the Firefox pair in the same way. For Edge, clear all three browser aliases and SE_MSEDGEDRIVER_MIRROR_URL, or disable the Selenium cache setting for the repository.

Custom generic mirrors (SE_BROWSER_MIRROR_URL and SE_DRIVER_MIRROR_URL) take precedence over Avrea's mirrors. Leave them unset or empty to use Avrea's cache.

Selenium Manager CLI mirror options take precedence over this configuration. For each configuration key, a value in se-config.toml takes precedence over its environment variable. Generic mirror keys are checked before specific keys.

See Selenium Manager configuration.
