capybara-wsl

Allows you use open saved pages from WSL

Capybara's save_and_open_page and save_and_open_screenshot methods don't work properly in WSL. Capybara saves pages/screenshots, but then it tries to open them via Launchy and there are several problems with that. We don't want to mess with GUI on WSL, we just want to open them in a Windows browser. However, Capybara passes a Linux path to Launchy, which obviously wouldn't work in Windows browsers.

This gem modifies that path to include wsl$ part so that it's understandable for Windows browsers. It automatically detects your current WSL distro (since version 0.3.0).

Installation

In your Gemfile add:

gem "capybara-wsl"

Then run bundle install.

Or gem install capybara-wsl, but then running it is a bit less straightforward.

Important note

In order for it to work, you have to add $BROWSER env variable.

Example for Firefox

In your .bashrc add (notice the quotes):

export BROWSER="'/mnt/c/Program Files/Mozilla Firefox/firefox.exe'"

Usage

Simply use save_and_open_page_wsl or save_and_open_screenshot_wsl instead of their normal versions. You can use same arguments.

If you installed via gem install: Run gem which capybara-wsl in your console and copy output. Use as:

 require "copied output"
 Capybara::WSL.save_and_open_page
 Capybara::WSL.save_and_open_screenshot
