Remote control a browser with selenium, in Elm!
This can be used as a testing suite or you can utilize the exposed API for adapting it to your own use case.
Since this package contains a
packages.elm-lang.org. Instead, you need to install it using npm. Do this at the root of your
Elm project, where the
elm-package.json file is:
npm install elm-webdriver
You are now ready to copy some skeleton tests into your project folder. The the files from
the templates folder and
copy them to your
tests folder in your project.
Main.elm so it looks similar to the example file
If you need to use modules from your project, make sure you also add all the dependencies from the main
webdriver-tests/elm-package.json. Remember to keep those in sync.
Install selenium webdriver
To run tests locally you need the Selenium standalone server.
.jar file from the official Selenium page
and run it like this:
java -jar selenium-server-standalone.jar
You are now ready to run your tests. In another terminal, while the standalone server is still running:
cd webdriver-tests ../node_modules/.bin/elm-webdriver
You can also filter tests by name:
../node_modules/.bin/elm-webdriver --filter "Some Test Name"
If the Selenium server complains:
WARN - Exception: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https: //github.com/mozilla/geckodriver/releases
Make sure you have the geckodriver installed, and tell Selenium where it is by setting the system property:
java -Dwebdriver.gecko.driver="<path-to-geckodriver>" -jar selenium-server-standalone.jar
