How to get Selenium + chromedriver + Nightwatch working.

selenium_chromedriver_nightwatch.md

https://npm.im/selenium-standalone doesn't work with recent versions of JDK and will cause Nightwatch to explode.

selenium-standalone

• Install JDK version 8
• Add this to your shell's profile:

export JAVA_HOME=/usr/libexec/java_home -v 1.8

• Restart shell
• cd ~/Your Project
• yarn add -D selenium-standalone
• selenium-standalone install
• selenium-standalone start
• Nightwatch tests should work.

OR

java Command

Download/install the following from their websites in whatever order:

• Latest JDK
• Latest Selenium Standalone Server
• Latest chromedriver

Run this command:

java -Dwebdriver.chrome.driver=/absolute/path/to/chromedriver -jar /absolute/path/to/selenium-server-standalone-3.12.0.jar

Now your Nightwatch tests should work with Chrome.

Did you just run selenium-standalone install, or did you have to install manually? Normally it installs chromedriver for you.

Also I'm pretty sure the Java install script will handle setting JAVA_HOME for you if you use the Mac OS Preferences app.

selenium-standalone is already a dev dependency in ag.js and should be installed by yarn. You shouldn't need to install it with npm.

Sorry, added a huge OR to the instructions. Use one method or the other.

selenium-standlone lives in node_modules and makes selenium-standalone install available. selenium-standalone install will install all the drivers to their respective folders in node_modules/selenium-standalone/.selenium, but selenium-standalone doesn't work with JDK 10, so you need to make sure you're using JDK 8 (not sure if 9 works—didn't test it—but 8 works and 7 should).

If you're referring to the Java Preferences under System Preferences, then I didn't see anywhere you could tweak $JAVA_HOME in it. I did see a lot of stuff about certs and I suspect certs might be why JDK 10 wasn't working, but didn't test on an http site.

I think Java will initially handle setting $JAVA_HOME, but if you happen to install JDK 10, then install 8, I don't think it overwrites it ($ java will still refer to 10), so it's safer to instruct people to just manually do it on the chance they did install 10 before 8.

Updated to refer to yarn rather than npm (but this gist can help people other than us, so I'd like to leave in the adding part).

Dude thank you for this going through these troubles now... Miss you man!
