Quick Tip: passing parameters from Jenkins to Maven

I saw bits and pieces of information all over the internet about parameters and properties and command-line arguments, but what I was looking for I didn’t find: a simple, straightforward explanation of how to use a Paramaterized Build in Jenkins to pass arguments through to the jUnit tests that run the functional tests that I’ve built on Webdriver. So: here it is!

Step 1: Command-line via Maven to jUnit

Use the System.getProperty tor ead system properties in Java:

        remoteHost = System.getProperty("remoteHost");
    	if (remoteHost == null) remoteHost = "http://localhost:4444/wd/hub";
    	
    	browserName = System.getProperty("browserName");
    	if (browserName == null) browserName = "Internet Explorer";

And use -D to pass them with Maven:

mvn test -DbrowserName=Firefox

Voila!

Step 2: Jenkins to Maven

First make the build a paramaterized build:

Then adjust the maven build step as shown:

(Quotes are important here because of Internet Explorer)

Voila!
