Note: As of release 20121220, FitNesse comes in 2 flavours:

You can also find FitNesse in the Maven Central Repository


The latest Stable build can be found on our Continuous Integration server The QA process for Edge is the same as for a release. Test pass? Ship it!


The source Code can be found on GitHub:

What's next

It really takes very little time and effort to get FitNesse running on your machine.

  1. Click on the most recent fitnesse-standalone.jar file.
    • If this is a brand new installation, just put it in some convenient empty directory.
    • If this is an update, then copy it on top of the old fitnesse(-standalone).jar in your current installation.
  2. Type java -jar fitnesse-standalone.jar
    • It will ask you to be patient as it installs or updates.
    • Your shell should respond with something like this:
          FitNesse (v20130228) Started...
           	port:              8001
           	root page: at ./FitNesseRoot
           	logger:            none
           	authenticator:     fitnesse.authentication.PromiscuousAuthenticator
           	page factory:      fitnesse.responders.PageFactory
           	page theme:        bootstrap
           	page version expiration set to 14 days.
  3. Start up a browser and go to http://localhost
  4. The main FitNesse screen should come up. That's it. You're ready to start using FitNesse.

It didn't work!

Most likely you have another web server running. Web servers default to port 80, so if another one is running on your machine you'll have to specify another port via a CommandLineOption[?]. Try this command: java -jar fitnesse-standalone.jar -p 8080

Then point your browser to http://localhost:8080

Still no? Open me up.

What to Do If You Have the Wrong Java Runtime Environment

  • Release 20160515 and later require Java 7
  • Release 20090818 and later require Java 6
  • Release 20060719 and later require Java 5

FitNesse requires version 1.7 or later of the Java Runtime Environment (JRE). If you see the messages:

C:\fitnesse>java -jar fitnesse-standalone.jar
Exception in thread "main" java.lang.NoClassDefFoundError:
        at fitnesse.FitNesse.parseCommandLine(Unknown Source)
        at fitnesse.FitNesse.main(Unknown Source)

Then you need to download and install version 1.6 or later of the JRE. Follow these steps:

  • Press a key to close the command window
  • Go to and download and install Java by following the instructions.
  • (if required) Change the PATH environment variable so that it points to the new JRE.
    • Go to the /bin folder that contains java.exe, and copy the pathname (for example, C:\Program Files\Java\j2re<version>)
    • Go to Settings>Control Panel>System>Advanced>Environment Variables>PATH>Edit
    • Paste in that same complete pathname
    • Save the PATH environment variable, and close the System control panel
    • Start FitNesse again as described above

What to do if Apache Velocity is not found

There are two builds of the FitNesse binary:

  • fitnesse.jar contains only the fitnesse code, no dependencies. This is the version you use if you're using a dependency management system like Maven or Apache Ivy.
  • fitnesse-standalone.jar is the big one-has-all jar file containing FitNesse and support libraries.

If you're seeing this:

C:\fitnesse>java -jar fitnesse.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/velocity/context/Context
        at fitnesse.FitNesseContext.(
        at fitnesse.FitNesseContext.(
        at fitnesseMain.FitNesseMain.loadContext(
        at fitnesseMain.FitNesseMain.launchFitNesse(

You probably want the latter.

Learning More

If you have not yet done so, check out the Two Minute Example. To learn more about what FitNesse acceptance testing is all about, see AcceptanceTests. If you are ready to start creating FitNesse pages and test tables, check out EditingFitNessePages[?] and CreatingTestTables[?].

Memory Issues.

When you use FitNesse extensively, some operations take more than the default memory allocated to the JVM. This can cause tests to fail for out of heap space reasons. You can fix this by adding the -Xmx100M JVM argument to the java command line when you start FitNesse. java -Xmx100M -jar fitnesse.jar.

Memory issues and the build.

If you build FitNesse from source, the ant script may fail for out of heap space reasons. You can fix this by setting the ANT_OPTS environment variable to -Xmx100M.
