Command Line

Starting with version 0.2.1, Cuke4Duke has a standalone command line. This is handy if you don’t want to use Ant or Maven.

Install

The cuke4duke command line is a gem with an executable script. To use it you must first install JRuby.

When that’s sorted, install the cuke4duke gem:

jruby -S gem install cuke4duke

Now you should be able to run cuke4duke from the command line:

cuke4duke --version
cuke4duke --help

As you see, you have the same command line options as cucumber. (Since you’re running on JRuby you also have a new option: --jars that is explained below).

Running features

Since you’re using cuke4duke you probably have some jar files that need to be on the CLASSPATH. These can be specified with the --jars option. The argument passed to the --jars option must be a directory (and not a jar file). You may specify this option several times if you have jar files scattered around. (cuke4duke will add each jar file to the $CLASSPATH ruby constant).

If you are using cuke4duke with Scala or Java you will also have compiled .class files that need to be loaded. Use --require to load these. The argument given to --require must be the top level directory of your classes (the package names shoud start right underneath it). Dynamic programming languages that are supported by cuke4duke shouldn’t have to use this option if the step definition files are under features/step_definitions.

For example, if you want to run the Java examples, try this command:

cuke4duke --jars lib --require target/test-classes features

Or the Javascript ones:

cuke4duke --jars lib features
