Question

I have an assignment to code several methods in Scala. The methods will be encapsulated in an object that has no main method. The professor gave us a JAR file that contains an interface (my object implements this interface) as well as a sort of pseudo test object that performs various assert statements against each of my functions. This object also does not contain a main method.

Now in Intellij I simply had to declare the dependency on the JAR in the classpath, and it runs fine. Eclipse is giving me trouble though because when I go to define a Scala application run configuration it specifically asks me to name the class that contains a main method, and there is no main method.

I am assuming that I might be choosing the wrong project type for this type of set up, but I am inexperienced with this and I would appreciate any advice you might have for running something like this in eclipse.

Thanks.

Answer 1

I would either:

1. just write an object with a main method which calls the test object, or

2. start a Scala interpreter in your project (from context menu, under Scala).

Preferring the first approach, because it’s faster to repeat tests after a modification.
