Parameterized JUnit tests with non-primitive parameters?

Question

There is a nice possibility to run JUnit test with parameters where the same test method is executed multiple times with different data as described here: http://junit.org/apidocs/org/junit/runners/Parameterized.html

Unfortunately, it only seems possible to use primitive parameters or Strings, but not objects. Is there any workaround known for this?

Answer 1

The type of the data() method in the use of the @Parameters annotation is List<Object[]>, so you can put in any object.

To pass in, e.g., a Money object, your array to be converted to a list would be:

{ { new Money(26, "CHF") }, { new Money(12, "USD") } }

The constructor of the test class should take a Money object as argument then.
