Visibility and ScalaTest Posted: May 29, 2014 3:25 AM

This should be easy.

I have a class and companion object:

class TestMe {}
object TestMe
{
private def foo()= {}
}

Note that foo() is private.

I wish to test foo() with ScalaTest, but it is marked private.

How do I make it visible?

I thought I could wrap *both* files in a package declaration, then modify my declaration of foo():

package TestBait{
class TestMe {}
object TestMe
{
private[TestBait] def foo()= {}
}
}

Then in my ScalaTest suite, I would wrap my code in the same package declaration.

Dudn't work.

There has to be a simple way to do this. If it were C++ I would make the test class a friend of the C++ class being tested.

What is the "school solution", if there is one?

Thanks

WS

Hi Eric,

If you really think that method should be private then I'd suggest you leave it private and test it with the PrivateMethodTester:
