can you test nested functions in scala?

Question

Is there any way to test a nested function (ideally with ScalaTest)?

For example, is there a way to test g() in the below code:

def f() = {
         


        

Answer 1

You could make method private[package-name] - still breaks design a bit, but keeps it private instead of protected.

Generally I agree with the fact that one should not test private methods, but if you are maintaining poorly written code...

private[example] def g() = "a string!"

def f() = {
  g() + "– says g"
}

Now test in same package (example) could test g()
