Hello, how can I use a copy method like for data class with a non data class? I have a class that initialize a date = now() but I want to change it for a test case!

[Milan Hruban]

You would have to implement that method yourself

[iguissouma]

Any library can do that? it's just for test purpose!

[James Richardson]

You have a (hidden) dependency on a clock, then. Pass the clock (or the date/time/datetime from the clock, depends) into the constructor of the object. In the test, you can use a test clock, which gives any time you like

[Matteo Mirk]

The need for this test should make you question the design of the class under test. If the source is under your control, refactor it to accept a date parameter in the constructor; otherwise create a subclass in the test path that can set the date to the value you want and use it in your test case.

I will try to refactor the code, thx.
