Is it a bad practice to have an interface to define constants?
- by FabianB
I am writing a set of junit test classes in java.
There are several constants, for example strings that I will need in different test classes.
I am thinking about an interface that defines them and every test class would implement it.
The benefits I see there are:
easy access to constants: "MY_CONSTANT" instead of "ThatClass.MY_CONSTANT"
each constant defined only once
Is this approach rather a good or bad practice? I feel like abusing the concept of interfaces a little bit.
You can answer generally about interfaces/constants, but also about unit tests if there is something special about it.
