Unit testing and static object issues about sanandreasunity

[in0finite]

I am aware of benefits of unit testing. But there are many singletons in the project, and migrating to other solutions would require a lot of work. So, my opinion is that one should focus on implementing features/fixing bugs, rather than on making tests.

Usually implementing tests together with features have long term benefits. Just saying. In general nobody likes doing tests until last moment, so this have to be experienced to understand. Usually implementing tests post-factum is very hard task to do though; planning upfront makes test writing semi-automatic with proper architecture. So if you don't do it from beginning it will be no fun to start now.

To tell you the truth, I have started working on this. The project is a promising one and fun, but also a big one. The code quality is gonna degrade without testing.

It also reveals code smells which translate to bugs and a lack of inner mechanics understanding by others.

The main problem with testing now is that all game objects and usual C# classes are interconnected via static singleton / functions. It is not practical (and maybe impossible sometimes) to test such code.

The first thing to do is to find a way to decouple dependencies in order to substitute them in tests. As long as Unity creates game objects this is a tricky business but there are ways I'm trying to do / researching now.

I wouldn't like to dissapoint you. But my opinion is that tests are not neccesary at this moment. We should focus on high priority stuff. Doing what you want requires changing core parts of the game, which can cause a lot of bugs.
