    Great tutorial, I'm eager to set up robust unit testing in my project. One note: it's not strictly necessary to create a new assembly definition in order to use EditMode tests. As shown in the message at 5:53, EditMode tests can be placed into the "editor special folder". Any script that is placed within a directory named "Editor" will be associated with the Assembly-CSharp-Editor.dll assembly, rather than the Assembly-CSharp.dll assembly. I mention this because my project uses a third-party UI library that is not currently structured in a way to easily create a new assembly definition without massive code reorganization or cyclic dependencies. Using the "Editor" folder won't offer the compile-time improvements of splitting up code into different assemblies, but it will get you up and running with unit tests. Thanks again!

    Thanks for making these guides! Working as a Java system developer in my day job I cannot put enough emphasis on how important unit tests are once your code base starts growing past the first few thousand lines of code. You implement something new here, and something random breaks over there. With no tests, those kind of bugs are real hard to spot before launch. As many developers-in-training use your guides as a starting point, it would be great if you put some emphasis on code conventions in your examples. Using conventions like given_when_then (givenSheepInScene_whenKeyPressUp_thenSheepMovesUp) or functionName_testState_expectation (move_isUp_sheepMovesUp) will really help in the long run.

    I love how you and your alter rubber ducky ego are taking this so calmly and in an upbeat manner. I'd like to say that I speak for everyone when I say that debugging usually goes with a lot of silence and a dejected sigh at the end when the bug is finally found. Or loud expletives all the way through. It's funny how there's rarely any in between.

  • @CockroachSlidy
    @CockroachSlidy4 жыл бұрын

    Unit tests also useful for debugging. Unity runs them as regular code with all debuggers attached. You can make special tests that reproduce the bug, set breakpoints, and step through code. Saves a lot of time especially for those bugs that occur one in a blue moon.

    What I'm finding very useful is for Editor UT's that check to see if my scene has the right root objects, that child objects are set static, that they have shadows turned off.. have collision boxes etc.. Extremely useful as this stuff gets screwed up all of the time and I've been writing my own tech mechanism for this.

    Neat introduction. In other cousins areas we tend to define the atomic unit as a domain aggregate as the classes and properties that belong to that aggregate are internal to that feature. In this case, if the move code cannot exist without the player code then all you're doing is reproducing work. The higher up object wins as that is the interaction point.

I have some UnityTest, which is almost the same, except the parameters. For my normal tests I can use the [TestCase(5f,true)] attribute for e.g. TakeDamageTest(float damage, bool isAliveAfterwards) and easily test multiple scenarios with the same test. Can this be done for the [UnityTest] as well somehow?

    Great tutorial, thanks so much for posting this! :) I wonder what's happening when creating a new assembly reference object (the file you call Script, which you put in the folder containing all scripts). I have about 150 scripts, in different subfolder (_scripts is the main folder, from there I have sub-categories (folders) such as economy, weapons, enemies etc etc). When i follow your tutorial and create a new Assembly Definition (putting it in the main _scripts-folder, not in every subfolder (should i do that?)) I then loose the reference to all Unity-related namespaces such as animation rigging etc. It seems that this new Assembly Definition is screwing up the default implementation I assume Unity does automatically if nothing else is specified. Cheers and keep up the good work, you make awesome content!!
