Gut VS OpenCppCoverage

And it's extensible by plugins! I like using GUT [0] for unit tests, and it injects its own editor tab with a custom UI... which is just another Control node [1].

I forgot to add that unit testing would be great for this. There's a couple frameworks out there, I'd suggest GUT: https://github.com/bitwes/Gut/tree/godot_4.

There are some downsides. GDScript is a dynamically typed language, although you can use static typing, which is slightly more error prone. It doesn't innately support things like unit tests, either, although there's a decent unit test plugin that is in the process of being ported to Godot 4. It's a bit slower than C# for non-engine functionality as well, although you'll probably only notice if you are doing a bunch of nested loop operations (in which case you should probably refactor and try to avoid that kind of thing).

I don't know if you're aware, but you can run some programs/scripts from the command line, even of tests. Using Gut, you can run tests from the terminal :

My solution in Godot 3 was to use sub-repositories. If I wanted GUT, for example, I'd fork the repo, move the contents of the addons folder to the root of the repository (and delete any extra root files), then import my GUT fork into my project as a subrepo. This meant that the entire module was stored as a single Git reference.

You can find the GUT library here: https://github.com/bitwes/Gut

There is https://github.com/OpenCppCoverage/OpenCppCoverage, which has a visual studio extension https://github.com/OpenCppCoverage/OpenCppCoveragePlugin.

Essentially, I'm looking for a tool like OpenCppCoverage, but with the possibility to exclude arbitrary chunks of code, or, at least, specific functions. An example of this functionality can be found in this other tool, CPPCoverage, which lets you enclose chunks of code between specific lines, so that they are ignored. More concretely, in the following way:

We work with OpenCppCoverage on windows, it has support to Jenkins.

Use tools to automate/simplify things where possible. Code coverage is the obvious example - OpenCppCoverage in C++, or dotCover in C#, lets you see how much of your code your tests are actually testing (and will often highlight lines of code in red/green in VS).

i used this https://github.com/OpenCppCoverage/OpenCppCoverage . visual Studio plugin is great.
