I haven't found a way to run, say, both TestImageWriter and TestImageDecoder and get a report for both runs combined.
I think ctest is supposed to bring you there, at least from what I remember from another project.
+1 for Lagom test coverage, it would be really to get the results for AK too.

| For lagom builds, you currently have to do the same thing manually: | ||

| 1. Enable `ENABLE_LAGOM_COVERAGE_COLLECTION` in BUild/lagom/CMakeCache.txt |
| 1. Enable `ENABLE_LAGOM_COVERAGE_COLLECTION` in BUild/lagom/CMakeCache.txt | ||
| 2. Build: `Meta/serenity.sh build lagom TestImageDecoder` | ||
| 3. Run tests: `(cd Tests/LibGfx; ../../Build/lagom/bin/TestImageDecoder)` | ||
| 4. Generate report, requires an LLVM checkout and build: |

Do we need a custom LLVM build? (That's how it sounds here)
Building with coverage already requires clang and I think it usually comes with llvm-tools which contains llvm-profdata and llvm-cov.

You need llvm-profdata and llvm-cov from somewhere, and you need to get prepare-code-coverage-artifact.py from somewhere. I suppose you don't have to have a build. I'll tweak it a bit, thanks.

I'm not actually sure if that's the best way to do this. It's based on #23333.

There's also a nightly CI bot that's supposedly creating coverage information, but it's been red for years: https://github.com/SerenityOS/serenity/actions/workflows/nightly.yml (We should fix that at some point…)
