Until this morning, code coverage for my package [GitHub - ufechner7/FLORIDyn.jl: Dynamic wind farm simulation software](https://github.com/ufechner7/FLORIDyn.jl) was displayed fine. Now it says “codecov unknown”. What could be the reason?

The tests look fine, for example this one: [Improve coverage.jl · ufechner7/FLORIDyn.jl@9c61c98 · GitHub](https://github.com/ufechner7/FLORIDyn.jl/actions/runs/16544710101/job/46790673640)

It says:

```julia-auto

      ./codecov upload-coverage --git-service github --file lcov.info --gcov-executable gcov

```

I cannot see any error mesage, the coverage file was created and uploaded succesfully. Still the web page says: “No files covered by tests were changed”.

Which is wrong.

I now create my coverage reports locally, using the following script:

```julia-auto
# Copyright (c) 2025 Uwe Fechner
# SPDX-License-Identifier: BSD-3-Clause

using Pkg

function globaldependencies()
    projectpath = Pkg.project().path
    basepath, _ = splitdir(projectpath)
    Pkg.activate()
    globaldependencies = keys(Pkg.project().dependencies)
    Pkg.activate(basepath)
    globaldependencies
end

if !("LiveServer" in globaldependencies())
    println("Installing LiveServer globally!")
    run(`julia -e 'using Pkg; Pkg.add("LiveServer")'`)
end
if !("LocalCoverage" in globaldependencies())
    println("Installing LocalCoverage globally!")
    run(`julia -e 'using Pkg; Pkg.add("LocalCoverage")'`)
end

using LocalCoverage
import LiveServer as LS

git_dir = pwd()

html_dir = tempdir()
coverage = generate_coverage("FLORIDyn"; run_test = true)
html_coverage(coverage; open = false, dir = html_dir)
LS.serve(launch_browser=true, dir=html_dir)

```

But it would be nice if it would work on the website, too.

Any idea?

It is working again. I did not change anything, perhaps just a temporal outage.

Cool! I thought it was just me
