I just tried `Coverage.LCOV.write(filepath, coverage)` does not work. Here is the complete workflow that worked for me

# Julia line coverage information in VS Code

First generate `.cov` files:

```julia
using Pkg
Pkg.test("MyPackage"; coverage=true)

```

Then

```julia
using Coverage
coverage = process_folder()
open("lcov.info", "w") do io
    LCOV.write(io, coverage)
end;

```

Finally, open a source file in VS Code and run the command “Coverage Gutters: Display Coverage” in the VS Code Command Pallet.
