Is it possible to call `Pkg.test` and make it capture all the output from the test process?

I’m trying something like the code below, but the tests run in a sandbox so I guess that’s why I’m unable to capture the output.

```julia
function fetch_logs(io)
    buff = Vector{UInt8}(undef, bytesavailable(io))
    readbytes!(io, buff)
    return String(buff)
end

rd, wr = redirect_stdout()
Pkg.test()
write(log_file_io, fetch_logs(rd))

```

I guess the only way to do this currently is to do something like:

```julia
run(pipeline(`julia --project=$pkgdir -e 'import Pkg; Pkg.test(test_args = ["test-args"])'`, stdout="out.txt", stderr="errs.txt"))

```
