Pkg.test("HiGHS")
# HiGHS uses (N+1)/2 threads. HiGHS.jl parallelises the tests and, in
# the default setting, it may use up to 4 parallel jobs. This means
# HiGHS may attempt to start up to 2(N+1) threads and we get unhandled
# exceptions on macOS and a SIGTERM on linux. To avoid these errors,
# opt out of running the tests in parallel.
