I had a really long-running test suite and wanted to keep tabs on it remotely. I built this and paired it with a custom rspec test runner so I could follow along with the progress on my phone.

It supports updating the progress absolutely (“we are now 43% done”) and incrementally (“another unit of work is completed”). The second option there allowed me to use it even when running my tests across multiple processes. The individual test processes did not need any knowledge of the others, they just report on the work they do.
