Is there a way to run a Busted test suite in parallel?

Question

The test suite for my Lua project is split up into multiple files inside the spec/ directory. Is there a way to ask busted to run those tests in parallel? If I call busted without any arguments it runs all the tests sequentially.

Answer 1

One thing that seems to work is to use GNU Parallel to run multiple test scripts at once.

parallel busted -o utfTerminal ::: spec/*_spec.lua

The -o utfTerminal is to tell busted to use the familiar "green circles" output instead of the simplified text output it uses when its stdout is redirected.
