Is there a way to mock Facter::Core::Execution.execute output in ruby?

Question

I have a custom fact in ruby that uses Facter::Core::Execution.execute to execute a system command and sets the fact to true or false based on the output of the execute command. Is there a way I could mock the output of the execute command to test it?

@maxpleaner I can use rspec or pytest – Yong zhu May 28 '20 at 19:33 — Yong zhu, May 28 '20 at 19:33

Using rspec:

expect(Facter::Core::Execution).to receive(:execute).and_return(true)
