How mock with rspec with prepended SimpleCommand

[Denis]

before do
  allow_any_instance_of(Class).to receive(:call).and_return(double)
end

Failure/Error: allow_any_instance_of(Class).to receive(:call).and_return(double)
Using any_instance to stub a method (call) that has been defined on a prepended module (SimpleCommand) is not supported.

Use this

before do
  allow(Class).to receive(:call).and_return(double)
end
