I'm running into an issue while trying to test the execution of some
external applications called from inside my models.
class OmssaPacker
def self.run_omssa_aws2ez2_unix(parameters)
system("perl /pipeline/vipdac/lib/omssa_aws2ez2_unix.pl #{parameters}")
end
end
..spec code...
describe "run omssa aws2ez2 unix" do
it "should run the perl file" do
Kernel.should_receive(:system).with(/omssa_aws2ez2_unix\.pl/).and_return(true)
OmssaPacker.run_omssa_aws2ez2_unix("file").should be_true
end
end
...spec code...
Returns:
should run the perl file
Mock 'Module' expected :system with (/omssa_aws2ez2_unix\.pl/) once,
but received it 0 times
And it also actually attempts to run the perl script, since I can see
the output in the window. If I change the code to:
def self.run_omssa_aws2ez2_unix(parameters)
%x{ perl /pipeline/vipdac/lib/omssa_aws2ez2_unix.pl #{parameters} }
end
...spec code...
describe "run omssa aws2ez2 unix" do
it "should run the perl file" do
Kernel.should_receive(:`).with(/omssa_aws2ez2_unix\.pl/).and_return(true)
OmssaPacker.run_omssa_aws2ez2_unix("file").should be_true
end
end
...spec code...
Returns:
should run the perl file
expected true, got ""Program: omssa_aws2ez2.pl ...output from perl
program about command line options..."
It seems that the attempts to mock Kernel are being ignored and it's
just running the scripts anyway. I'm guessing that I'm setting up the
mock incorrectly, but I'm not sure how.
I've also tried Kernel.stub!(:system).and_return(true) with the same results.
