I am writing some unit tests like the following:
def executing_a_signal
a_method(a_signal.new, a_model, a_helper);
assert_equal(new_state, a_model.state)
end
The tests work fine, but the method which runs just before the assertion to execute the logic prints various messages to the console, mainly via puts.
Is there a quick, perhaps built-in, way to suppress that output to the console? I am only interested in the final effect of the method on the model object, and for the sake of keeping the console clean basically, I was hoping to find a way to simply prevent all output to the console without re-writing or commenting out those puts statements just for my tests.
It is definitely not a critical issue, but would very much like to hear any thoughts or ideas (or workaround) on it.
I use the following snippet in tests to capture and test STDOUT
def capture_stdout(&block)
original_stdout = $stdout
$stdout = fake = StringIO.new
begin
yield
ensure
$stdout = original_stdout
end
fake.string
end
With this method, the above would become:
def executing_a_signal
capture_stdout { a_method(a_signal.new, a_model, a_helper) }
assert_equal(new_state, a_model.state)
end
