"resolves operator precedence unambiguously" test tries doing two consecutive calculations without resetting the calculator. Basically, it is testing whether:
2+3_((1 + 2) * 3)==1+(2_3)
A fix would to be to require a method that resets the calculator and use that between the tests, or create a new instance of RPNCalculator before the test.
Relevant Code in rpn_calculator_spec.rb:
it "resolves operator precedence unambiguously" do
#1 2 + 3 * => (1 + 2) * 3
calculator.push(1)
calculator.push(2)
calculator.plus
calculator.push(3)
calculator.times
calculator.value.should == (1+2)*3
####
#Tom Conrad: Error here. Calculator has
#to be reset.
####
#1 2 3 * + => 1 + (2 * 3)
calculator.push(1)
calculator.push(2)
calculator.push(3)
calculator.times
calculator.plus
calculator.value.should == 1+(2*3)
end
