Adding an Assertion
So, following Cucumber’s lead, we need to create a Ruby file for our program. Let’s just create an empty Ruby file for the time being so that we can stay on the outside and get the test finished before we go on to the solution. Linux/Mac users can type this to create an empty file:
| | $ touch calc.rb |
If you’re using Windows, there is no touch command, so either just create an empty text file named calc.rb in your editor or use this little trick:
| | C:\> echo.>calc.rb |
When we run cucumber again, we should see that the second step is passing and we’re on to the final step:
| | $ cucumber --format progress |
| | ..P |
