Code review comment for lp:~jtatum/mago/gcalctool

This is a good job, thanks James.

The tests worked perfectly in Karmic, but they didn't in Jaunty probably because LDTP version in repositories is a little old. However, I think this was useful to see that just setting the view to the expected value maybe isn't enough setup for a calculation test case.

For example, let's suppose that in a test case the '=' button wasn't correctly pressed, then the following test case needs to clear the display before continuing. Otherwise, the calculation doesn't start from scratch and the expected value won't be obtained. What do you think about this small change?
