Mocking

1. The links on this page don't activate as hyperlinks...the same Travis problem as earlier? I can't select any text on this page either.

2. I don't think the Recording calls with mock section explains things properly. e.g. what is the side-effect part doing and why does function() throw an error?

3. What's going on with MagicMock() - MagicMock()? It's not clear.

• Using mocks to model test resources:
  • We could also mention that we want to mock processes that take a lot of time/resources, so that our tests are fast and cheap and can be run often
  • Will we have to replace this call to the Google API (and throughout the page) with another map API, or can we still use it (see problem in #58)?
  • (after map plot) "We can do this by mocking the request object": we're not really mocking an object; I'd say we're mocking the Google server.
• The output cell after the patching is very long and does not scroll (same as in #79). Does this have something to do with the page not displaying correctly (no clicking or selecting)?
• Testing functions that call other functions:
  • Formatting (mostly spaces around =)
  • I agree that this part is not clear. Perhaps we can say that the MagicMock is a more powerful mocking object that supports more operations?
