These stubs form an internally consistent data-set that is not expected to change. They are
used to test the individual components in the lifecycle with data that has expected characteristics
and can be asserted as desired.

You can change/extend these stubs, and tests should not be breaking too much, since most tests
assert using expected values from the stubs. Normally, when you try to use data from the stubs that

Then we can test that it is used.

If you have many settings that possibly change a lot, maybe in different environments, it might be useful to put them on a file and then read them from it as if they were environment variables.
