# This test could use some explanation |
|
# Much of the development of Squib has been sample-driven. Every time I want |
|
# new syntax or feature, I write a sample, get it working, and then write |
|
# tests for boundary cases in the unit tests. |
|
# |
|
# This makes documentation much easier and example-driven. |
|
# ...but I want to use those samples for regression & integration tests too. |
|
# |
|
# The above test is a good smoke test, but it just looks for exceptions. |
|
# What this set of tests do is run the samples again, but mocking out Cairo, |
|
# Pango, RSVG, and any other dependencies. We log those API calls and store |
|
# them in a super-verbose string. We compare our runs against what happened |
|
# before. |
|
# |
|
# Thus, if we ever change anything that results in a ANY change to our |
|
# regression logs, then these tests will fail. If it's SURPRISING, then we |
|
# caught an integration bug. If it's not, just update and overwrite the logs. |
|
# |
|
# So it's understood that you should have to periodically enable the |
|
# overwrite_sample method below to store the new regression log. Just make |
|
# sure you inspect the change and make sure it makes sense with the change |
|
# you made to the samples or Squib. |
|
# FOR NOW!! These two I can't get working on Travis, so I'm disabling |
