Composite Tests - including ToC, Label/Refs, Credit Granting.

[xronosuf]

There are currently a number of composite tests that need to be devised/written. Some of these we've discussed, but having an array of composite tests will be helpful both for discussing repo structure, as well as making sure things like the comprehensive diff test works thoroughly.

Some composite tests that I can think of are as follows:

• A test of all the various table of contents features and organizations, I know that @bartsnapp has been working on this in general, although I don't know if he has done test file(s) yet.
• A test of all the options (and their impacts) for the ximera and/or xourse document classes.
• A test set for all the combinations of interactions between labels and reference commands - I know @wiobber is working on this and has a test file with a lot of content, although I don't know if it is complete and/or added to the current repo version.
• A test set for all elements capable of granting page credit to a student, for testing anything related to grading a student (this is less about cross dtx interaction, and more about having a single test xourse that groups together a collection that is likely to be impacted/tested together).

Feel free to reply to add other composite tests you think should be added and/or if you have written any of the ones on the current list above.
