Catch Unit Test Ordering

Question

I would like to use Catch to do unit testing on a C++ lib. However I need the most of the test cases to be run in an order. ie the library needs to be init in a certain way and then users logged in etc. Is there any design pattern for achieving this.

Thank in advance.

Have you tried a unit test framework? Most of them have fixtures for this sort of thing. — Collin, Mar 02 '15 at 23:31
If you need them run in a specific order, place function pointers into a vector or array. — Thomas Matthews, Mar 02 '15 at 23:42

Tests are run sequentially, just as you describe. So the simple answer is you do not have to do anything to get this functionality.

However super-long test functions, with a mix of fixture creation and asserts are considered bad form when unit testing: they become harder to maintain, and it takes longer to isolate the problem. The Catch way of tackling this issue is rather interesting, see the tutorial on Sections; I also found this presentation (video, 67 mins) by Phil Nash, where (from about 20:00 to 28:00) he explains quite clearly how sections and nested sections work.
