#126: Speed up tests --------------------------+------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Resolution: | Keywords: --------------------------+------------------------------------------------- Description changed by levill_r:

Old description:

Some tests take a very long time to execute. Main causes are:

• input image(s) are too big [[BR]] => they should be reduced

(sometimes, testing on `lena.pgm` is just too costly);

• the default, non-optimized compilation settings (`-O0 -ggdb`) produces

very inefficient code for certain algorithms [[BR]] => we should locally increase the level of optimization (e.g., `-O1` or `-O2`) for these tests, and '''document''' this in `Makefile.am` (explain why we made changes in `CXXFLAGS` for a given test).

We might want to make a list of lengthy tests here before solving this ticket.

We might want to make a list of lengthy tests here before solving this ticket. Here is a beginning, for directories `milena/tests/border` and `milena/tests/morpho`. I (Roland) roughly listed tests taking more than 1 second to complete (compile time set aside):

Comment(by levill_r):

Add figures about tests' execution times in `milena/tests/border` and `milena/tests/morpho`.
