Hi,
I'm trying to figure out if there is anything I could do to improve compile/link-time for tests of Boost.Geometry library. Currently, the tests follow fairly canonical approach in Boost:
1) Each .cpp file defines a single test program and all local test routines are executed from test_main()
That's your problem right there. The canonical organization is unfriendly to fast test times and I would not use it for my next library. It's better to put more tests together in the same executable, and more in the same translation unit.
Hmmm - I wouldn't be crazy about this idea. The test matrix reports pass/fail often with little other information so putting a lot of tests in to the same executable will lose information. In general I like the idea of compilation / test. I would think that longer term the approach would be to permit the the tests to run simultaneously on a multi-core system. Another idea would be to make better usage of pre-compiled headers. These are supported by both gcc and msvc. Again would require non-trivial changes in build/test infrastructure. Robert Ramey
