You need to specify somehow what file each particular test case depend on, isn't it?
The source file name is recorded as during registration of each test (during statics initialization).
Then go through list of source files and execute only tests from those touched within last 10 minutes.
So essentially you looking for something like this: BOOST_AUTO_TEST_CASE( test_abc ) { .... } BOOST_TEST_CASE_CONDITION( test_abc, BOOST_TEST_CASE_FILE_DEPEND( abc.cpp, 10*60 ) ) ; We could design several different runtime conditions: file dependence, time dependency and provide API for custom users conditions. I will need to think how to implement something like this. Meanwhile if you could supply code for timestamp comparisons it'll be useful. Gennadiy
