Expression analysis in WITH caluse
Follow-up from #37
Boost.Test has a nice feature of analyzing expression in test clause essentially removing the need for specialized checks list xx_GT, xx_EQ, etc.
This allows to write check expression in a natural way but at the same time gives usable messages when check fails.
For example BOOST_TEST(sut.get_property() == "expected_value") produces message like:
test.cpp(123): error: in "test_suite/test_case": check sut.get_property() == "expected_value" has failed [not_expected != expected_value]
trompeloeils' WITH macro (or a version of it) could do similar analysis of expression to produce better failure messages.
Another thought is that when there is only one expectation set for a call, the output might be simplified to directly saying that expectation failed and why in one statement rather than split "no matching expectation" / "tried xxx" duo.
