Actually cmake's support for fail tests is richer than Boost.Build's.
Here is cmake to implement simple compile fail testing where a regex on
the error messages from the compiler must be matched for the test to pass:
This cmake reads the regex from the first line of the fail test's source
There is lots of flexibility in cmake's fail test design. You can make
tests which must compile but must fail to link. You can make tests which
must complete within a certain time period. Lots of flexibility.
ctest generates XML of all the test results. That can be merged with
JUnit XML from the individual tests easily enough. And the whole lot
sent up to CDash e.g.
where fails and successes can be drilled into, and the cause figured out.
