Write to the timeout test log file before sleeping and flush to be sure
it is created. Move the check that the after-sleep line is not written
out to the ctest script. Rename the CheckChild test to TestSleep since
it no longer checks. Do not try to read the log file if it does not
exist.
We extend the CTestTestTimeout test to check that when a test times out
its children (grandchildren of ctest) are killed. Instead of running
the timeout executable directly, we run it through a cmake script that
redirects the timeout executable output to a file. A second test later
runs and verifies that the timeout executable was unable to complete and
write data to the log file. Only if the first inner test times out and
the second inner test passes (log is empty) does the CTestTestTimeout
test pass.
