New Revision: 318325
URL: https://svnweb.freebsd.org/changeset/base/318325
Log:
Start writing up some basic feature tests for procstat
These tests query a running process for information related to the -b,
-c, -e, and -f flags; the -f testcase is largely stubbed out, pending
additional work to determine a good, deterministic descriptor.
Core file test support is coming soon--it requires a bit more effort
due to the fact that:
- coredumps can be disabled (kern.coredump=0).
- corefiles can be put in different directories than the current
directory, or be named something other than `<prog>.core`
(`kern.corefile`).
