Subject: [PATCH] Add k5test expected_msg, expected_trace
|
|
|
|
In k5test.py, add the optional keyword argument "expected_msg" to
|
|
methods that run commands, to make it easier to look for substrings in
|
|
the command output. Add the optional keyword "expected_trace" to run
|
|
the command with KRB5_TRACE enabled and look for an ordered series of
|
|
substrings in the trace output.
|
|
|
|
(cherry picked from commit 8bb5fce69a4aa6c3082fa7def66a93974e10e17a)
