23 selftest - Samba test runner
29 selftest [--srcdir=DIR] [--bindir=DIR] [--exeext=EXT][--target=samba4|samba3|win|kvm] [--socket-wrapper] [--quick] [--exclude=FILE] [--include=FILE] [--one] [--prefix=prefix] [--testlist=FILE] [TESTS]
33 A simple test runner. TESTS is a regular expression with tests to run.
41 Show list of available options.
49 Built binaries directory.
57 Change directory to run tests in. Default is 'st'.
59 =item I<--target samba4|samba3|win|kvm>
61 Specify test target against which to run. Default is 'samba4'.
65 Run only a limited number of tests. Intended to run in about 30 seconds on
66 moderately recent systems.
68 =item I<--socket-wrapper>
70 Use socket wrapper library for communication with server. Only works
71 when the server is running locally.
73 Will prevent TCP and UDP ports being opened on the local host but
74 (transparently) redirects these calls to use unix domain sockets.
78 Specify a file containing a list of tests that should be skipped. Possible
79 candidates are tests that segfault the server, flip or don't end.
83 Specify a file containing a list of tests that should be run. Same format
84 as the --exclude flag.
86 Not includes specified means all tests will be run.
90 Abort as soon as one test fails.
94 Load a list of tests from the specified location.
