Stefan Metzmacher 42c9e569e8 dbcheck: detect the change after deletion bug
Old versions of 'samba-tool dbcheck' could reanimate
deleted objects, when running at the same time as the
tombstone garbage collection.

When the (deleted) parent of a deleted object
(with the DISALLOW_MOVE_ON_DELETE bit in systemFlags),
is removed before the object itself, dbcheck moved
it in the LostAndFound[Config] subtree of the partition
as an originating change. That means that the object
will be in tombstone state again for 180 days on the local
DC. And other DCs fail to replicate the object as
it's already removed completely there and the replication
only gives the name and lastKnownParent attributes, because
all other attributes should already be known to the other DC.

# vim: ft=rst

This directory contains test scripts that are useful for running a
bunch of tests all at once.

There are two parts to this:

 * The test runner (selftest/selftest.pl)
 * The test formatter

selftest.pl simply outputs subunit, which can then be formatted or analyzed
by tools that understand the subunit protocol. One of these tools is
format-subunit, which is used by default as part of "make test".

Available testsuites
====================
The available testsuites are obtained from a script, usually
source{3,4}/selftest/tests.py. This script should for each testsuite output
the name of the test, the command to run and the environment that should be
provided. Use the included "plantest" function to generate the required output.

Testsuite behaviour
===================

Exit code
------------
The testsuites should exit with a non-zero exit code if at least one
test failed. Skipped tests should not influence the exit code.

Output format
-------------
Testsuites can simply use the exit code to indicate whether all of their
tests have succeeded or one or more have failed. It is also possible to
provide more granular information using the Subunit protocol.

This protocol works by writing simple messages to standard output. Any
messages that can not be interpreted by this protocol are considered comments
for the last announced test.

For a full description of the subunit protocol, see the README file in the subunit
repository at http://github.com/testing-cabal/subunit.

The following commands are Samba extensions to Subunit:

start-testsuite
~~~~~~~~~~~~~~~
start-testsuite: name

The testsuite name is used as prefix for all containing tests.

skip-testsuite
~~~~~~~~~~~~~~
skip-testsuite: name

Mark the testsuite with the specified name as skipped.

testsuite-success
~~~~~~~~~~~~~~~~~
testsuite-success: name

Indicate that the testsuite has succeeded successfully.

testsuite-fail
~~~~~~~~~~~~~~
testsuite-fail: name

Indicate that a testsuite has failed.

Environments
============
Tests often need to run against a server with particular things set up,
a "environment". This environment is provided by the test "target": Samba 3,
Samba 4 or Windows.

The environments are currently available include

 - none: No server set up, no variables set.
 - dc,s3dc: Domain controller set up. The following environment variables will
   be set:

     * USERNAME: Administrator user name
     * PASSWORD: Administrator password
     * DOMAIN: Domain name
     * REALM: Realm name
     * SERVER: DC host name
     * SERVER_IP: DC IPv4 address
     * SERVER_IPV6: DC IPv6 address
     * NETBIOSNAME: DC NetBIOS name
     * NETIOSALIAS: DC NetBIOS alias

 - member,s4member,s3member: Domain controller and member server that is joined to it set up. The
   following environment variables will be set:

     * USERNAME: Domain administrator user name
     * PASSWORD: Domain administrator password
     * DOMAIN: Domain name
     * REALM: Realm name
     * SERVER: Name of the member server

See Samba.pm, Samba3.pm and Samba4.pm for the full list.

Running tests
=============

To run all the tests use::

   make test

To run a quicker subset run::

   make quicktest

To run a specific test, use this syntax::

   make test TESTS=testname

for example::

   make test TESTS=samba4.BASE-DELETE
