cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>This is the design document for a revamped automatic testing framework.
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncThe revamp aims at replacing the current tinderbox based testing by a new
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncsystem that is written from scratch.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The old system is not easy to work with and was never meant to be used for
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmanaging tests, after all it just a simple a build manager tailored for
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccontiguous building. Modifying the existing tinderbox system to do what
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwe want would require fundamental changes that would render it useless as
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynca build manager, it would therefore end up as a fork. The amount of work
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncrequired would probably be about the same as writing a new system from
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncscratch. Other considerations, such as the license of the tinderbox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncsystem (MPL) and language it is realized in (Perl), are also in favor of
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncdoing it from scratch.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The language envisioned for the new automatic testing framework is Python. This
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncis for several reasons:</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<blockquote>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<li>Python is used quite a bit inside Sun (dunno about Oracle).</li>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<li>Works relatively well with Apache for the server side bits.</li>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<li>It is more difficult to produce write-only code in Python (alias the

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>Each testbox has a unique name corresponding to its DNS zone entry. When booted
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynca testbox script is started automatically. This script will query the test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmanager for orders and execute them. The core order downloads and executes a
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctest driver with parameters (configuration) from the server. The test driver
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncdoes all the necessary work for executing the test. In a typical VirtualBox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctest this means picking a build, installing it, configuring VMs, running the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctest VMs, collecting the results, submitting them to the server, and finally
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccleaning up afterwards.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The testbox environment which the test drivers are executed in will have a
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncnumber of environment variables for determining location of the source images
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncand other test data, scratch space, test set id, server URL, and so on and so
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>On startup, the testbox script will look for crash dumps and similar on
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncsystems where this is possible. If any sign of a crash is found, it will
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncput any dumps and reports in the upload directory and inform the test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmanager before reporting for duty. In order to generate the proper file
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncnames and report the crash in the right test set as well as prevent
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncreporting crashes unrelated to automatic testing, the testbox script will
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynckeep information (test set id, ++) in a separate scratch directory
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync(${TESTBOX_PATH_SCRATCH}/testbox) and make sure it is synced to the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncdisk (both files and directories).</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>After checking for crashes, the testbox script will clean up any previous test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwhich might be around. This involves first invoking the test script in cleanup
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmode and the wiping the scratch space.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>When reporting for duty the script will submit information about the host: OS
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncname, OS version, OS bitness, CPU vendor, total number of cores, VT-x support,
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncAMD-V support, amount of memory, amount of scratch space, and anything else that
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccan be found useful for scheduling tests or filtering test configurations.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The orders are kept in a queue on the server and the testbox script will fetch
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncthem one by one. Orders that cannot be executed at the moment will be masked in
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncthe query from the testbox.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<dd>Downloads and executes the a specified test driver with the given

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncThe server can specify more than one ZIP file to be downloaded and unpacked
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncbefore executing the test driver. The testbox script may cache these zip
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncfiles using http time stamping.</dd>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<dd>Aborts the current test driver. This will drop a hint to the driver and give
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncit 60 seconds to shut down the normal way. If that fails, the testbox script
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwill kill the driver processes (SIGKILL or equivalent), invoke the

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncof the last two steps fail in some way, the testbox will be rebooted.</dd>

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncdirectly and instead rely on generic utility methods in the test driver
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncframework. That way we can more easily reimplement the functionality of the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccore utilites and drop the dependency on them. It also allows us to quickly

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The test drivers are programs that will do the actual testing. In addition to
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncrun under the testbox script, they can be executed in the VirtualBox development
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncenvironment. This is important for bug analysis and for simplifying local
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctesting by the developers before commiting changes. It also means the test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncdrivers can be developed locally in the VirtualBox development environment.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The main difference between executing a driver under the testbox script and
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncrunning it manually is that there is no test manager in the latter case. The
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctest result reporter will not talk to the server, but report things to a local
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynclog file and/or standard out/err. When invoked manually, all the necessary

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncis for cleaning up after a reboot or aborted run. The latter is done by the

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncby itself after a normal run.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The server side will be implemented using a webserver (apache), a database
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync(postgres) and cgi scripts (Python). In addition a cron job (Python) running

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>Configuration of testboxes doesn't involve much work normally. A testbox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncis added manually to the test manager by entering the DNS entry and/or IP
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncaddress (the test manager resolves the missing one when necessary) as well as

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncinstaller). Queries from unregistered testboxes will be declined as a kind of
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncsecurity measure, the incident should be logged in the webserver log if
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncpossible. In later dealings with the client the System UUID will be the key
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncidentifier. It's permittable for the IP address to change when the testbox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncisn't online, but not while testing (just imagine live migration tests and
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncnetwork tests). Ideally, the testboxes should not change IP address.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The testbox edit function must allow changing the name and system UUID.</p>

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccapable of to filter out tests and test configurations that won't work on that
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctestbox. To examplify this take the ACP2 installation test. If the test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmanager does not make sure the testbox have VT-x or AMD-v capabilities, the test
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncis surely going to fail. Other testbox capabilities would be total number of
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncCPU cores, memory size, scratch space. These testbox capabilities should be
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccollected automatically on bootup by the testbox script together with OS name,
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncOS version and OS bitness.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>A final thought, instead of outright declining all requests from new testboxes,
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwe could record the unregistered testboxes with ip, UUID, name, os info and
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccapabilities but mark them as inactive. The test operator can then activate
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncthem on an activation page or edit the testbox or something.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>Testcases are organized into groups. A testcase can be member of more than one
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncgroup. The testcase gets a priority assigned to it in connection with the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncgroup membership.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>Testgroups are picked up by a testbox partition (aka scheduling group) and a
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncprioirty, scheduling time restriction and dependencies on other test groups are
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncassociated with the assignment. A testgroup can be used by several testbox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncpartitions.</p>

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The initial scheduler will be modelled after what we're doing already on in the

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncfor a testcase. It will schedule on a testcase level, using the combined
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncpriority of the testcase in the test group and the test group with the testbox

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync'id' + 'valid_period', where the latter is expressed using two fields
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync([effective...expire-1]). Only, how do you tell the database engine that

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynctrouble because of the time axsis and that to our knowledge foreign keys
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncmust reference exactly one row in the other table. When time is involved
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwhat we wish to tell the database is that at any given time, there actually

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>When gathering a gang of testboxes for a testcase, we do not want to wait
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncforever and have testboxes doing nothing for hours while waiting for partners.
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncSo, the gathering has a reasonable timeout (imagine something like 20-30 mins).</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>Also, we need some way of dealing with 'abort' and 'reboot' commands being

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>When changing the status to 'gang-timeout' we have to be careful. First of all,
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwe need to exclusively lock the SchedQueues and TestBoxStatuses (in that order)
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncand re-query our status. If it changed redo the checks in scenario #2 point 2.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>If we still want to timeout/abort, change the state from 'gang-gathering' to
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync'gang-gathering-timedout' on all the gang members that has gathered so far.
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncThen reset the scheduling queue record and move it to the end of the queue.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>When acting on 'gang-timeout' the TM will fail the testset in a manner similar
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncto scenario #9. No need to repeat that.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>When a testbox completes a gang scheduled test, we will have to serialize

cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>The UI needs to be able to clean up the remains of a testbox which for some
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncreason is out of action. Normal cleaning up of abandond testcases requires
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncthat the testbox signs on or asks for work, but if the testbox is dead or
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncin some way indisposed, it won't be doing any of that. So, the testbox
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncsheriff needs to have a way of cleaning up after it.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>It's basically a manual scenario #9 but with some safe guards, like checking
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncthat the box hasn't been active for the last 1-2 mins (max idle/wait time * 2).</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<dt>Note! When disabling a box that still executing the testbox script, this</dt>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<dd>cleanup isn't necessary as it will happen automatically. Also, it's
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncprobably desirable that the testbox finishes what ever it is doing first
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncbefore going dormant.</dd>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>One of the testbox sheriff's tasks is to try figure out the reason why something
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncfailed. The test manager will provide facilities for doing so from very early
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncin it's implementation.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>We need to work out some useful status reports for the early implementation.
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncLater there will be more advanced analysis tools, where for instance we can
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsynccreate graphs from selected test result values or test execution times.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>This has changed for various reasons. The current plan is to implement the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncinfrastructure (TM & testbox script) first and do a small deployment with the
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync2-5 test drivers in the Testsuite as basis. Once the bugs are worked out, we
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsyncwill convert the rest of the tests and start adding new ones.</p>
cf22150eaeeb72431bf1cf65c309a431454fb22bvboxsync<p>We just need to finally get this done, no point in doing it piecemeal by now!</p>
