As suite.conf and scenarios need to match 1-to-1 in lists, it's important to
extend the dictionaries by replicating the objects with a 'times' values
higher than 1 in order to match the objects correctly.
Since dictionanries are expanded at combine time, there's no need to
expand them during reserve() time because they are already expanded.
As a result, this commit reworks the kind of schema applied in each
place (and takes the change to start validating scenario files, which
were neglected previously).
Two unit tests are added as a show case. Unfortunately output showing
scenario dictionaries needs to be ignored while verifying because it was
encountered that different versions of python print dictionary elements
in different order.

In commit 329b6f4 pcu-socket path was moved to run inside the test run
dir to avoid issues between different tests creating a socket in the
same place.
However, it seems unix sockets paths are limited to 108 bytes (with Null
char included). In some cases, the run dir for a test can be quite long,
as it contains suite name, test name, etc. and the path can be longer
that the limit defined above.
In order to fix this issue, create a tmp dir using mkdtemp to ensure the
path to be used for the pcu-socket doesn't collide between different
instances of osmo-bts-trx.
Clean up of tmp dir and pcu socket is done inside the cleanup() method
called by suite.py.
method pcu_socket_path() is added to help with new implementation, and
it will be used as well as a public API later soon to be used by OsmoPcu
classes.

In commit 6100b629e5 I assumed esme
already had a cleanup function, which doesn't seem to be the case. This
means if a test calls esme.connect() and fails afterwards without
calling esme.disconnect(), the connection will be kept but as the test
will finish and the NITB is closed, then the connection will be kept
forever in an erroneous state. With the cleanup function we ensure we
will close the connection after the test.

Let's accept that during cleanup time some stuff may not be in a good
state, specially in case of a failure, but let's keep harder to clean
up everything as much as possible.
This should fix an issue in which after a test failure using an esme object,
an smpp connection is kept in a buggy state and never removed/cleaned up, and
makes all tests after it fail too because the conn is triggered at
poll() time:

As defined in [1], the different related actors are implemented in this
commit: ESME and SMSC.
SMSC: In Osmocom, the SMSC is currently implemented inside the NITB or
the MSC. A new Smsc abstract class is created to shared code between the
NITB and the MSC, and also makes it easier for later when the SMSC is
splitted. ESMEs can be dynamically added to its configuration in a
similar way to how the BTSs are added.
ESME: A new class Esme is created which can be used by tests to control
an ESME to interact with the SMSC. The ESME functionalities are
implemented using python-smpplib. Required version of this library is at
least 43cc6f819ec76b2c0a9d36d1d439308634716227, which contains support
for python 3 and some required features to poll the socket.
This commit already contains a few tests which checks different
features and tests the API. Extending tested features or scenarios can be
later done quite easily.
The tests are not enabled by default right now, because there are several
of them in a suite and the ip_address resources are not freed after every
tests which ends up in the suite failing due to missing reserved
resources. All the tests run alone work though. When the issue is fixed
they can then be added to the default list of tests to be run.

Fix bug in put_all(). That method was unused before this commit.
Clean the process list after the processes are stopped,
otherwise the suite eventually fails with a 'process terminated
prematurely' error. Before it was not necessary because it was not
reused (a new suite run was created).

Processes created have the scope of the test, so we should store
everything in a per-suite_run/per-test directory, otherwise everything
is stored in the same trial run_dir directory and it's really messy.

With the recent fix of the junit report related issues, another issue arose:
the 'with log.Origin' was changed to disallow __enter__ing an object twice to
fix problems, now still code would fail because it tries to do 'with' on the
same object twice. The only reason is to ensure that logging is associated with
a given object. Instead of complicating even more, implement differently.
Refactor logging to simplify use: drop the 'with Origin' style completely, and
instead use the python stack to determine which objects are created by which,
and which object to associate a log statement with.
The new way: we rely on the convention that each class instance has a local
'self' referencing the object instance. If we need to find an origin as a new
object's parent, or to associate a log message with, we traverse each stack
frame, fetching the first local 'self' object that is a log.Origin class
instance.
How to use:
Simply call log.log() anywhere, and it finds an Origin object to log for, from
the stack. Alternatively call self.log() for any Origin() object to skip the
lookup.
Create classes as child class of log.Origin and make sure to call
super().__init__(category, name). This constructor will magically find a parent
Origin on the stack.
When an exception happens, we first escalate the exception up through call
scopes to where ever it is handled by log.log_exn(). This then finds an Origin
object in the traceback's stack frames, no need to nest in 'with' scopes.
Hence the 'with log.Origin' now "happens implicitly", we can write pure natural
python code, no more hassles with scope ordering.
Furthermore, any frame can place additional logging information in a frame by
calling log.ctx(). This is automatically inserted in the ancestry associated
with a log statement / exception.

A bit of refactoring to fix logging and error reporting, and simplify the code.
This transmogrifies some of the things committed in
0ffb414406 "Add JUnit XML reports; refactor test
reporting", which did not fully match the code structuring ideas used in
osmo-gsm-tester. Also solve some problems present from the start of the code
base.
Though this is a bit of a code bomb, it would take a lot of time to separate
this into smaller bits: these changes are closely related and resulted
incrementally from testing error handling and logging details. I hope it's ok.
Things changed / problems fixed:
Allow only a single trial to be run per cmdline invocation: unbloat trial and
suite invocation in osmo-gsm-tester.py.
There is a SuiteDefinition, intended to be immutable, and a mutable SuiteRun.
SuiteDefinition had a list of tests, which was modified by the SuiteRun to
record test results. Instead, have only the test basenames in the
SuiteDefinition and create a new set of Test() instances for each SuiteRun, to
ensure that no state leaks between separate suite runs.
State leaking across runs can be seen in
http://jenkins.osmocom.org/jenkins/view/osmo-gsm-tester/job/osmo-gsm-tester_run/453/
where an earlier sms test for sysmo succeeds, but its state gets overwritten by
the later sms test for trx that fails. The end result is that both tests
failed, although the first run was successful.
Fix a problem with Origin: log.Origin allowed to be __enter__ed more than once,
skipping the second entry. The problem there is that we'd still __exit__ twice
or more, popping the Origin off the stack even though it should still remain.
We could count __enter__ recurrences, but instead, completely disallow entering
a second time.
A code path should have one 'with' statement per object, at pivotal points like
run_suites or run_tests. Individual utility functions should not do 'with' on a
central object. The structure needed is, in pseudo code:
try:
with trial:
try:
with suite_run:
try:
with test:
test_actions()
The 'with' needs to be inside the 'try', so that the exception can be handled
in __exit__ before it reaches the exception logging.
To clarify this, like test exceptions caught in Test.run(), also move suite
exception handling from Trial into SuiteRun.run_tests(). There are 'with self'
in Test.run() and SuiteRun.run_tests(), which are well placed, because these
are pivotal points in the main code path.
Log output: clearly separate logging of distinct suites and test scripts, by
adding more large_separator() calls at the start of each test. Place these
separator calls in more logical places. Add separator size and spacing args.
Log output: print tracebacks only once, for the test script where they happen.
Have less state that duplicates other state: drop SuiteRun.test_failed_ctr and
suite.test_skipped_ctr, instead add SuiteRun.count_test_results().
For test failure reporting, store the traceback text in a separate member var.
In the text report, apply above changes and unclutter to achieve a brief and
easy to read result overview: print less filler characters, drop the starting
times, drop the tracebacks. This can be found in the individual test logs.
Because the tracebacks are no longer in the text report, the suite_test.py can
just print the reports and expect that output instead of asserting individual
contents.
In the text report, print duration in precision of .1 seconds.
Add origin information and a traceback text to the junit XML result to give
more context when browsing the result XML. For 'AssertionError', add the source
line of where the assertion hit.
Drop the explicit Failure exception. We don't need one specific exception to
mark a failure, instead any arbitrary exception is treated as a failure. Use
the exception's class name as fail_type.
Though my original idea was to use raising exceptions as the only way to cause
a test failure, I'm keeping the set_fail() function as an alternative way,
because it allows test specific cleanup and may come in handy later. To have
both ways integrate seamlessly, shift some result setting into 'finally'
clauses and make sure higher levels (suite, trial) count the contained items'
stati.
Minor tweak: write the 'pass' and 'skip' reports in lower case so that the
'FAIL' stands out.
Minor tweak: pass the return code that the program exit should return further
outward, so that the exit(1) call does not cause a SystemExit exception to be
logged.
The aims of this patch are:
- Logs are readable so that it is clear which logging belongs to which test and
suite.
- The logging origins are correct (vs. parents gone missing as previously)
- A single test error does not cause following tests or suites to be skipped.
- An exception "above" Exception, i.e. SystemExit and the like, *does*
immediately abort all tests and suites, and the results for tests that were
not run are reported as "unknown" (rather than skipped on purpose):
- Raising a SystemExit aborts all.
- Hitting ctrl-c aborts all.
- The resulting summary in the log is brief and readable.

For all those API functions that directly use reserved_resources.get(), add a
'specifics' argument to be able to pick specific resources. For example, this
allows to pick a suite.bts(specifics={'type': 'osmo-bts-sysmo'})
I needed this to test error reporting for over-using resources, but will most
probably make sense in the future.

The "Affero" nature makes sense for the Osmocom network components like
BSC, SGSN, etc. as they are typically operated to provide a network
service.
For testing, this doesn't make so much sense as it is difficult to
imagine people creating a business out of offering to run test cases on
an end-to-end Osmocom GSM network. So let's drop the 'Affero' here.
All code is so far developed by sysmocom staff, so as Managing Director
of sysmocom I can effect such a license change unilaterally.

After a suite was done, the modem object would linger. If two suites were run
consecutively, the first suite's modem objects would still log incoming SMS.
Add an object cleanup mechanism in the SuiteRun class. Start by adding a
cleanup() to the Modem object and subscribing created modems there.
Move the modem_obj() function into SuiteRun, there is no use of it being
separate, and it makes for better logging.

Add missing code to free resources, not upon program exit, but when a suite is
done.
This allows running more than one suite in a row.
Also add a check to not attempt to free if there is nothing to be freed, to
avoid a regression test failure triggered when a suite exits without reserving
anything.

I would like to use the IP addresses also for OsmoBSC processes, so it is more
than clear now that 'nitb_iface' was the wrong naming choice.
The only distinction we may need in the future is public versus loopback
interface. To add that, we may add a trait to the 'ip_address' resource
like:
ip_address:
- addr: 10.42.42.1
type: public
- addr: 127.0.0.1
type: loopback
This way we can substitute public vs loopback addresses flexibly (e.g. using
scenarios).

The prompt() is useful for supervisor (user) interaction during tests.
However it had numerous problems:
- closed stdin, so second prompt() didn't work
- no editing
- no utf-8 multichar
- unflexible poll interval (poll often to stay responsive to input)
and unrelated:
- stdin was hijacked by subprocess.Popen
Firstly pass stdin=PIPE to all subprocesses to leave the tester's stdin
untouched.
Secondly use python input() to read the user entry (instead of mucking about
with the stdin fd), and import readline for history and editing features.
The old approach was put in place to allow polling DBus and processes
regularly. Instead, allow this by running input() in a separate thread while
polling regularly and slowly in the main thread.
The prompt code is now simpler, cleaner and works better.
Will be used in the upcoming 'debug' suite.

Clearly separate the kinds of BTS hardware the GSM tester knows ('type') from
the NITB's bts/type config item ('osmobsc_bts_type' -- not 'osmonitb_...' to

For BTS hardware kinds, use the full name of the binary for osmo driven models:
osmo-bts-sysmo, osmo-bts-trx, osmo-bts-octphy.

The original osmo-gsm-tester was an internal development at sysmocom, mostly by
D. Laszlo Sitzer <dlsitzer@sysmocom.de>, of which this public osmo-gsm-tester
is a refactoring / rewrite.
This imports an early state of the refactoring and is not functional yet. Bits
from the earlier osmo-gsm-tester will be added as needed. The earlier commit
history is not imported.
