As described in https://osmocom.org/issues/2380 and related gerrit
patch https://gerrit.osmocom.org/#/c/3306 the config files currently
contain timers with a 'zero' value, leading to issues.
The config file templates used in osmo-gsm-tester suffer actually
from exactly the same issue: They basically contain values that were
written back to the file based on the default initialization in libbsc,
which unfortunately was zero in some cases.
Let's remove those values, they are the (bad) default anyway.
libbsc patches in the pipeline will introduce reasonable defaults
and forbid the use of zero for timers.

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.

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
0ffb41440661631fa1d520c152be4cf8ebd4c46b "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.

resolution.
In the regression tests' expectations, some duplicate entries in the origins
are removed, and hence no list of deeper origin ancestry is printed anymore.

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.

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).

* Add Junit output file support
* Differentiate between an expected failure test and an error in the
test, as described in JUnit.
* In case of an error/exception during test, record and attach it to the
Test object and continue running the tests, and show it at the end
during the trial report.

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
stay in tune with future developments: it is the libbsc that needs this).
For BTS hardware kinds, use the full name of the binary for osmo driven models:
osmo-bts-sysmo, osmo-bts-trx, osmo-bts-octphy.
