Pau Espin cbc724204c suite_test: Update tests to check new feature fixes
Now that combination and matching of lists works properly, update the
suite test to check a more complex scenario.

Pau Espin 5847551640 resource: Handle lists correctly in item_matches
We want to handle lists in the same way as we handle them in combine().
Without this commit, reserve()->find() failed to match objects
containing dictionaries inside lists correctly (such as trx configs).

A few attributes are added to trx_list of some resources in
suite_test/resources.conf to show a case in which resource reservation
would fail without this patch. It failed because before this patch,
dictionaries inside lists are compared to be equal instead of being
compared element by element to see if one dictionary is a subset of the
other one (for each element in the lists).

Pau Espin 0b30279c2f Replicate resources based on times attr before combine time
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.

Pau Espin b26f32a955 nominal_power and max_power_red attrs can now be set per resource
Before this commit, only max_power_red was specified and it could only
be used as a defaults and could not be set per object. Together with
nominal_power, it can be useful to be able to set them to different
values for different objects, as for example different osmo-bts-trx
objects can require different values.

Neels Hofmeyr 6ccda11a98 refactor: fix error handling; fix log.Origin; only one trial
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.

Neels Hofmeyr b8011695b8 cosmetic: review mo_mt_sms.py's logging
Implement the Modem.log_info() function, use that instead of logging all modem
properties.

Tweak mo_mt_sms.py print() statements.

Pass modem object to SMS generation to inlcude the modem name as SMS token.

Neels Hofmeyr 76d8103bfb rename resource nitb_iface to ip_address
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).

Pau Espin 0ffb414406 Add JUnit XML reports; refactor test reporting
* 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.
