2019-09-18suite_test: suite requires the fake trial to implement get_run_dir()Pau Espin Pedrol1-5/+24
If class Test calls get_run_dir(), it will generate the run dir from Suite.get_run_dir() + append, and Suite.get_run_dir() in turn will do the same with Trial.get_run_dir(). In suite_test.py, however, we are passing a plain log.Origin object (parent of Trial), which doesn't implement this function. We need to add it since tests will start using get_run_dir() to write their own log files. Generated tmp files are deleted on success and left there on error, in order to be able to debug stuff easily. Change-Id: Ic8326659a9ced0351e1e7e57ef21ce36f777729a

It's always been the default anyway, so no need to explicitly state it. Furthermore, recently (osmobsc 167cb828665b91ed7d28007abd4a1862ebbb78c9) force-combined-si was enabled by default for nanoBTS due to issues with some MS not registering when it's not enabled, so let's osmo-bsc decide were should it be enabled.

2018-08-21Introduce scenario modifiersPau Espin Pedrol5-2/+199
Before this patch, scenarios were only used to select resources with specific attributes. This commit introduces "modifiers" in scenarios, which allows setting or modifing config attributes of resources once they have been reserved. This way same test can be run selecting same resources but modifying its configuration, allowing for instance running different number of TRX, different timeslot configuration, etc. Modifiers are described by placing a "modifiers" dictionary in any scenario file, similar to the current "resources" one used to select requird resources. The "modifiers" dictionary is overlaid on top of the "resources" one resulting from combining all the "resources" dictionary of all scenario files.

We are using the CDF to decide which percentage of the jobs should be running at a given point. The x-axis is time and the y-axis the percentage of how many jobs should be running. There are three functions to do this.

2017-09-16resource: Handle lists correctly in item_matchesPau Espin Pedrol4-5/+41
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).

2017-09-16config: Fix combination of listsPau Espin Pedrol2-0/+118
This commit fixes combination of resources containing lists. For lists containing complex types, it has been decided to handle them as sorted list, where position in list matters. In this case, combine is called recursively for each element in dest and src sharing position in the list, and assumes that if one list is shorter than the other, then it has to be combined against empty set for that tye. For instance this is useful when defining trx_list properties, where a BTS can have a different amount of TRX but we may be interested in restricting the first TRX and don't care about extra TRX. For lists containing simple types (eg. integers or strings), we just want to merge both lists and we only need to check if the value is already there, ie. handle them as unsortered sets. This case won't work if we call combine for each element of the list because for a simple case it will just end up checking if a[i] == b[i]. This kind of operation for simple types is needed in later commits where cipher attribute is introduced. Without this patch, having following 2 scenarios and trying them to use together "-s foosuite:cipher-a50+ciphera51" will fail: cipher_a50.conf: bts: - ciphers: - 'a5 0' cipher_a51.conf bts: - ciphers: - 'a5 1' ValueError: cannot combine dicts, conflicting items (values 'a5 0' and 'a5 1') Change-Id: Ib7a38f10eb9de338a77bf1fa3afceb9df1532015
2017-09-16Replicate resources based on times attr before combine timePau Espin Pedrol5-3/+184
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.

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.

2017-07-20remove timer section from osmo-{bts,bsc}.cfg.tmplHarald Welte2-22/+0
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.

2017-06-18Add support for SMPP testingPau Espin Pedrol3-10/+32
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.

2017-06-13fix and refactor logging: drop 'with', simplifyNeels Hofmeyr8-77/+66
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.

2017-06-09refactor: fix error handling; fix log.Origin; only one trialNeels Hofmeyr6-46/+98
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.

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.

2017-05-08log.py: tweak LogTarget list, require explicit LogTargetNeels Hofmeyr1-1/+1
Rename log_sink to log_write_func to make it more clear. Remember the list of log targets as static member LogTarget.all_targets. Make each LogTarget instance register with the list of targets implicitly. No longer create a default log target, rather create one explicitly in osmo-gsm-tester.py.

2017-05-04config: resolve real paths from symlinks, add paths debug loggingNeels Hofmeyr4-2/+18
Tweak test expectations to include the new debug logging. Go through the paths in alphabetical order to get deterministic logging output, so the test expectations always match. Change-Id: I11a905b2467cda691d9ccea30ae436bac96476c9
