2019-11-18tests: support setting random seedKlement Sekera1-0/+5
Log the random seed used when running tests and provide means to re-use it in a later run. Type: feature Change-Id: I18d2a36ee802b901d4cca5577df41cec07f09cc0 Signed-off-by: Klement Sekera <ksekera@cisco.com> (cherry picked from commit 45a95dd782b91e9ae5665b5f95be4b6d7f99b879)
2019-11-18tests: avoid test runner hanging on child test process joinAndrew Yourtchenko1-1/+13
In parallel test, the single process is spawning a bunch of child processes running the tests, and communicates to them. When the child process signals that it has finished, the parent calls child.join(). Sometimes this join never returns. The result is a lot of defunct python processes, and the test run just hangs. I have seen this failure intermittently a fair bit in a busy containerized environment, and by chance, consistently reproduced it on a Thinkpad X280 with 8G of RAM and Ubuntu 19.04, which allowed to diagnose it.

2019-07-09tests: treat all truthy env vars the same wayPaul Vinciguerra1-5/+4
Introduce a new class, that returns the truthiness of a env var. Since an environment variable is just a string, it would normally be true if not unset. The new class returns true when the env var is set to a string that would be considered true.

2019-03-07make-test: Python pep8 compliance for sequencesNaveen Joy1-13/+13
For sequences, (strings, lists, tuples), use the fact that empty sequences are false. A tiny change towards getting full pep8 compliance, which will look good.

2019-02-26make test: Add exception handling around subprocess.Paul Vinciguerra1-3/+13
This cleans up exception catching to identify oserrors. By raising the specific exception closer to the offending call, we get additional stack history and can add clearer error logging to assist in troubleshooting.

2019-01-11Fix interactive testsjuraj.linkes1-2/+4
When running tests interactively (i.e. not using child process) the tests are split into small suites each containing tests from a VPPTestCase, but only the first suite is run. Fix this by creatin a new suite with all of these small suites in it and running that suite.

2018-11-09Fix logging into multiple filesjuraj.linkes1-1/+1
When running tests in one process, only one logger was used and each testcase added its own file handler, which resulted in logs appearing in multiple files. Fix this by restoring the creation of new loggers for each testcase and only reuse the stream handler from parent process.

2018-10-03test framework: add shell-style wildcard matching to filenamesAndrew Yourtchenko1-2/+5
Currently, one can either use "*" to denote all filenames, or to give the specific file name to run the tests in. This commit adds the possibility to run all tests matching the shell wildcard, e.g. TEST="test_acl_plugin*" will execute all ACL plugin testcases.

2018-08-23CSIT-1139: Implement parallel test executionjuraj.linkes1-158/+631
The implementation of parallel test execution in VPP Test Framework. - VPPTestCase test methods are grouped together - tests are running in separate processes - VPP instances spawned by tests are assigned to different cores - output from these processes is redirected through pipes and printed out testcase by testcase - TEST_JOBS env var is used to specify the number of parallel processes - improved test summary - a bit of code cleanup Change-Id: I9ca93904d9fe2c3daf980500c64a8611838ae28c Signed-off-by: juraj.linkes <juraj.linkes@pantheon.tech>

This change adds handling of special case when setUpClass throws. In this case TestResults receives a mock object called _ErrorHolder. By parsing its description, we find test class name and use it to lookup the test class in test suite to be able to add it to the list of failures for re-running.

Run tests in a forked process with a set of pipes to communicate keep-alives and overall result. This allows us to detect when e.g. vpp dies mid-API call causing the test to hang waiting for response (which will never come since vpp died). Support setting a (per test case) TIMEOUT make test option to set timeout, with a default timeout of 120 seconds. Example - fail the test suite if any test-case fails to finish within 300s: make TIMEOUT=300 test Change-Id: I0d04f26a7232968f4bf043adf5d5b508f5018717 Signed-off-by: Klement Sekera <ksekera@cisco.com>
