2022-05-10tests: replace pycodestyle with blackKlement Sekera1-4/+5
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

2022-02-17tests: make tests less make dependentKlement Sekera1-2/+5
Implement command line argument parsing instead of passing arguments via environment variables. Add script for running tests without having to invoke make. Deprecate running tests via make.

2021-04-16tests: cpus awarenessKlement Sekera1-1/+1
Introduce MAX_CPUS parameters to control maximum number of CPUs used by VPP(s) during testing, with default value 'auto' corresponding to all CPUs available. Calculate test CPU requirements by taking into account the number of workers, so a test requires 1 (main thread) + # of worker CPUs. When running tests, keep track of both running test jobs (controlled by TEST_JOBS parameter) and free CPUs. This then causes two limits in the system - to not exceed number of jobs in parallel but also to not exceed number of CPUs available. Skip tests which require more CPUs than are available in system (or more than MAX_CPUS) and print a warning message.

2021-04-12tests: support attaching to existing vppKlement Sekera1-2/+2
Introduce a new option DEBUG=attach to run a test against existing already running vpp. A new target 'make test-start-gdb' will spawn VPP in gdb for this purpose. Customization options explained in test-help. Type: improvement Change-Id: Ia160a85b33da3b2df292d44bb95729af9dd9da96 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2019-11-05misc: Fix python scripts shebang lineRenato Botelho do Couto1-1/+1
Type: fix Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python' as a valid shebang line. It requires scripts to explicitly chose between python2 or python3. Change all to use python3 as suggested by Paul Vinciguerra.

2019-11-05tests: support setting random seedKlement Sekera1-0/+3
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>
2019-06-24tests: refactor VppDiedError.Paul Vinciguerra1-2/+1
- Move Exception into same module as TestCase. - Move the error reporting logic inside the error. - Allows testing of the returncode and signal_name for tests to consume. - Fix the signal reporting code: VppDiedError: VPP subprocess died unexpectedly with returncode -6 [unknown]. displays as: VppDiedError: VPP subprocess died unexpectedly with return code: -6 [SIGABRT].

2018-11-26Split non-parallel testsuitejuraj.linkes1-1/+6
Split one big suite into smaller suites when not running tests in parallel. This results in all tests being executed in one iteration. Change-Id: I0d3d357a95d9cc596b606d5911a5819e8ffdeee5 Signed-off-by: juraj.linkes <juraj.linkes@pantheon.tech>

2017-08-10make test: detect hung testsKlement Sekera1-2/+8
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>
2017-04-10make test: automatic "vpp finishes startup" checkKlement Sekera1-0/+26
Add code which checks if vpp doesn't crash/exit immediately after startup to aid debugging stuff like mistyped graph node name or so. Refuse to run tests if the vpp is unable to start, complain loudly and print vpp's stderr at critical log level if this happens to make spotting these problems in jenkins easy.
