- Arguments controlling test runs:
- V=[0|1|2] - set test verbosity level
- 0=ERROR, 1=INFO, 2=DEBUG
- TEST_JOBS=[<n>|auto] - use at most <n> parallel python processes for test execution, if auto, set to number of available cpus (default: 1)
- MAX_VPP_CPUS=[<n>|auto]- use at most <n> cpus for running vpp main and worker threads, if auto, set to number of available cpus (default: auto)
- CACHE_OUTPUT=[0|1] - cache VPP stdout/stderr and log as one block after test finishes (default: 1)
- FAILFAST=[0|1] - fail fast if 1, complete all tests if 0
- TIMEOUT=<timeout> - fail test suite if any single test takes longer than <timeout> (in seconds) to finish (default: 600)
- RETRIES=<n> - retry failed tests <n> times
- DEBUG=<type> - set VPP debugging kind
- DEBUG=core - detect coredump and load it in gdb on crash
- DEBUG=gdb - allow easy debugging by printing VPP PID
- and waiting for user input before running
- and tearing down a testcase
- DEBUG=gdbserver - run gdb inside a gdb server, otherwise
- same as above
- DEBUG=attach - attach test case to already running vpp in gdb (see test-start-vpp-in-gdb)
-
- STEP=[yes|no] - ease debugging by stepping through a testcase
- SANITY=[yes|no] - perform sanity import of vpp-api/sanity vpp run before running tests (default: yes)
- EXTENDED_TESTS=[1|y] - used by '[re]test-all' & '[re]test-all-debug' to run extended tests
- TEST=<filter> - filter the set of tests:
- by file-name - only run tests from specified file, e.g. TEST=test_bfd selects all tests from test_bfd.py
- by file-suffix - same as file-name, but 'test_' is omitted e.g. TEST=bfd selects all tests from test_bfd.py
- by wildcard - wildcard filter is <file>.<class>.<test function>, each can be replaced by '*'
- e.g. TEST='test_bfd.*.*' is equivalent to above example of filter by file-name
- TEST='bfd.*.*' is equivalent to above example of filter by file-suffix
- TEST='bfd.BFDAPITestCase.*' selects all tests from test_bfd.py which are part of BFDAPITestCase class

-
- VARIANT=<variant> - specify which march node variant to unit test
- e.g. VARIANT=skx test the skx march variants
- e.g. VARIANT=icl test the icl march variants
-
- COREDUMP_SIZE=<size> - pass <size> as unix { coredump-size <size> } argument to vpp
- e.g. COREDUMP_SIZE=4g
- COREDUMP_SIZE=unlimited
- COREDUMP_COMPRESS=1 - compress core files if not debugging them
- EXTERN_TESTS=<path> - path to out-of-tree test_<name>.py files containing test cases
- EXTERN_PLUGINS=<path> - path to out-of-tree plugins to be loaded by vpp under test
- EXTERN_COV_DIR=<path> - path to out-of-tree prefix, where source, object and .gcda files can be found for coverage report
-
- PROFILE=1 - enable profiling of test framework via cProfile module
- PROFILE_SORT_BY=opt - sort profiling report by opt - consult cProfile documentation for possible values (default: cumtime)
- PROFILE_OUTPUT=file - output profiling info to file - use absolute path (default: stdout)
-
- TEST_DEBUG=1 - turn on debugging of the test framework itself (expert)
-
- SKIP_AARCH64=1 - skip tests that are failing on the ARM platorm in FD.io CI
-
- RND_SEED=seed - Seed RND with given seed
-
- Starting VPP in GDB for use with DEBUG=attach:
-
- test-start-vpp-in-gdb - start VPP in gdb (release)
- test-start-vpp-debug-in-gdb - start VPP in gdb (debug)
-
- Arguments controlling VPP in GDB runs:
-
- VPP_IN_GDB_TMP_DIR - specify directory to run VPP IN (default: /tmp/unittest-attach-gdb)
- VPP_IN_GDB_NO_RMDIR=0 - don't remove existing tmp dir but fail instead
- VPP_IN_GDB_CMDLINE=1 - add 'interactive' to VPP arguments to run with command line
