After +a successful ninja command, the binary ``dpdk-test`` is created in +``build/test/test/``. + +* Run the unit testcases:: + + $ ninja test + # or + $ meson test + +* To run specific test case via meson:: + + $ meson test <test case> + # or + $ ninja test <test case> + + +Grouping of testcases +--------------------- + +Testcases have been grouped into four different groups based on conditions +of time duration and performance of the individual testcase. + +* Fast tests which can be run in parallel. +* Fast tests which must run serially. +* Performance tests. +* Driver tests. +* Tests which produce lists of objects as output, and therefore that need + manual checking. + +Testcases can be run in parallel or non-parallel mode using the ``is_parallel`` argument +of ``test()`` in meson.build + +These tests can be run using the argument to ``meson test`` as +``--suite project_name:label``. + +For example:: + + $ meson test --suite DPDK:fast-tests + + +The project name is optional so the following is equivalent to the previous +command:: + + + $ meson test --suite fast-tests + + +Running different test suites +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The following commands are some examples of how to run testcases using option +``--suite``: + +* Fast Tests should take less than 10 seconds. The meson command to run them + is:: + + $ meson test --suite DPDK:fast-tests + +* Performance Tests should take less than 600 seconds. The meson command to + run them is:: + + $ meson test --suite DPDK:perf-tests + +* Driver Tests should take less than 600 seconds. The meson command to run + them is:: + + $ meson test --suite DPDK:driver-tests + +* The meson command to run Dump Tests is:: + + $ meson test --suite DPDK:dump-tests + + +Dealing with skipped testcases +------------------------------ + +Some unit test cases have a dependency on external libraries, driver modules +or config flags, without which the test cases cannot be run. Such test cases +will be reported as skipped if they cannot run. To enable those test cases, +the user should ensure the required dependencies are met. Below are a few +possible causes why tests may be skipped and how they may be resolved: + +#. Optional external libraries are not found. +#. Config flags for the dependent library are not enabled. +#. Dependent driver modules are not installed on the system. + +To help find missing libraries, the user can specify addition search paths +for those libraries as below: + +* Single path:: + + $ export LIBRARY_PATH=path + +* Multiple paths:: + + $ export LIBRARY_PATH=path1:path2:path3 + +Some functionality may be disabled due to library headers being missed as part +of the build. To specify an additional search path for headers at +configuration time, use one of the commands below: + +* Single path:: + + $ CFLAGS=-I/path meson build + +* Multiple paths:: + + $ CFLAGS=-I/path1 -I/path2 meson build + +Below are some examples that show how to export libraries and their header +paths. + +To specify a single library at a time:: + + $ export LIBRARY_PATH=/root/wireless_libs/zuc/ + $ CFLAGS=-I/root/wireless_libs/zuc/include meson build + +To specify multiple libraries at a time:: + + $ export LIBRARY_PATH=/path/zuc/:/path/libsso_kasumi/build/ + $ CFLAGS=-I/path/zuc/include \ + -I/path/libsso_kasumi/include \ + meson build -- 2.14.1
