+
+This document describes the below list in detail.
+
+*  Building and Running the unit tests.
+*  Grouping of testcases.
+*  How to run different test suites.
+*  Support for skipped tests.
+
+
+
+Building and Running the unit tests
+-----------------------------------
+
+*  Create the meson build output folder using command.
+
+   ``$ meson <build_dir>``
+
+*  Enter into build output folder, which was created by above command.
+
+   ``$ cd build``
+
+*  Compile DPDK using command.
+
+  ``$ ninja``
+
+  The output file of the build will be available in meson build folder.
+  After successful ninja command, 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 command.
+
+   ``$ 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’`.
+
+    Ex: ``$ meson test --suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Commands to run testcases using option `--suite`
+
+*  Fast Tests should take less than 10 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:fast-tests``
+
+*  Performance Tests should take less than 600 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:perf-tests``
+
+*  Driver Tests should take less than 600 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:driver-tests``
+
+*  Below is the meson command to run Dump Tests
+
+   ``$ meson test --suite DPDK:dump-tests``
+
+
+
+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
+out 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:
+
+#. External library is not found.
+#. Config flag for the dependent library is 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 addition 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 examples shows how to export libraries and their header paths.
+
+To specify 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=/root/wireless_libs/zuc/:/root/wireless_libs/`` \
+                                                    ``libsso_kasumi/build/``
+        ``$ CFLAGS=-I/root/wireless_libs/zuc/include -I/root/wireless_libs/`` \
+                                        ``libsso_kasumi/include meson build``
+
+
+
+Summary
+--------
+
+*   To run all test cases
+       ``$ meson test``
+*   To run specific test
+       ``$ meson test testcase_name``
+        Ex:``$ meson test acl_autotest``
+*   To run specific test suite
+       ``$ meson test --suite DPDK:suite_name``
+        Ex:``$ meson test --suite DPDK:fast-tests``
