+# Considerations:
+
+  1. Considers each file inside the path "dmm/scripts/csit/run/" as a single test case.
+  2. Considers all files inside "dmm/scripts/csit/run/" as Test scripts,
+     So any helper files can be written in the path "dmm/scripts/csit/"
+  3. Considers a test case as SUCCESS only when both the client and server echoes
+     DMM_CSIT_TEST_PASSED during verification.
+
+#################################################
+# Call stack of each test script from CSIT script:
+
+===============================================================================
+./test_script.sh  action  which_node     interface_name      dut1_ip   dut2_ip
+===============================================================================
+./test_script.sh  setup      0        dut1_to_dut2_if_name   dut1_ip   dut2_ip
+./test_script.sh  setup      1        dut2_to_dut1_if_name   dut1_ip   dut2_ip
+./test_script.sh  run        0        dut1_to_dut2_if_name   dut1_ip   dut2_ip
+./test_script.sh  run        1        dut2_to_dut1_if_name   dut1_ip   dut2_ip
+./test_script.sh  verify     0
+./test_script.sh  verify     1
+./test_script.sh  log        0

+./test_script.sh  cleanup    0
+./test_script.sh  cleanup    1

+#################################################
+# Want to write a new Test case ?
+
+  1. make a new script in "dmm/scripts/csit/run/" with the help of
+     "dmm/scripts/csit/template.sh".
+  2. And handle all the actions in it(can go through existing scripts for reference).
