The folders that concern + the end user are `test_cases/` and `test_list/`. + +**test_cases/:** + +This folder is used to store all the config files which are used to setup the + environment prior to a test. This folder is further divided into opnfv pods + which run QTIP. Inside each pod there are folders which contain the config + files segmented based on test cases. Namely, these include, `Compute`, + `Network` and `Storage`. The default folder is there for the end user who + is interested in testing their infrastructure but arent part of a opnfv pod. + +The structure of the directory for the user appears as follows +:: + + test_cases/default/compute + test_cases/default/network + test_cases/default/storage + +The benchmarks that are part of the QTIP framework are listed under these +folders. An example of the compute folder is shown below. +Their naming convention is <BENCHMARK>_<VM/BM>.yaml +:: + + dhrystone_bm.yaml + dhrystone_vm.yaml + whetstone_vm.yaml + whetstone_bm.yaml + ssl_vm.yaml + ssl_bm.yaml + ramspeed_vm.yaml + ramspeed_bm.yaml + dpi_vm.yaml + dpi_bm.yaml + +The above listed files are used to configure the environment. The VM/BM tag +distinguishes between a test to be run on the Virtual Machine or the compute +node itself, respectively. + + +**test_list/:** + +This folder contains three files, namely `compute`, `network` and `storage`. +These files list the benchmarks are to be run by the QTIP framework. Sample +compute test file is shown below +:: + + dhrystone_vm.yaml + dhrystone_bm.yaml + whetstone_vm.yaml + ssl_bm.yaml + +The compute file will now run all the benchmarks listed above one after +another on the environment. `NOTE: Please ensure there are no blank lines +in this file as that has been known to throw an exception`. + +Preparing a config file for test: +--------------------------------- + +We will be using dhrystone as a example to list out the changes that the +user will need to do in order to run the benchmark. + +Dhrystone on Compute Nodes: +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +QTIP framework can run benchmarks on the actual compute nodes as well. In +order to run dhrystone on the compute nodes we will be editing the +dhrystone_bm.yaml file. + +:: + + Scenario: + benchmark: dhrystone + host: machine_1, machine_2 + server: + +The `Scenario` field is used by to specify the name of the benchmark to +run as done by `benchmark: dhrystone`. The `host` and `server` tag are +not used for the compute benchmarks but are included here to help the +user `IF` they wish to control the execution. By default both machine_1 +and machine_2 will have dhrystone run on them in parallel but the user +can change this so that machine_1 run dhrystone before machine_2. This +will be elaborated in the `Context` tag. + +:: + + Context: + Host_Machines: + machine_1: + ip: 10.20.0.6 + pw: + role: host + machine_2: + ip: 10.20.0.5 + pw: + role: host + + Virtual_Machines: + +The `Context` tag helps the user list the number of compute nodes they want + to run dhrystone on. The user can list all the compute nodes under the + `Host_Machines` tag. All the machines under test must be listed under the + `Host_Machines` and naming it incrementally higher. The `ip:` tag is used + to specify the IP of the particular compute node. The `pw:` tag can be left + blank because QTIP uses its own key for ssh. In order to run dhrystone on + one compute node at a time the user needs to edit the `role:` tag. `role: + host` for machine_1 and `role: server` for machine_2 will allow for + dhrystone to be run on machine_1 and then run on machine_2. + +:: + + + Test_Description: + Test_category: "Compute" + Benchmark: "dhrystone" + Overview: > + ''' This test will run the dhrystone benchmark in parallel on + machine_1 and machine_2. + +The above field is purely for a description purpose to explain to the user +the working of the test and is not fed to the framework. + +Sample dhrystone_bm.yaml file: +------------------------------ +:: + + Scenario: + benchmark: dhrystone + host: machine_1, machine_2 + server: + + Context: + Host_Machines: + machine_1: + ip: 10.20.0.6 + pw: + role: host + machine_2: + ip: 10.20.0.5 + pw: + role: host + + Virtual_Machines: + + + Test_Description: + Test_category: "Compute" + Benchmark: "dhrystone" + Overview: > + ''' This test will run the dhrystone benchmark in parallel on + machine_1 and machine_2.\n + +Dhrystone on Virtual Machine: +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +To run dhrystone on the VMs we will be editing dhrystone_vm.yaml file. +Snippets on the file are given below. + +:: + + Scenario: + benchmark: dhrystone + host: virtualmachine_1, virtualmachine_2 + server: + + +The `Scenario` field is used by to specify the name of the benchmark to +run as done by `benchmark: dhrystone`.
