Abstract
========
+The testapi is used by all the test opnfv projects to report results.
+It is also used to declare projects, test cases and labs. A major refactoring
+has been done in Colorado with the introduction of swagger. The testapi is defined in Functest
+developer guide. The purpose of this project is to add more features to the testapi that automate
+the tasks that are done manually now, though there are tasks other than automation.

Overview:
=========
-
-
+The internhip time period was from Nov 14th to Feb 17th. The project prosposal page is here `[1]`_.
+The intern project was assigned to Svk Rohit and was mentored by S. Feng, J.Lausuch, M.Richomme.
+The link to the patches submitted is `[2]`_. The internship was successfully completed and the
+documentation is as follows.
Problem Statement:
------------------
+The problem statement could be divided into pending features that needed to be added into testapi
+repo. The following were to be accomplished within the internship time frame.
+
+* **Add verification jenkins job for the testapi code**
+ The purpose of this job is to verify whehter the unit tests are successful or not with the
+ inclusion of the patchset submitted.
+
+* **Automatic update of opnfv/testapi docker image**
+ The docker image of testapi is hosted in the opnfv docker hub. To ensure that the testapi image
+ is always updated with the repository, automatic updation of the image is necessary and a job
+ is triggered whenever a new patch gets merged.
+
+* **Automation deployment of testresults.opnfv.org/test/ website**
+ In the same manner as the docker image of testapi is updated, the testapi website needs to be
+ in sync with the repository code. So, a job has been added to the opnfv jenkins ci for the
+ updation of the testresults website.
+* **Generate static documentation of testapi calls**
+ The purpose of this is to give an static/offline view of testapi. If someone wants to have a
+ look at the Restful apis of testapi, he/she does't need to go to the website, he can download
+ a html page and view it anytime.
-Curation Phase
---------------
+* **Backup MongoDB of testapi**
+ The mongoDB needs to be backed up every week. Till now it was done manually, but due to this
+ internship, it is now automated using a jenkins job.
+* **Add token based authorization to the testapi calls**
+ The token based authorization was implemented to ensure that only ci_pods could access the
+ database. Authentication has been added to only delete/put/post requests.
+Curation Phase:
+---------------
+The curation phase was the first 3 to 4 weeks of the internship. This phase was to get familiar
+with the testapi code and functionality and propose the solutions/tools for the tasks mentioned
+above. Swagger codegen was choosen out of the four tools proposed `[3]`_ for generating static
+documentaion.
+Also, specific amount of time was spent on the script flow of the jenkins jobs. The automatic
+deployment task involves accessing a remote server from inside the jenkins build. The deployment
+had to be done only after the docker image update is done. For these constraints to satisfy, a
+multijob jenkins job was choosen instead of a freestyle job.

+FAQ's
+=====
+
+This section lists the problems that I have faced and the understanding that I have acquired during
+the internship. This section may help other developers in solving any errors casused because of the
+code written as a part of this internship.
+
+
+Test Api
+--------
+
+What is the difference between defining data_file as "/etc/.." and "etc/.." in setup.cfg ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If in the setup.cfg, it is defined as
+
+[files]
+data_files =
+etc/a.conf = etc/a.conf.sample
+
+then it ends up installed in the /usr/etc/. With this configuration, it would be installed
+correctly within a venv. but when it is defined as
+
+[files]
+data_files =
+/etc/a.conf = etc/a.conf.sample
+
+then it ends up installed on the root of the filesystem instead of properly be installed within the
+venv.
+
+Which attribute does swagger-codegen uses as the title in the generation of document generation ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It uses the nickname of the api call in swagger as the title in the generation of the document
+generation.
+
+Does swagger-codegen take more than one yaml file as input ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+No, swagger-codegen only takes one yaml file as input to its jar file. If there more than one yaml
+file, one needs to merge them and give it as an input keeping mind the swagger specs.
+
+
+Jenkins & JJB
+-------------
+
+Which scm macro is used for verification jenkins jobs ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are two macros for scm one is git-scm and other git-scm-gerrit. git-scm-gerrit is used for
+verification jenkins job.
+
+Does the virtualenv created in one build script exists in other build scripts too ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+No, the virtualenv created in one build script only exists in that build script/shell.
+
+What parameters are needed for the scm macros ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Project and Branch are the two parameters needed for scm macros.
+
+What is the directory inside the jenkins build ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The directory of the jenkins build is the directory of the repo. `ls $WORKSPACE` command will give
+you all the contents of the directory.
+
+How to include a bash script in jenkins job yaml file ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+An example might be apt here as an answer.
+
+builders:
+ - shell:
+ !include-raw: include-raw001-hello-world.sh
+
+
+How do you make a build server run on a specific machine ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It can be done by defining a label parameter 'SLAVE_LABEL' or in OPNFV , there are macros for each
+server, one can use those parameter macros.
+Ex: opnfv-build-defaults. Note, if we use macro, then no need to define GIT_BASE, but if one uses
+SLAVE_LABEL, one needs to define a parameter GIT_BASE. This is because macro already has GIT_BASE
+defined.
+
+What job style should be used when there is a situation like one build should trigger other builds
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+or when different build scripts need to be run on different machines ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+MultiJob style should be used as it has phases where each phase can be taken as a build scipt and
+can have its own parameters by which one can define the SLAVE_LABEL parameter.
