Feng, J.Lausuch, M.Richomme + +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. + +Version history +=============== + ++------------+----------+------------------+------------------------+ +| **Date** | **Ver.** | **Author** | **Comment** | +| | | | | ++------------+----------+------------------+------------------------+ +| 2016-11-14 | 0.0.1 | Morgan Richomme | Beginning of the | +| | | (Orange) | Internship | ++------------+----------+------------------+------------------------+ +| 2017-02-17 | 0.0.2 | S.V.K Rohit | End of the Internship | +| | | (IIIT Hyderabad) | | ++------------+----------+------------------+------------------------+ + +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. + +* **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. + +Important Links: +---------------- + +* MongoDB Backup Link - `[4]`_ +* Static Documentation - `[5]`_ +* TestAPI Token addition to ci_pods - `[6]`_ + +Schedule: +========= + +The progress and completion of the tasks is described in the below table. + ++--------------------------+------------------------------------------+ +| **Date** | **Comment** | +| | | ++--------------------------+------------------------------------------+ +| Nov 14th - Dec 31st | Understand Testapi code and the | +| | requirements. | ++--------------------------+------------------------------------------+ +| Jan 1st - Jan 7th | Add jenkins job to create static | +| | documentation and write build scripts. | ++--------------------------+------------------------------------------+ +| Jan 8th - Jan 21st | Add verification jenkins job for unit | +| | tests. | ++--------------------------+------------------------------------------+ +| Jan 22nd - Jan 28th | Add jenkins job for mongodb backup | +| | | ++--------------------------+------------------------------------------+ +| Jan 29th - Feb 11th | Enable automatic deployment of | +| | testresults.opnfv.org/test/ | ++--------------------------+------------------------------------------+ +| Feb 12th - Feb 17th | Add token based authentication | +| | | ++--------------------------+------------------------------------------+ + +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. + +References: +=========== + +_`[1]` : https://wiki.opnfv.org/display/DEV/Intern+Project%3A+testapi+evolution + +_`[2]` : https://gerrit.opnfv.org/gerrit/#/q/status:merged+owner:%22Rohit+Sakala+%253Crohitsakala%2540gmail.com%253E%22 + +_`[3]` : https://docs.google.com/document/d/1jWwVZ1ZpKgKcOS_zSz2KzX1nwg4BXxzBxcwkesl7krw/edit?usp=sharing + +_`[4]` : http://artifacts.opnfv.org/testapibackup.html + +_`[5]` : http://artifacts.opnfv.org/releng/docs/testapi.html + +_`[6]` : http://artifacts.opnfv.org/functest/docs/devguide/index.html#test-api-authorization |
