- Hello everyone, thank you for attending today. We concerned about many sudden cancellation but fortunately today is not. Before I start my session, I'd like to say to thank for today's all attendees. Be the central on your field. I think this title looks a little arrogant but I decided to use this title because the main theme of this year’s Rakuten Technology Conference is ‘Leaders for the future’. And hoped to share what I experienced and support all attendees to be the central on your field.
- Name / SCM / Favorite Language This QR code is link to my twitter account, So please follow me if you’ve anything.
- I said it was difficult to decide presentation theme. It also took a time to decide title. I think you guess why this session’s title is ’Be the central on your field’ I’m gonna show you what does it mean
- Actually, the title is derived from Japanese famous novel, ’Crying out love, In the center of the world’.
- I read this novel and little cried so it was a trigger for me that I’ll do the best whatever I do at everywhere and whenever. So I just utilized the title praying for my session to be helpful for today’s all attendees. Originally, I planned to give a session with technical contents such as Test Automation, Improving to load frontend page, Team/Project Management with Agile, Scrum, Kanban. But I thought we’ve already enough technical contents at the other site with live streaming or other lightning talks talking about some technical issues. So I decided to talk about engineer's mindset based on my experience.
- Let me introduce my background. As I said in my profile, I’m from South Korea. I'm ex-captain leading one company and these pictures are what I was taken when I marched and lead a night training. you know, Scrum, the most famous agile dev process, is created by Jeff who was ex-pilot graduated from American Western Point. ---------------------------------------------------------------------------------------------------- And the following pictures were taken at Korean Government. At that time I was a representative of all students trying to go abroad to work and attended to some of the press conferences. This man is minister of Ministry of Employment and Labor. He is turning his back on my eye but anyway I was honored.
- In Japan, Currently I'm just ordinary employee but I keep trying to stand for the center wherever I am. By doing scrum master of frontend team and leading small team such as test automation, suggesting the better practice at conferences proactively, I'm trying to get knowledge, experience, credit to be one of leaders in this field.
- This is my story.
- When I start to decide that, there was a theme I was interested in. It’s about frontend test automation.
- At that time. We Rakuten Ranking had a big issue. You know, tests in development process consist of this 3 tests. Unit Test / Function Test / System Test. On the step of system test, we need to check that all the existing features are deserved after modifying or adding new feature. To release a new feature, we needed to execute regression test as one way of system test, Accessing to particular page, clicking and But the problem was .. It took so long time to test all features because we corresponded to the test manually It took about 20 hours per each tests because there are too many cases to check.
- It was a big bottleneck for us. The cost resulted in pressure for our engineer’s resource. We wanted to concentrate on service improvement itself but We couldn’t help using our time to execute the manual test for making sure the new feature has no problem..
- So anyway I decided to automate the process. I could calculate ROI saying that we can save 20 hours every time we test and It means we can save 6 thousand yen per one time. If it’s continued, we can restore unlimited time and business resources and engineers can concentrate on service improvement.
- After comparing some test framework, I decided to use Selenium and stood on start line..
- The challenge was big. It was first time to use Selenium but unfortunately document was old and not enough. Furthermore, we had many parts to develop. At that time, I used my almost time to understand Selenium and think about proper test scope and decide test strategy. And I set a goal that I’ll automate all test cases in 6 months. And accomplished the goal.
- After understanding Selenium itself and developing our application, When I arrived at the first goal, I was surprised. The Road was divided two line. / That was not the END. That was just start and I could see more beyond Selenium itself. Such as many discussion about test quality, community activities. At that time, I realized that … Oh this road is NOT one straight line. There are another straight lines. It maybe the road to the center. I thought If I walk on this road, I can learn more and see the bigger world.
- I could see the road which I hadn’t never seen. I was just living in 2D world so far. I felt the importance seeing something others from variety of aspects to understand this 3D world. By … To our test application be better and for me to be more central, I wanted to keep trying something.
- About networking, I attended to many study related with test automation, Selenium and Tried to connection with the other engineers who are having same trouble about Test Strategy something like that. there was an international conference Selenium User Community held on last April at Tokyo. Luckily I could get an opportunity to give a session. The theme I talked was mainly about cost improvement and resource management with Selenium.
- Actually it was my first trial of giving session on big stage, I was little nervous but finished it successfully. And took a picture with the project leader of Selenium. Thanks to attending the event, I could get familiar with the organizers of Japan Selenium User Community,
- So collaborating with them, I held a test automation study, it’s named E2E Test Automation Day. I think some of today’s attendees attended to the event, I was surprised and impressed on the passion of engineers at Selenium Conference, but the event was held in Tokyo so I just wanted to lead the passion to Kansai. And I believe it was a good chance for Kansai engineers to be familiar with test automation field.
- About analyzing, I tried to find the way to improve our test application. I analyzed a variety of examples. Reading books, articles and magazines I kept finding the best practice. Our application could cover all test cases but it had some performance issues. So analyzed examples for utilizing CPU enough diminishing processing time. And adopted some of the features to our application and testing some features is on going.
- Selenium Grid, it provides distributed execution environment. It can diminish all the processing time dramatically by allocating each missions like Safari on MacOS to each nodes. You can image it easily. It’s like clustering technology like distributed file system.
- Using docker, We ranking Frontend team already dockerized our web application and created CI/CD pipeline. So I’m considering to dockerize test application to integrate maintenance cost.
- Actually adopted already but anyway page object pattern Which is making maintenance cost lower by dividing classes for test scenario and getting web elements on DOM.
- Originally I thought we are on the straight line of life. Because we are used to listening that Life is like Marathon. But the thinking was changed. (Click) We are in somewhere on the straight line but Another line also exists. Nobody knows how many are the lines. There is no END. Maybe we can define the world is all / which is enclosing us and actually the thing which looked multiple straight lines is NOT unlimited straight line BUT ..
- Big circle surrounding us.
- Like galaxy on space. Galaxy is unknown area. So The most important thing is knowing where am I and understand my status to evaluate my current objectively. Corner? Edge? or Center? If we can understand what it is, we must keep trying to find where is the central.
- As an engineer of Rakuten, Japan and the World, I propose that you decide to be a leader on your field. To achieve that, we need to be more central to expand our energy to the external. We all have unlimited potentiality. We can improve our organization, field and society.
- Don’t be shy You are the only one in your circle You are main character in your field, in your life. And you are a leader leading the field. Do something proactively and Call out to all proactively. All will be your supporter.
- Love the group you belong to. In my case, this company Rakuten supported many things to me. Budget for holding event, fee for business trip and so on. The group can be your stage. And Love it and show off your ownership Like you do something for your girlfriend or boy friend wife, husband as usual.
- Expand your circle more and more By networking with others
- Merge your circle with others To maximize the impact on your field.
- Leave the commit logs. It will be a new engine for your next when you are burnt out.
- That's all from me. Please talk with a man who is with pumpkin hair band and our staffs. We Rakuten always wait for the leaders for the future like you. and please find me if you've any question at after party And let's enjoy today's the rest.
