Vishal talks about Mercari's Software Engineering in Test (SET) team and their work on improving productivity. The SET team provides tools and environments to help engineers and QA test efficiently. They work on local development environments, continuous integration, QA environments, and device farms. Some current focuses are improving tools for microservices development and mobile app testing given the growing code bases. The presentation encourages the audience to join the SET team if interested in these challenges.

10. What we do?
10
For Engineers
➔ Provide 1 command local dev
environment
➔ Setup CI & integrate cloud
services
➔ Setup environments for Security
assessment
For QA
➔ Provide 1 click QA environment
➔ Setup device farm

11. How we do?
➔ For local dev environment : mercari-mini3
➔ For QA environment : QA Tool
➔ For Device Farm : OpenSTF
➔ For CI & monitoring : jenkins / circleci / sentry …
➔ Etc etc ...

12. mercari-mini3
● Version 3
● Based on docker for Mac & docker-compose
● Build docker images on Jenkins whenever needed
● Run API, Web, WebView, Admin, DB & dependencies
● Works for all regions
12

14. QA Tool
● Based on mini3
● Runs on GCP
● Using this QA can create dev environment for any
service / any branch
14
At Mercari, before merging branches to master, QA do end to end
testing on branch itself

19. Device Farm
● We use OpenSTF
● Running on Google Cloud
● Devices are connected locally in US & JP office on
mac-mini
● Anyone can access any device from anywhere

22. What is NEXT?

23. Microservices Architecture
● Local dev environment
○ Current mini3 is not scalable. We cannot make
developers to run 100+ services locally
Working on designing kubernetes cluster in such as way
that developers will be able to develop by running
dependencies on cloud itself instead of local by using
tools such as Telepresence
23

24. Microservices Architecture
● QA Environment
○ Again fury-panda is not scalable for microservices
architecture. We need better solution
Working on developing kubernetes controller which will
use github & kubernetes API to create new pods when
Github PRs are created
24

25. Client Side (Android / iOS)
● Mobiles apps are getting bigger
○ Manual QA is not scalable
○ Current test infrastructure is not adequate and
reliable
Need more reliable solutions for mobile e2e automated
testing.
