Development and operations, DevOps, is in my opinion essential for getting things done with timely manner and it’s always good to hear how others are doing it by attending meetups. This time DevOps Finland went Mobile and we heard nice presentations about continuous delivery for mobile applications, mobile testing with Appium and the Robot Framework and efficient mobile development cycle. Compared to developing Web applications mobile brings some extra hurdles to jump but nothing that’s not solvable. Here are my short notes about the meetup.
The meetup was hosted by Zalando Technology at their new office here in Helsinki. Zalando is known to many as that online store that sells shoes, clothing and other fashion items but things don’t sell themselves and behind the scenes they have lots of technologies to keep things running. For the record I think they said that the meetup had 65 attendees of the 100.
They didn’t arrive to the final setup straightforward and it was iterative approach with how Git is used, code merged and releases done. Using Fastlane for all tedious tasks, like generating screenshots, dealing with code signing, and releasing your application made automating things easier. Interesting note was that their build server slaves are ansible managed Mac Minis on Rami’s desk. They had solved the problems nicely but testing is still difficult.
DevOps and rollbacks don’t work together, you roll forward.
Mobile testing with Appium and the Robot Framework
Mobile testing can be done with different tools and one option is to use Robot Framework just like for Web applications. Elmeri Poikolainen from Eficode demoed how to use Appium and run Robot Framework tests on real device. It has some limitations and I think with native applications it could be better to use native test tools like what Xcode has to offer.
Couple of weeks ago at Tampere goes Agile the question was what’s beyond agile and partial answer was DevOps. I’ve read about DevOps before and tried to introduce it to use in my daily job but new things move slowly. So, it was good time to hear more about DevOps and how others are using it at DevOps Finland meetup about ApiOPs and Test Automation. The meetup was held at GE Healthcare building in Vallila and organized by Eficode. Delicious coffee and sandwiches were from Warrior coffee. Here’s my short notes about the topics discussed.
The talk was more about mindset related to developing APIs than tools but Swagger was mentioned for representing your API and SoapUI for testing. For API management Moilanen talked about APInf which is an API management platform.
Test automation with Robot Framework
Eficode guys talked about Test automation with Robot Framework which is a generic test automation framework for acceptance testing and acceptance test-driven development (ATDD). It’s originally developed in Nokia Networks 2005 and open sourced in 2006. Robot Framework uses keyword-driven testing approach and it’s capabilities can be extended by test libraries implemented either with Python or Java. Robot Framework is quite big in Finland but to get the work forward and more known worldwide there’s now Robot Framework Association put together by Eficode, Omenia, Reaktor, Eliga, Knowit, Qentinel and HiQ.
After some technical difficulties with projector we heard intro to Robot Framework with Selenium2Library and saw video about using it. Selenium is a suite of tools to automate web browsers and with Selenium2Library you can use it with Robot Framework to easily implement and maintain automatic browser testing of your web application. Another use case which I find interesting is for testing REST APIs.
You can use Robot Framework in many was as we saw with the demo of a machine for automating payment terminal testing which Eficode had built (slides, blog post in Finnish). It was a Shapeoko 2 CNC milling machine where Arduino parsed g-code sent over terminal bus, payment terminal was captured with Tesseract OCR and it was controlled by Robot Framework running in Raspberry Pi. They had extended Robot Framework with new libraries for communicating over serial bus and reading images from Raspberry Pi camera.
What you can do with Robot Framework is up to you as the framework doesn’t limit you.
Future of DevOps Finland
The last talk of the meetup was about the future of DevOps Finland. DevOps Finland was started in 2013 by Erno Aapa and now the load is distributed over new planning team to keep things active. Sharing is caring and so we were encouraged to share our experiences and war stories about DevOps by talking in some future meetup.
Some possible future themes for the meetup were also discussed.
e.g. Coreos, Mesos, Kubernetes, AWS tools, Rancher.
DevOps on Windows
PoweShell and Azure.
DevOps without computers
AWS lambda, heroku, dokku, aws beanstalk, Google app engine, IBM Bluemix. (DevOps as a service).
