Continuous Integration is an increasingly popular topic in modern software development. Across many industries the companies acknowledging the importance of IT and delivering value to their customers through great software prevail against their competitors. Many reports indicate that Continuous Integration is one of the major contributing factors to developing high quality software with remarkable efficiency. There are many excellent articles, talks and books explaining the principles of CI in theory. During the lecture System Engineering and Management, we had the opportunity to apply our abstract knowledge and gain our own experience by creating and operating a CI pipeline in an accompanying project. The following article covers the approach, major challenges and most important the lessons learned of our Continuous Integration endeavor. By pointing out relevant issues we want to raise awareness on our misconceptions and mistakes we committed so you can avoid them in the first place.

In this article we would like to describe, how to write unit- and gui-tests for an Android-Application in Android Studio and how-to automat these tests on Jenkins.
Tools and frameworks
We used the following tools and frameworks to write and automate our tests:
- Android Studio
To test the basic functionality of your app, the best way is to run a unit-test. Continue reading

This article will run you through the motivation for a continuous integration and delivery, choosing a corresponding tool and a server to run it on. It will give you a brief overview over IBM Bluemix and kubernetes as server solution and then discuss the application for a virtual machine inside a company. There are some useful instructions (for beginners) on generating key-pairs for the server on Windows. Next there is a motivation why to run Jenkins (the CI tool of choice) as docker container and gives some instructions to get started. Finally, frequent problems are discussed which hopefully save some of your time.
Building an HdM Alexa Skill – Part 4
This is the last part in our series of blog posts concerning the development of an Alexa Skill. If you missed the previous parts you can catch up by reading part 1 here, part 2 here and part 3 here.
Every student group that has worked on a software project can retell the following situation: you’re one week ahead of the deadline, every team member has spent the last weeks working on their part of the project. So far, everything looks great – every module works on its own, the GUI is designed and implemented, the database is modeled and set up, client and server are both running smoothly. All that’s left is combining all the bits and pieces to see everything in action together. Easy, right? Fast forward another five days, it’s the weekend before the final presentation: the air is thick with panic with everyone furiously debugging their code, solving merge conflicts left and right while trying to get the project to some kind of working state that will at least survive the demo. Things that were already working in isolation are now broken and quite a bunch of features that were an inch close to completion will never make it into the presentation. So what has gone wrong? And what have we done to prevent the same from happening with our Alexa Skill?
Choosing the correct build system for your game project
In this blog entry we take a look at Travis CI, Jenkins, Gitlab CI and Buildbot and evaluate their benefits and downsides when trying to build a content heavy project with it (e.g. games). Continue reading
Microservices – Legolizing Software Development IV
Welcome to part four of our microservices series. If you’ve missed a previous post you can read it here:
IV) Continuous Integration
V) Lessons Learned
In our fourth part of Microservices – Legolizing Software Development we will focus on our Continuous Integration environment and how we made the the three major parts – Jenkins, Docker and Git – work seamlessly together.
Continuous Integration with Travis CI and Amazon Webservices
In the the course Software Engineering and Management and Interactive Media at Stuttgart Media University, we launched an interactive web application called Emoji College.
The following blog entry is a brief description of what is going on in this project. The main focus relies on the implementation of a continuous integration pipeline with TravisCI and hosting with AWS. As newcomers in dealing with AWS services it was not easy for us to get started. We have had to try a lot and have paid too much money for the services. Therefore it is our mission to explain the most important steps during the setup of AWS services easily and mention all the lessons learned. So far, there is no easy and understandable guide as we needed it.
Building a HdM Alexa Skill – Part 1
Introduction to the Project
It is becoming obvious that chatbots are quickly emerging to the next Big Thing. This is especially evident by the recent flood of publication of software development kits by major tech companies to encourage developers to build applications for their ecosystem.
