Visit to the Java Forum in Stuttgart on 05.07.2018

Friday, 06 July 2018

Every year, the Java Forum held at Liederhalle, in Stuttgart, offers the opportunity to gain comprehensive information about topics related to Java and software architecture. Anke and Dennis took this opportunity and participated in the various lectures for WidasConcepts.

The highlights include the following presentations:

Research findings and personal experiences with Test-Impact-Analysis – Dr. Elmar Juergens (CQSE GmbH)

The “Test-Impact-Analysis” analyzes already implemented unit and integration tests in such a way that when code changes, only those tests are performed, which were affected by the corresponding changes. In his talk, Dr.Elmar Juergens (CQSE GmbH) presented the execution of a wide variety of test suites of open-source-based tools via tree maps and showed the empirically measured, partly significantly reduced runtimes.

JUnit 5 & Testcontainers – Testing in the times of Java 10 and Docker – Tim Riemer (FNT GmbH)

The new version 5 of the popular Java-based test libraries, which was released in late 2017, is compatible with Java 8 and offers more than a handful of new options for optimally designing and implementing unit tests. These include, among others, the assignment of descriptive display names and the timely execution of individual test steps. In the second part of his presentation, Tim Riemer introduced TestContainers, a library that enables Docker containers (such as databases) to be initialized, started, and stopped using a JUnit test.

JUnit5 and TestContainers will soon be included in the WidasConcepts technology stack.

The time between the lectures was used to gather information on the companies that made presentations at various stalls or to take part in applicable competitions. With 10 out of 15 precise programming languages, Anke was able to impressively prove her profound knowledge in software development 😊

The day ended with one or the other shop talk with colleagues from past projects, where one thing became clear:

The Java world never stands still & after JFS is before JFS!
