This instructor-led, live training in Bratislava is designed for anyone interested in learning Java for the purpose of test automation. It is a streamlined, intensive course with plenty of hands-on exercises to get participants ramped up quickly with the essential programming skills needed to apply to software automation testing. The focus is on the Java fundamentals which can be directly and immediately applied to test automation.

This course does not cover in depth test automation frameworks such as Selenium. It also bypasses the conventional "Hello World" approach to learning Java, as this is not a course on application development. This course is squarely aimed at getting participants up and running quickly with test automation. If you are already versed in Java and wish to get straight into testing with Selenium, please check out: Introduction to Selenium (https://www.nobleprog.com/introduction-selenium-training).

Participants will gain a thorough understanding of the specific use cases for key Java concepts, the common challenges associated with them, and the role of application modeling. The course also covers fundamental knowledge of the Java standard library functions. It is required that participants are familiar with an integrated development environment (IDE) such as Eclipse or NetBeans for building Java applications. Please note that this training does not cover user interface design.

Even seasoned Java developers often do not fully master the diverse security services provided by Java, nor are they always aware of the vulnerabilities pertinent to web applications built in Java.

In addition to introducing the security components of Standard Java Edition, this course addresses security concerns within Java Enterprise Edition (JEE) and web services. The discussion of specific services is grounded in the fundamentals of cryptography and secure communication. Various exercises focus on declarative and programmatic security techniques in JEE, while both transport-layer and end-to-end security for web services are examined. Participants can gain hands-on experience with the discussed APIs and tools through several practical exercises.

The course also covers and explains the most common and severe programming flaws associated with the Java language and platform, as well as web-related vulnerabilities. Beyond typical bugs made by Java developers, the security vulnerabilities introduced encompass both language-specific issues and problems arising from the runtime environment. All vulnerabilities and relevant attacks are demonstrated through easy-to-understand exercises, followed by recommended coding guidelines and possible mitigation techniques.
