This instructor-led, live training in Jakarta 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).

During the training participant will know the specific use of selected issues, the basic problems encountered when using them, and the role of the application model. The training also includes a basic knowledge of the language standard library functions. Training requires knowledge of the development environment IDE used to build Java applications (e.g.. Eclipse, Netbeans). Training does not include a user interface issues.

Even experienced Java programmers are not mastering by all means the various security services offered by Java, and are likewise not aware of the different vulnerabilities that are relevant for web applications written in Java.

The course – besides introducing security components of Standard Java Edition – deals with security issues of Java Enterprise Edition (JEE) and web services. Discussion of specific services is preceded with the foundations of cryptography and secure communication. Various exercises deal with declarative and programmatic security techniques in JEE, while both transport-layer and end-to-end security of web services is discussed. The use of all components is presented through several practical exercises, where participants can try out the discussed APIs and tools for themselves.

The course also goes through and explains the most frequent and severe programming flaws of the Java language and platform and web-related vulnerabilities. Besides the typical bugs committed by Java programmers, the introduced security vulnerabilities cover both language-specific issues and problems stemming from the runtime environment. All vulnerabilities and the relevant attacks are demonstrated through easy-to-understand exercises, followed by the recommended coding guidelines and the possible mitigation techniques.
