Students who attend Unit Testing Essentials using JUnit and EasyMock will leave the course armed with the skills they require to develop solid Java programs, using sound coding testing techniques and best coding practices. This course quickly introduces developers to the features of JUnit and educates them regarding JUnit’s strengths and weaknesses. JUnit and EasyMock make it possible to write higher-quality Java code. These powerful tools are designed to support robust, predictable and automated testing development in the Java enterprise application arena. This course includes coverage of many of the essential JUnit capabilities, and can be tailored to focus exactly on the areas that you are interested in.

  • The following JUnit-based testing frameworks are examined: JUnite, EasyMock, and PowerMock

Who Can Benefit

This is an intermediate-to-advanced level Java course, designed for developers who wish to get up and running on test-driven development immediately. Attendees should be familiar with Java and object-oriented technologies. Real world programming experience is a must.

Course Details

Experiential Learning – Course Structure

Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review. This workshop is about 50% hands-on lab and 50% lecture. Multiple complete “mini-projects” are laced throughout the course, designed to reinforce fundamental skills and concepts learned in the lessons, all working in the JUnit environment. Because these lessons, labs and projects are presented in a building block fashion, students will gain a solid understanding of not only the core concepts, but also how all the pieces fit together in a complete application.

The class was good, but at times the pace did seem a bit fast to actually try to remember some of the information.

Both course material and instructor demonstrated a sound foundation on Maximo material

it was good and very informative. Instructure covered everything in detail.

The class was very vast paced however the teacher was very good at checking in on us while giving us time to complete the labs.

Course trainer was excellent, content was well organized. However, labs should be instructor lead versus on your own. Much time is wasted for newbees in getting acclimated to tool set, AWS environment, navigating and setting up things to complete tasks. This was my third class and I was barely able to finish most of the labs. (The first 2 classes I only finished one lab exercise for the 2 together.)
