JUnit Framework, the unit test framework for java applications has an important role in test driven development. JUnit is an open source framework used for unit tests of small and large units of code. JUnit can be integrated with Selenium to make the testing process easy and smooth. JUnit annotations can be used in selenium scripts. Similarly, Junit methods and assertions can be used to enhance the performance of selenium.
When more and more selenium experts started using JUnit, its popularity increased and the expertise in JUnit has become an added advantage for selenium experts. This increased the demand for JUnit framework tutorials.
There are many JUnit framework tutorials and most of them are online tutorials. Usually, the online trainers will provide JUnit framework videos as study material. These videos will discuss unit test and also depict the entire process of testing step by step. Simple narrations and supporting infographics will make the learning process easy and interesting. Besides, the professional trainers provide chat facility for the trainees to interact with them. Trainees can clear their doubts through this chat facility. Further, it will give them a feeling of learning from an in-class tutorial.
In all JUnit tutorials, there is a live project session. This session will be at the end of the course and is meant for providing practical experience to the trainees. Besides, this session will help students familiarized themselves with the real time problems and issues that may come up in future when they have to work with live projects as a part of their career.
Trainers will give importance to JUnit annotations and JUnit methods as they play the major role in selenium testing. However, JUnit can be used independently for unit tests too.
When different trainers offer courses, the course content may differ slightly based on the priorities of the trainers. Most of the professional trainers are offering the syllabus in the following pattern.
