People love to watch, read and interact with quality content — especially video content. Whether it is sports, news, TV shows, or videos captured on smartphones, people crave digital content. The emergence of OTT platforms has already shaped the way people consume content. Viewers can now enjoy their favorite shows whenever they want rather than at pre-set times. Thus, the OTT platform’s concept of viewing anything, anytime, anywhere has hit the right chord.
JUnit is one of the most popular unit testing frameworks in the Java ecosystem. The JUnit 5 version (also known as Jupiter) contains many exciting innovations, including support for new features in Java 8 and above. However, many developers still prefer to use the JUnit 4 framework since certain features like parallel execution with JUnit 5 are still in the experimental phase.
API (Application Programming Interface) is a set of definitions and protocols for building and integrating applications. It’s occasionally referred to as a contract between an information provider and an information user establishing the content required from the consumer and the content needed by the producer.
