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.
Software testing is fueling the IT sector forward by scaling up the test process and continuous product delivery. Currently, this profession is in huge demand, as it needs certified testers with expertise in automation testing. When it comes to outsourcing software testing jobs, whether it’s an IT company or an individual customer, they all look for accredited professionals. That’s why having an software testing certification has become the need of the hour for the folks interested in the test automation field. A well-known certificate issued by an authorized institute kind vouches that the certificate holder is skilled in a specific technology.
