It takes a String value and a Object... values as arguments. The String value is used to set a description to the assertion. The Object... values are used to format the String value. The as() method returns an instance of AbstractAssert class. This instance is used to perform the assertion

While there is a huge demand and need to run Selenium Test Automation, the experts always suggest not to automate every possible test. Exhaustive Testing is not possible, and Automating everything is not sustainable.
Many theoretical descriptions explain the role of the Scrum Master as a vital member of the Scrum team. However, these descriptions do not provide an honest answer to the fundamental question: “What are the day-to-day activities of a Scrum Master?”

In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.
