Are you a person with commendable knowledge in software applications? Are you skilled enough in API, Selenium, Testing tools and so on then logon to www.wisdomjobs.com. API Testing is a type of software testing that involves testing applications programming interfaces (API s) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance and security. It is a set of routines, protocols and tools for building software applications. It is now considered critical for automating testing because APIS now serve as the primary interface to application logic and became GUI tests are difficult to maintain with the shirt release cycles. So find your career in API Testing as software developer, engineer, Automation Analyst, API tester by looking into API Testing job interview question and answers given.
