APIs, or Application Program Interfaces, have become an integral way of connecting people, their devices, and the information they need. They allow different applications to interact with one another and transfer data back and forth—they’re the main vein for app integrations and single sign-on functionality, and are essential to the rise of the Internet of Things (IoT). There are plenty of benefits and advantages to API testing, but the high-level ones that matter most to engineering teams and the larger business are improved test cycle coverage, better Agile processes between dev and QA teams, huge time savings, and the ability to test the application in any core language.
