View webinar: http://www.eurostarconferences.com/community/member/webinar-archive/webinar-81-api-testing-the-heart-of-functional-testing An API, or Application Programming Interface, is a collection of functions that provide much of the functional capabilities in complex software systems. Most customers are accustomed to interacting with a graphical user interface on the computer. But, many customers do not realize the much of the functionality of a program comes from APIs in the operating system or program's dynamic-link libraries (DLL). So, if the business logic or core functionality is exposed via an API call then and if we want to find functional bugs sooner than API testing may be an approach that provides additional value in your overall test strategy. Additionally, API testing can start even before the user interface is complete so functional capabilities can be tested while designers are hashing out the "look and feel." API testing will not replace testing through the user interface, but it can augment your test strategy and provide a solid foundation of automated tests that increase your confidence in the functional quality of your product.

As more and more apps are being assembled from a rapidly expanding array of microservices, APIs are the key to accessing these new architectures. That new feature you’re working on will often rely on upstream services that can only be accessed via APIs - so to test the functionality of the new component you’ll need to simulate those services. While APIs are the backbone of the websites and apps we rely on today, automated testing of them is only starting to grow. Join Patrick Poulin, CEO of API Fortress, as he provides an introduction to API testing, the best ways to test your own APIs using popular tools available today, and demonstrates the orchestration of API tests and Sauce Labs tests as part of a Jenkins build process. Key takeaways: -Clearly understand what API testing means. -Learn about best practices. -See demonstrations of popular testing tools. -See API and UI/UX testing implemented as part of a Jenkins build.

As an organization grows, the body of code that needs to be regression tested constantly increases. However, to maintain high velocity and deliver new features, teams need to minimize the amount of manual regression testing. Eric Smith shares his lessons learned in automating RESTful API tests using JMeter, RSpec, and Spock. Gain insights into the pros and cons of each tool, take back practical knowledge about the tools available, and explore reasons why your shop should require RESTful automation as part of its acceptance test criteria. Many decisions must be made to automate API tests: choosing the platform; how to integrate with the current build and deploy process; and how to integrate with reporting tools to keep key stakeholders informed. Although the initial transition caused his teams to bend their traditional roles, Eric says that ultimately the team became more cross-functionally aligned and developed a greater sense of ownership for delivering a quality product.

This our Twelfth semiannual report on the global Cryptocurrency mining industry. Bitcoin is the world’s largest special purpose supercomputer. And it is globally decentralized. Millions of nodes all run the same open-source code to secure the Bitcoin network, create value, and put new transactions onto the distributed ledger. The latest Top500 list has just been announced at the ISC 2024 conference in Hamburg, and once again the Frontier supercomputer with 1.2 Exaflops peak performance is number one on the list. If assigned to SHA-256 hashing, Frontier would provide only the equivalent hash rate of about three cabinets of the latest high-end Bitcoin mining systems, costing less than 0.1% of Frontier’s cost. Michael Saylor, Chairman of MicroStrategy, has pointed out that GPUs are two orders of magnitude slower than the 5-nanometer technology of custom ASICs used for Bitcoin mining today. He makes the point that the Bitcoin network is unassailable by all of the hyperscale computing resources combined in AWS, Google, and Microsoft Azure cloud data centers today.
