APIs, or Application Programming Interfaces, are the connecting tissue between different systems or layers of an application. Applications often have three layers: a data layer, a service (API) layer, and a presentation (UI) layer. The API layer contains the business logic of an application - the rules of how users can interact with services, data, or functions of the app. Because the API or service layer directly touches both the data layer and the presentation layer, it presents the sweet spot of continous testing for QA and Development teams.

While there are many aspects of API testing, it generally consists of make requests to a single or sometimes multiple API endpoints and validate the response - whether for performance, security, functional correctness, or just a status check. While UI testing may focus on validating the look and feel of a web interface or that a particular payment button works - API testing puts much more emphasis on the testing of business logic, data responses and security, and performance bottlenecks.

Whether you’re building an API or what APIs plug into, determining and executing all of the necessary test cases can be a complex task. Digital Point Technologies Inc's unique approach to API testing will save you time, money and the tedium of manual regression testing, addressing the overall architecture while using the best testing tools and testing approaches to focus on functional, inter-operational, performance and security testing.

Organizations have adopted modern architecture involving Cloud services and Mobile, and the result we see is a large composite system that sits behind these simple-looking applications. The content of the message layer and business logic is very critical to the successful operation of these applications. With the architecture following certain protocols, such as XML, SOAP, REST and others, the big question becomes – how to validate our Business Applications.

Digital Point automation approach

One of the effective approaches we are constantly using is keyword-driven testing (KDT). This approach covers hundreds of test cases in long-term projects with complex business logic.

Benefits of test automation

Cut overall QA costs

Costs are reduced as the QA team shrinks due to the manual work replacement.
Time-to-market

Overall testing time decreases as automated tests can be run quickly, anywhere and are conditionally free.
Improve product quality

Automated tests eliminate possible human mistakes – automation does not ignore or overlook the things that a real person can.
Optimize testing activities

Automated tests release tester's time, thus allowing to focus on testing extra functionality where manual tests are required.
Increase productivity

Automation can increase productivity by reducing the time required to perform repetitive tasks.
Better test coverage

Test automation, unlike manual testing, provides much greater test coverage when it comes to processing large data volumes.
