API Testing – Introduction

API Testing is one of the major software testing automation tools used for testing the APIs directly according to the specific functionalities and features like reliability, performance, security, and integrations. API testing validates the logic of the build architecture faster and efficiently. It is performed in the business layer that is the most important layer of API for testing the logical processing to carry out the transactions between the user interface and database layer. Learn the best API Testing Training in Chennai at SLA to perform the automation testing on APIs efficiently.

The learning benefits of API Testing

The learning of the API Testing Course in Chennai is helpful for the learners to perform automation testing on APIs with the following features.

  • Language Independent: Data is transferred through JSON and XML formats and it can be used for automation testing. These XML and JSON are typically structured data that make the validation fast and stable. There are numerous built-in libraries in API Testing software for supporting the data comparison using XML and JSON formats.
  • GUI-Independent: API Testing software will be performed in the application of GUI (Graphical User Interface) testing. It is used to increase team productivity through the core functionalities of API Testing simplify the detection of small errors and evaluates them for building strength.
  • Increased Test Coverage: Most of the APIs and web services have specifications that allow the tester to generate automation tests with the highest coverage and it contains functional testing and non-functional testing.
  • Faster Releases: API Testing is used to test the applications faster and it nearly saves eight hours than any other UI Testing and it allows the software development team to deploy the product application before the due time.

We train the interested students to be well-versed with automation testing through our API Testing Training in Chennai and make them perform in the companies as per the requirements. The following API testing types will be practiced in our API Testing Training Center in Chennai with Hands-on Exposure.
