Key Market Highlights:
API stands for Application Programming Interface, which is a programming interface that connects applications, a messaging system, or a database. API testing is a method used to ensure API endpoints and data-sharing functions are working as expected. Moreover, API testing prevents data corruption in transit and unexpected failures in database or endpoint connectivity. Furthermore, for efficient API testing, a proper testing strategy is necessary because it ensures that the crucial components required for specific API testing have been taken into consideration.
The application programming interface testing helps to confirm that the application’s APIs are interacting and saving data as intended. Further, it also tests each API and its functional area of the application impacted, and with every authentication, authorization, and encryption of data, API testing adds a layer of security testing, which is a crucial benefit of using API testing. Moreover, nowadays, data breaches have become very common, which can result from the interception or rerouting of messages and data.
Hence, to prevent such unauthorized users from accessing application data and restrict the cases of data breaches, API endpoint security testing is a must. Such relevant uses of these testing methods are acting as key factors propelling the API testing market during the forecast period.
Key players working in the market include IBM, Micro Focus (OpenText), SmartBear Software (Francisco Partners), Parasoft, Tricentis GmbH, Infosys, Runscope (BlazeMeter), Adobe, and Microsoft Corporation.
