API Testing

Application Programming Interfaces or APIs are what programmers utilize to connect to the other for facilitating the interaction of data between them. If an API doesn’t work exactly the way it is meant to, or if the effectiveness of an API is compromised, it can negatively impact the realization of business goals, user experience and productivity. When interacting with external systems, most businesses today, use enterprise-grade APIs to connect seamlessly with customers, partners and vendors.

API Testing Services

An effective and robust API testing process should encompass several types of tests. Thorough API testing ensures the performance, functionality, and security of APIs which translates to seamless business operations and an enhanced user experience. At RaagviTech, we also offer automated testing services to augment the efficiency and efficacy of your APIs. Listed below are some of the API testing services offered by RT:

Functional Testing

Functional testing is done to validate the full cycle functionality of your APIs and how they interact with external systems and processes.

Load Testing

API load testing ensures that your apps and their associated external interactions are able to perform effectively when put under stress owing to a large number of concurrent and sustained transactions.

Automated API Testing

We have the resources, technology, and tools to automate API transactions. This allows development teams to scale quickly while ensuring their APIs go through rigorous testing before production.

Security Testing

Security Testing ensures routine security checks like user authentication and access meet the predefined business requirements. Common security testing approaches include ethical hacking and fuzz testing.

Web UI Testing

Web UI testing ensures that the app’s functionality and user experience meets business requirements.

Runtime/Error Detection

This type of testing ensures that exceptions are logged and handled properly. This ensures that any resource leaks are identified and amended.

Validation Testing

Validation testing is to ensure all external interfaces (such as APIs) are working exactly as intended across the entire application. Validation testing typically includes a series of smaller tests such as unit testing, integration testing, system testing and user acceptance testing.

Interoperability & WS Compliance Testing

This type of testing is done to ensure that your SOAP APIs communicate with all other application components as intended.

API Testing Benefits

Ease of Access

API Testers can identify and fix defects and bugs before they are blown out of proportion.


API testing requires lesser coding when compared to other types of testing, which means your teams can go into production much faster.

Increased Security

Because API testing employs a unique set of conditions and input variables, it allows development teams to address common vulnerabilities while augment the security aspect of an application.

Language Independent

An API test typically involves exchange of data using JSON or XML. These interaction methods are intrinsically language-independent, which means you can make use of any coding language when you want to run automated testing for your software.

Simple GUI Integration

Web API testing can be integrated with other tests which means testing teams can easily connect GUI tests with the API testing process.

Faster than Functional GUI testing

Development teams can scale quickly and efficiently with API testing. Our test experts will tell you that literally thousands of API test cases can be executed within an hour. That’s a fraction of what it will take for a similar number of functional GUI tests to be executed.
