API and Microservices Testing

Optimize your API & Microservices Journey with Cutting-Edge Testing

Talk to our Experts

Businesses rely on APIs and microservices to offer flexible, scalable and interconnected applications. Testing at the API and microservices level helps recognize the potential vulnerabilities, confirm data consistency, and validate the interaction between various services. This offers overall reliability and performance of the software ecosystem. Our services are customized to meet these complex testing needs. Using a comprehensive approach, we assess API endpoints and microservices functionalities and validate data flow to check and address issues before they impact the user experience.

API Testing Challenges and Solutions

Challenges
  • Interoperability issues due to regular interaction with various platforms, languages, and protocols
  • Validate and handling different standards of data formats
  • Ensuring consistent responses across frequent updates or changes  
  • Maintaining numerous APIs with various parameters for reusable data
  • Aggregation and integration of all individual products or services  
  • Architectural complexities due to diverse moving parts 
Solutions
  • Comprehensive test suite covering various scenarios
  •  Compatibility testing with different platforms and versions
  • Leverage tools for automated validation against industry standards
  • Employ versioning strategies to maintain backward compatibility
  • Implement automated regression testing to catch inconsistencies early
  • Capture and store data into a model to understand the connections between API call requests and responses

Our API and Microservices Testing Services

Unit Testing

Use the smallest piece of testable software to check if the application is behaving as expected.

Integration Testing

Use actual internal models involved like API resources, service layer, Message queues, etc. to check if they collaborate as intended.

End-to-End Testing

Ensure all components of a distributed system work seamlessly to deliver high quality applications.

Contract Testing

Verifying that the results achieved meet the contract expected by the consuming service.

Performance Testing

Do performance testing at two levels – Microservice Level (for each microservice when deployed), and System Level (When all microservices are deployed to work together).

Component Testing

Use standard API testing tools like SoapUI, Rest-assured, Ready API, and HTTP client to Isolate the components and thoroughly check their performance as an acceptance test.

    FAQ's

    What is API service testing?
    • API service testing verifies an API’s functionality, performance, security, and reliability. It ensures that APIs return the correct output, handle different requests properly, and work seamlessly with multiple systems. API testing detects issues early and ensures smooth integration between applications.

    What are web services in API testing?
    • Web services in API testing refer to software components that allow communication between applications over a network. They use protocols like SOAP or REST to exchange data. Testing web services ensures they function correctly, return expected responses, and handle errors efficiently in different scenarios.

    Which tool is used to test web API services?
    • Popular tools for testing web API services include Postman, SoapUI, RestAssured, and JMeter. These tools help validate API functionality, check response accuracy, assess security, and measure performance under various conditions.

    What are the three types of API testing?
    • The three main types of API testing are functional testing, performance testing, and security testing. Functional testing checks if the API works as expected, performance testing evaluates response times and scalability, and security testing ensures data protection and prevents unauthorized access.

    When to automate web services testing?
    • Automate web services testing when APIs require frequent regression testing, handle large data sets, or support continuous integration. Automation is ideal for repetitive test cases, improving efficiency, accuracy, and test coverage while reducing manual effort.
