Why Do you Need Software API Testing?

Besides offering a language-independent mode of exchanging data, API testing offers several other benefits. You need it for:

Improved Performance

API testing allows you to evaluate critical performance metrics such as response times, throughput, and scalability under varying load conditions. Based on this analysis, you can optimize for better results.

Increased Security

API testing includes rigorous security testing to identify and mitigate vulnerabilities such as authorization flaws, injection attacks, data leaks, and other potential security risks.

Seamless Integration with GUI

API testing ensures that the API seamlessly integrates and exchanges data with external components like external services (for example payment gateways). This fosters seamless end-to-end functionality.

Enhanced User Experience

Comprehensive API testing ensures that end-users have a positive interaction with the application, enhancing overall customer satisfaction and loyalty.

Our Approaches to Software API Testing

We offer versatile testing methodologies, spanning both manual and automation-based methods.

Manual Approach

  • Test Scenario Creation: Experts at our API testing company analyze your existing interfaces and testing objectives to create diverse test cases. They identify critical paths, edge cases, and potential failure points to ensure comprehensive test coverage.
  • Test Execution: They execute the test cases by sending requests to the API endpoints and observing the responses to verify that the API behaves as expected.
  • Error Handling: Testers intentionally introduce errors or invalid inputs to verify that the API returns appropriate error codes, error messages, and error responses.

Automation-Based Approach

  • Test Case Design: API testers design test cases based on requirements, specifications, and use cases.
  • Automation Script Development: They develop automated test scripts that interact with API endpoints programmatically (send requests and validate responses).
  • Test Execution: These test scripts are executed automatically by the chosen testing tool or framework, and the results are logged in real time.
  • Error Handling and Reporting: Automated API testing scripts include error-handling mechanisms.

Turning your API Testing Challenges into Opportunities

As a leading API testing company, we understand the intricacies of API testing and its associated challenges. Our expertise enables us to efficiently address them and drive your development and quality assurance processes forward.

Data Sensitivity Concerns

  • Your Challenge: Software API testing often requires sensitive data, making it vulnerable to getting exposed during the process.
  • Our Solutions: Our testing experts execute the process in strictly controlled environments having mock servers and stubs to simulate real-world scenarios. This prevents sensitive data from getting exposed to external environments.

Authentication and Authorization

  • Your Challenge: Authentication and authorization testing is a complex process requiring extensive token management, credential handling, and access level definition.
  • Our Solutions: Our API testing services automate token generation and use multiple test accounts with varying access to gauge a comprehensive understanding of authorization workflows. This allows you to benefit from increased security.

Dependency on External Services

  • Your Challenge: Modern APIs often depend on multiple external services (payment gateways, geolocation services, email services, etc) that may/may not be available or reliable in your testing environment.
  • Our solution: We follow a human-supervised, AI-powered automation testing approach that allows you to set up realistic testing environments that replicate the behavior of external services. This mock-up eliminates errors associated with 100% manual or automated test configurations.

In our view, automating a substantial portion of API testing is highly advantageous. Automated testing not only enhances accuracy and security but also expedites the testing process. However, it's essential to emphasize the importance of human insight and supervision. Human involvement ensures that test parameters and environments accurately represent real-world scenarios, thus bolstering the reliability and effectiveness of API testing. This is why API testers at SunTec follow a humans-in-the-loop approach to give you the best of both worlds.

While both focus on enhancing your software, they serve different purposes in the development process. API testing focuses on testing the functionality, reliability, and performance of the backend services or APIs directly. It involves sending requests to the API endpoints and validating the responses returned by the server.

Conversely, UI testing involves testing the graphical user interface (GUI) of an application to ensure that it functions correctly from the user's perspective. It replicates user interactions, such as clicking buttons, entering data into forms, and navigating through screens, to verify that the UI behaves as expected.
