API Testing Services

We'll guide you through the key processes of API testing and show you how to implement software API testing in your company to enhance the development process and ensure product quality. 

API testing to smooth the development workflow
  • API Testing To Smooth The Development Workflow

    API testing allows us to test new features from the backend developers even before the UI is ready. Thus, API testing helps to identify and correct errors on the backend without the need to correct the consequences of these errors on the front end.

  • Achieve Software Reliability & Security With API Testing

    Usually, to check data accuracy, schema, data type, order, completeness, HTTP status codes, and error codes should be verified. This helps to identify and correct possible errors before operating the product. API software testing also aids in ensuring software security, allowing you to identify and fix potential errors while exchanging data between different system components. This may include input validation, SQL injection protection, access rights checking, API security techniques, etc. 

Our Approach

We perform API testing services on different devices, operating systems, and browsers. If any errors do happen, that might cause the program hacking. APIs are often complex, with many different parameters, endpoints, and possible responses that require special skills for testing. Luxe Quality helps companies build high-quality products by ensuring integrated APIs meet application functionality, reliability, performance, and security standards. 

API testing services based on testing types

We can offer a review of different types of API software testing to help you get more information and better understand how to test API effectively.

  • API performance Testing

    API performance testing, a core aspect of our API testing service, assesses the performance and consistency of an API under normal and high-load conditions, measuring its stability and speed through simulations. We use tools like Gatling, Jmeter, and K6 for this type of testing.

  • API security Testing

    Testers use API security testing methods to prevent potential attacks and malicious actions. QA performs unauthorized access to the server to ensure the protection of user information. For automation API testing, testers use tools such as Burp Suite, Acunetix, and Restler-Fuzzer.


  • API Integration testing

    API integration testing studies the relationship between different system modules. Productivity and the provision of quality services directly depend on effective integration. We use such tools as Postman, Runscope, Checkly, Karate, and others to implement these tasks.

  • API automation testing

    In automated API testing, we use test scripts to check the reliability and high functionality of the API application in the project. This type helps to significantly speed up the search for errors and improve the quality of the final product. Popular automated API testing tools include Postman, SoapUI, and Rest-Assured.

  • API manual testing

    Manual API testing is a process in which requests are sent manually by QA engineers, not scripts. Skilled testers write queries, integrate and test the API, and make necessary changes to address flaws.

  • API performance Testing

    API performance testing, a core aspect of our API testing service, assesses the performance and consistency of an API under normal and high-load conditions, measuring its stability and speed through simulations. We use tools like Gatling, Jmeter, and K6 for this type of testing.

    API Testing Benefits with Luxe Quality

    The benefits of API testing include identifying and rectifying interface errors that can adversely impact user experience and interactions with applications and services. Therefore, the following main advantages of using the software testing API should be listed.

    • Strong Protection icon

      Strong Protection

      It is vital to provide accurate data transfer in the appropriate format when interacting with external services through API. API testing ensures uninterrupted data communication, detects errors and enhances data security.

    • Core Access icon

      Core Access

      A convenient and exciting feature for API developers and testers is that API software testing allows access to the application without a user interface. That is, a permit is obtained from the kernel. This helps to save time as testing can be done simultaneously with development.

    • Time & cost effective icon

      Time & cost effective

      API testing saves developers time since testing can be started before the UI is implemented. It not only speeds up development workflows but also allows you to avoid future errors, significantly reducing development costs.

    API Testing Tools

    In our work, we use a comprehensive set of tools for API testing because each provides a range of capabilities necessary for testers.

    API Automation Testing Frameworks

    Frameworks are used during many development and testing stages because they significantly speed up and help the developer or tester. When it comes to automation API testing, there are numerous frameworks available, such as: Supertest, Testcafe, Pact, Playwright, Rest-assured, Karate, and Cypress, among others.

    Benefits of API Testing Services for Businesses  

    Based on your project timeline, integration needs, and desired features, these benefits can enhance your product outcomes, boost consumer engagement, and improve security: 

    • Improved API Quality 

      API testing enhances quality by identifying issues related to functionality, performance, security, and compliance. Through thorough testing, developers can ensure the API meets its requirements, integrates well with other systems, and provides a smooth user experience. 

    • Time Efficiency 

      API testing is quicker than conventional software testing methods due to automation. The structured design of APIs allows for easy automation of requests and responses, making automated tests straightforward to create and run, which saves significant time and effort compared to manual testing. 

    • Early Error Detection 

      Conducting API testing early in the software development process helps find potential problems before they spread within the application. This method helps spot integration issues and identify compatibility or communication errors at an early stage. 

    • Enhanced Security 

      Focused API testing can reveal and fix potential security vulnerabilities. It strengthens access controls, protects data integrity, and ensures compliance with security standards, ultimately boosting the overall security of your products. This includes identifying vulnerabilities, conducting penetration tests, ensuring data protection, and validating access controls. 

    • Reduced Complexity 

      Since API testing zeroes in on API functionalities and interactions, it is generally simpler than testing complex user interfaces (UIs). This focused approach allows for more efficient testing processes. 

    • Verification of Essential Functions 

      Addressing issues in core API functions early helps cut down on rework and lowers overall development costs. During testing, developers can ensure that critical features perform as expected, leading to a higher quality product.

    FAQ

    Automated testing should be used for powerful APIs that are too complex for manual testing.

    Any automated testing is sensitive to hardware (RAM, CPU), test architecture, environment settings, etc. At the same time, the choice of QA engineers for API testing should be approached very seriously because the low qualification of specialists will sufficiently reduce the testing of API efficiency.

    Automated API testing is usually better than manual testing because it allows faster and more efficient functionality testing and reduces the risk of human error. It also requires fewer resources, as it takes much less time to perform, but it demands high-skilled specialists.

    The choice depends on your requirements and goals. Each case should be considered individually. We use the following tools: Postman, SoapUI, Rest-Assured, Runscope, Checkly, Karate, etc.

    Challenges can range from parameter validation, response handling, and managing endpoints to simulating different conditions and handling unexpected results. Moreover, when transitioning to automation API testing, it's crucial to ensure that tests are not only fast but also accurate, adding another layer of complexity to the process.
