How to Solve Business-Critical Challenges With API Testing?

In the era of connectivity and the digital landscape, Application Programming Interfaces (APIs) are essential in presenting an intuitive user experience across software apps. APIs are necessary for seamless connection between different systems for smooth data exchange. Businesses rely intensely upon API functionality, and that's why ensuring their reliability, functionality, and security is of utmost importance.

The developers can quickly detect errors and bugs through API testing before it impacts the business operation, customer experience, and productivity. In this blog, our experts will discuss what API testing is and how businesses can easily resolve critical challenges through rigorous API testing.

Everything you should know about API Testing

 An Application Programming Interface or API is a code block enabling communication between two software programs. The software contains several layers, including the API layer, which provides business logic in the software.

API Testing evaluates the functioning of every API within the software system. It checks all APIs' overall functionality, performance, dependability, and security and confirms that they appear to work as expected.  

The testing for API is done on the API code, or it is a part of integration testing. It is often confused with user interface testing, which focuses on validating the application's look and feel from the user's point of view. However, API Testing prioritizes and examines the application's business logic, security, and data responses.

Types of API Testing

Here are some different types of tests to determine API's performance and operational efficiency:

●      Functional Testing - The functional test emphasizes verifying the software development system against functional requirements. A quality assurance tester provides appropriate input parameters in XML or JSON payload and then verifies the output against the functional requirements to test each API function.

●      Validation Testing - Validation testing helps determine API usability as a product, transactional behaviour, and operational efficiency.

●      Load Testing - API load tests evaluate the performance of API under a certain load. It examines the operations of API as to how well it behaves with multiple users simultaneously.

●      Reliability Testing - Reliability testing ensures API testing can provide consistent results and the connection between two software is reliable.

●      Security Testing - Security testing assists in validating encryption, access control design, and other security aspects.

●      Penetration Testing - Penetration testing helps examine the security where a person with limited knowledge about the API attacks the system.

●      Fuzz Testing - Fuzz testing helps to reveal vulnerabilities and defects by forcibly providing huge amounts of random data into the system.

●      Unit Testing - API Unit testing includes testing single endpoints with a single request.

●      Integration Testing - Integration tests help in analyzing how API integrates the software.

How API Testing Helps Businesses Excel?

APIs are the backbone of modern system softwares because they help establish connections between various applications, databases, and third-party softwares. When the APIs function seamlessly, it becomes easy to handle business operations efficiently. Here is how API testing helps businesses:

 ●      Glitches, slow response times, and errors in API functionality can lead to poor customer experience. API testing can help to identify usability issues and resolve them easily to deliver a robust and reliable platform.

●      APIs transmit sensitive information, like user credentials and financial and personal details. Testing can assist in evaluating the security, validating the data encryption mechanisms, and checking for security breaches. 

●      APIs are building blocks for microservices and connecting different components. The API testing aims to make changes during development to ensure modifications do not break the API's existing functionality.

●      API testing helps businesses verify the compatibility and interoperability of APIs across different systems because compatibility issues, versions mismatch, and integration failures can disrupt business operations.

Different Business Challenges That Can Be Resolved By API Testing

API testing helps to mitigate risks, ensure system stability, and deliver quality software solutions. Here is a list of different business challenges that API testing handles:

●     Accessibility to the application without user interface

API testing can be done without navigating the user interface. It becomes easier for businesses, especially quality assurance engineers/meters, to run API tests. It provides quality assurance engineers with an early understanding of defects and errors in the software application so that developers can resolve the issues before they change the graphical user interface.

●     API testing examines the core functionality.

When businesses evaluate code-level functionality, they must execute an early evaluation process. It is because code-level functionality provides overall build strength before you run a GUI test. It uncovers small errors and loopholes that can persist and become larger problems during GUI testing. On the other hand, core functionality enables testing with development, enabling communication and greater collaboration between businesses and customers.

●     Time Factor

API is less time-consuming than GUI. It needs the polling of web page elements that, in turn, slow down the testing process at once. However, API testing produces speedy work and enables fast delivery. Due to lesser code and better test coverage, API becomes time effective for business organizations. 

●     Independent of programming language

An API test requires exchanging data by using XML or JSON. These are the markup languages required during API testing. These exchange methods are completely language-independent. It means you can select any core language while seeking automated testing services for your software application. Thus, it becomes easier to run API tests because of their independence from the programming language.

●     Easy integration

API testing enables highly integrable tests. You can easily integrate functional GUI tests with API tests. Nonetheless, this is especially beneficial if businesses plan to perform functional GUI after API testing. For instance, easy integration will facilitate the creation of new users within the application. This can be done before the businesses start a GUI test.

Wrapping up

APIs have become critical to almost all business organizations as we have become more interconnected. With good and regular API testing, every business can give a user-friendly experience to its customers. Every engineer, testing provider and software company must effectively process an API testing strategy and build an enhanced customer experience.
