Overcoming Challenges Involved in API Testing

By CIOReview | Thursday, December 22, 2016

Application Program Interface (API) is a set of tools, protocols, programs and standards developed for a specific purpose––building software applications. In modern enterprises, API testing is a commonly deployed procedure that occurs prior to the GUI testing scenario––which usually involves a series of automated and manual procedures. The initial part of API testing involves the task of configuring the database and server with respect to the application’s requirements. Once an ideal API testing environment is set up, an API call can be made to ensure stability before proceeding for further testing. But, to ensure optimal performance of the APIs, it is also very crucial to test its integrated components and features at the code level.

Although most procedures are complex in nature, identifying the common challenges and adopting a streamlined approach effectively helps enterprises achieve success in API testing; also meeting time constraints and boosting productivity.

As numerous organizations across the globe have already deployed API testing methodologies, considering the below mentioned key points can be helpful to tackle the challenges involved.

Deployment of Suitable Test Techniques

Technically, the gist of an ideal API testing strategy lies in its efficiency. Implementing techniques such as equivalence classes, error guessing and boundary value analysis will help API testing teams achieve efficiency in code coverage­­––improving the entire testing cycle.

Selecting an Appropriate Testing Framework

To inject stability into the entire testing scenario, the task of choosing a suitable testing framework is crucial. An ideal testing framework will enhance the functionality of GUI tests, enabling efficient integration between the GUI and API functions. The framework will also include management tools, reporting tools and API libraries.

Design Successful Test Cases

Designing test cases with an aim to improve the end-user experience will directly help to produce better outcomes. Implementing a successful test case design involves the need to ensure full functionality of the system and how it will be effectively utilized by the end-user.

Managing Timeouts and Other Errors in Testing

While executing the process of API testing, timeouts and several other kinds of errors may occur. These errors can be effectively managed by deploying a highly efficient exception-handling mechanism. Furthermore, to manage the developed scripts, splitting the test data into dynamic and static states is always considered as the best strategy that works in a streamlined manner.

Allowing Teams to Analyze APIs

To stage a successful API testing, providing the API teams with ample amount of time to analyze and understand the functionality of API is always a crucial step.

In an extremely agile business environment, an extra effort to improve the API testing process leads to an application free from all kinds of errors. It is also very crucial to ensure that all the data passes only through the predefined API testing scenario that helps to inject the desired level of security, certification and compliance. Moreover, ensuring that all the business critical rules are being administered at the API tier provides additional time to test the overall user-experience. In a technology-driven era where new businesses emerge with numerous applications, ensuring full functionality of APIs while resolving the underlying issues paves a productive path towards future expansion.
