Key Benefits Of API Testing For Your Business

Companies routinely observe APIs during production to check that the live API endpoints are up, running, and delivering the anticipated data to the user. As a result, testing teams will be notified if something goes improper and will be able to fix any issues before users realize anything is wrong.

But what if clients discover problems with the API before you do? What if the problem is more severe than just being slow?

API testing is something that smart companies do before deploying changes to production, and you should do the same. To assure that the software application satisfies requirements, APIs must be estimated in both staging and development environments.

What is API testing? What kinds of API testing should QA UI teams perform? What are the differences between API testing and GUI testing? What advantages does API testing have over UI testing?

Let’s look at how your team may profit from API testing by improving the way you handle your testing strategy.

What Is API Testing and How Does It Work?

API testing is a form of software testing that verifies Application Programming Interfaces, or APIs as they are generally known. API testing assures that an application’s efficiency, usability, security, and dependability are all up to par. When utilizing API testing tools to perform test cases, QA teams get the benefits of API automation.

So, what’s the link between API testing and UI testing? API testing advantages concentrate on the business logic layer of the software’s design, whereas UI testing advantages focus on the look and feel of the user interface. In other terms, the advantage of API testing over UI testing is that it verifies the validity of an API from all angles, not only from the user’s view.

The Different Types of API Testing

The three main kinds of API testing that our experts use with our customers and recommend to others are listed below.

Testing for Functionality

Functional tests assure that the software system satisfies the functional requirements. A QA tester gives proper input parameters in XML or JSON payload to test every function of the API, then examines the output against the functional requirements.

Testing for security

API security testing recognizes any risk, weakness, or danger that may exist inside the API. Security testing reveals any possible loopholes or API flaws that might lead to the loss of data, money, or reputation if utilized by an unauthorized user. After all, what good is API testing if it doesn’t defend you against malicious internal users or invading criminals?

Testing Under Load

API load tests assess how well an API performs under a given load and how well it behaves when certain users contact the system at the same time. API testing utilizes exact data and specific statistics to verify an API’s projected load.

Quality end-user experience is contingent upon testing API’s right from start. Try our services for successful end-to-end testing.

The Advantages of API Testing

These API testing advantages can enhance your product’s performance, client satisfaction, and security, depending on your project timeframe, integration requirements, and desired functionality:

  • Basic Functionality will be reviewed

Before performing GUI tests, testing an application’s code-level functionality allows an early assessment of its overall build robustness. GUI testing helps uncover tiny errors that might grow into major issues. Core access provides testing to run concurrently with development, enhancing communication and collaboration between the two teams. If you’re utilizing an offshore QA staff to test your APIs, this is a big plus.

  • Access Without a User Interface

Access to the program without a user interface or people to employ with the system is a significant advantage of API testing. To put it another way, QA testers can perform API tests without having to utilize the software application themselves. This is a huge advantage since it gives QA engineers early access to errors and mistakes, allowing developers to correct them before they affect the user interface.

  • Integration is straightforward using the GUI

API testing provides for highly integrable tests. This is particularly useful if you want to support your API testing with functional GUI testing. Easy integration, for instance, would provide new users to be created within the program earlier to the commencement of a GUI test.

  • Effectiveness of time in terms of task completion

One of the most important distinctions between API and GUI testing is that API testing takes significantly less time than functional GUI testing. GUI testing requires polling of web page elements, which may significantly slow down the testing method. And what is API testing best identified for? Its ability to give conclusions quickly!

  • Language-Independent

An API test shifts data using XML or JSON, as previously stated. These transfer modalities are completely language-agnostic, which suggests you may use any core language while watching for automated testing services for your app.

  • Test coverage improves

Automated API testing, unlike unit tests, has a broader reach. While unit tests are designed to concentrate on the limited functionality of components inside a single application, issues usually happen when one layer’s scope stops and the next starts.

Unit tests won’t catch these difficulties, but API-level tests are particularly designed to assure that all system elements work as they should. API testing reveals possible flaws in user interfaces, servers, and databases, occurring in higher software quality and enhanced user experiences.

  • Stability is tested more often

API interfaces are usually more stable than graphical user interfaces, which can alter to satisfy new requirements from users and stakeholders. APIs usually provide comprehensive documentation, and any modifications are noted in this documentation so that QA engineers can have their test suites up to date. Because of their intrinsic dependability, API tests are also simple to manage.

  • Cost savings

The cost-effectiveness advantage is linked to the preceding one. Automated API tests run faster, ending in more efficient resource utilization and cheaper total testing expenses.

Prior to any GUI testing, API tests may be performed as soon as the business logic is specified. API testing enables the QA team to identify and address issues before they become a production issue, reducing project expenses.

API Testing Is The Need Of Your Organization

Everyone thinks that the best way to ensure high software quality is through thorough testing. And, because it enables testing of the most essential business layer, automated API testing is significant in a well-designed QA approach. API testing also has a number of commercial benefits, including increased test coverage, faster outcomes, lower costs, and simpler maintenance.
