APIs are the basis of modern software development, more and more teams everyday moves away from monolithic applications and begin adopting a micro service based approach for their software development.

Customized API for small business applications

Every application you build today relies on APIs. Creating your own RESTful API can be a great way to build a business around data or you’ve collected or providing. It makes you application flexible, modern and can interchange data or service with other applications. That means it’s crucial to thoroughly verify APIs before rolling out the product to the client or end-users.

Why perform API testing?

Today more and more companies are leaning towards DevOps, Continuous Integration (CI), and Continuous Deployment (CD), therefore testing is an essential of the development. As part of your organizations testing strategy, API testing should be done using various automation tools, specially using AI and machine learning technologies.

To reduce the complexity of API testing, some vendors have created tools that utilizes AI to convert manual UI tests into API tests. Our team can help you to configure these tools that usually act like sniffers, using machine learning to automatically find patterns and connect relationships among different services as users interact with the applications.

API Testing Approaches and Tools

API testing is a set of quality assurance plans that include sending calls to the API, getting output, and validating the system’s response against the defined input parameters, in particular, the accuracy of data and data’s format, HTTP status codes, and error codes. The current popular tools for testing APIs include Postman, Rest Assured, jMeter, and others.

Types of API tests

Here we have listed the typical types of API tests that Dynathrone team of testers usually preform for our clients in Toronto and Canada. The API tesing is ofcourse part of the testing plan and and various depending on the nature of each project.

*API Test type*	*Description*
Validation testing	Validation (or verification) testing is one of the last steps in the development process, but it is one of the more important test. It verifies the processes to check whether the API meets the specifications and that it fulfills its intended purpose. It includes a set of questions about the product, its behavior and efficiency and basically running everything against the initial requirements.
Functional testing	Functional testing is the assessment of specific functions within the code. It makes sure the API actually works within expected parameters, meaning it: returns the desired output for a given input; handles errors when the results are outside of the expected parameters. A typical functional testing types is Positive/Negative testing. Negative testing checks how an API responds to every possible kind of wrong input, while positive testing verifies the correct functioning of the API when the input conforms to the norm.
Performance testing	To ensure the API can handle the expected load, we validate its functionality and performance by artificially creating and simulating API calls.
Load testing	Load testing is to measure where the limit of system performance under high load lies. It measures response times, throughput, server conditions, and others while the number of calls are being constantly increased
Soak testing	Load tests that runs over a long period of time can reveal system instabilities like memory leaks.
Stress testing	Stressing the application by increasing the count of virtual users to find the point at which the API starts throwing errors, slows down, or stops responding.
Spike testing	Creating a sudden spike of users will test whether the API is able to stabilize and return to normal function.
Scalability testing	To measure that the system performance scales according to the changing load by increasing the number of incoming requests and monitoring whether it causes a proportional increase in response time.
Peak testing	Similar to soak testing, here you subject your API to the heaviest load while reducing the time of the attack.
User Interface testing	UI testing is more specific test of the user interface for the API and its constituent parts. Whether the interface is graphical or depends upon command-line endpoint calls or how the user or developer experience is measured .
Security testing	It validates whether security requirements are fulfilled which includes authentication, permissions, and access controls. It also includes topics such as authentication type, sensitive data encryption. resource authorization, etc.
Fuzz testing	As part of security audit we forcibly input massive amounts of random data, it tests how well the API survive or doesn’t show negative behavior like a forced crash or overflow.
Penetration testing	Another security test is penetration testing. The penetration testing, certain API functions, resources, processes, or the entire API is under attack from the outside to determine whether the threat vector is reached.
Reliability testing	Test the reliability of interfacing between internal or third-party services by simulating disconnection on various devices and how well
Integration testing	Test the integration between internal or third-party services by testing communication between APIs to ensure they properly integrate to each other
Interoperability and WS Compliance Testing	This test is planned only when using SOAP APIs in the enterprise environment to ensure the API complies and conform to the Web Services Interoperability profiles.
