API Testing & Its Benefits Linked to Development Process

API or Application Programming Interface can be defined as a set of procedures, tools, and protocols required to build software applications. Essentially, an API helps to specify how software components need to interact, which makes it highly important to run a test. The purpose of API testing is mainly to determine whether or not they are meeting the expectations related to performance, reliability, and security.

It won’t be wrong to tag APIs as the focal point of software development that works to connect and transfer data across distinct systems and applications. API testing can greatly enhance the efficiency of your already existing testing strategy and thereby fasten the delivery of software. Although many people confuse API testing with UI testing, it primarily highlights the use of software for sending API calls, drawing outputs and recording system responses.

What makes API Testing Essential for Business Processes?

Overall, APIs are known to raise the value of an application. This is why it is believed that to strengthen the establishment of business processes, APIs need to be correctly directed. They permit application content to be integrated efficiently, proving highly advantageous for enterprise operations.

For instance, if an API breaks due to a lack of error detection, the threat not only brings down a single application but might even impact the overall chain of business processes associated with it. Hence, API testing ensures in-depth investigation useful enough to safeguard the application and related business processes.

Another crucial role of API testing is linked to the investigation of applications having varied API functionalities to expose pivotal failures. The global API testing market is estimated to advance at a CAGR of over 19%, in terms of value, until 2024. Such growth can be attributed to the swelling demand for API monitoring concerned to the production industry, set to showcase higher statistics in the next five years.

Different Tests Related to API

  1. Functional Testing: By entering the correct input parameters under API testing it becomes quite convenient to test the functionalities. A response code can be acquired within a few milliseconds, thereby, making it quick and efficient.
  2. Security Testing: It becomes suitable to assess whether the data is coded in HTTP and required any form of authentication. This segment also focuses on penetration testing.
  3. Discovery Testing: With the incorporation of API testing, developers are benefited by identifying APIs around which the resources are not unprotected.
  4. Usability Testing: APIs can be easily hit on various platforms to test the usability of particular software.

API Testing & its Contribution to Development Process

To reap superior benefits of API testing, it is essential to include them in TDD or test-driven development process. This way the engineering teams are benefited in several ways which ultimately passes on as quality services impacting the customers.

Below mentioned are the three imperative ways through which your organization can benefit by amalgamating API tests with the development process:

Test Reporting

For holding up the quality of the product along with customer trust, it is necessary to assess all the bases concerned with possible software failures. The operation of API testing simultaneously with development can prove beneficial in revealing issues with the API, network, server, and other services. 

While the software rolls into the production phase, you will get an opportunity to create more tests to supply new and modified use cases. These tests in collaboration with the ones created during development work effectively to tackle almost any breakdown scenario. We can rate it as one of the significant benefits of API testing that lessens the count of support tickets to customer support and QA teams.

Test Caliber

It doesn’t make sense if you wait for the development process to finish to initiate your API tests. This way you’ll end up building them in a biased way leading to favorable test cases. As soon as the API is built, your focus rests on its performance and how to dodge cases of failure. 

Moreover, similar to iteration for software at the time of development, carrying out iteration on API tests would eventually make them highly comprehensive and stronger. As a result, the product quality will enhance in the long run with reduced chances of break down. 

Test Recycle

About the benefits of API testing, incorporating them in the initial stages will prove profitable as a majority of your tests are already managed. For example, Runscope permits you to reprocess the same tests through multiple environments and share tests.

Interestingly, your QA and dev teams create tests and can utilize them in staging environments. Later on, the DevOps teams can make use of the same tests to operate them on a schedule during production to administer those used cases. In short, reusing API tests during the development lifecycle supports collaboration within teams and delivers an accurate and extensive testing composition.

API Testing Merged with CI/CD & TDD

The act to integrate restful API testing with your development process can be managed in several different ways. For instance, numerous organizations include API tests within their continuous deployment (CD) and continuous integration (CI) processes clutched to trigger URLs or even direct plugin using an open-source automation server like Jenkins.

When an API test leads to failure at the time of CI or CD, the process comes to a halt indicating the API issue needs to be stabilized before the build is finished. The inclusion of API tests within this process offers greater assurance to both product and engineering teams mainly related to the coverage of all the bases before the product is released to the customers.

The benefits of API testing here also permits you to create tests specified to an API during the development process. This is almost similar to the process as to how we create other software in TDD. In simple words, test run new endpoints while they are being created during the development and later activate them to run within the CI/CD pipeline. To know more, you can get in touch with testers and developers at ImpactQA, who are skilled enough to impart necessary knowledge associated with API testing.

DevOps and the Future of QA

DevOps has been the talk of the town for some time now. The evolution and execution of the tools and procedures that facilitate its use are still growing. From insane articles like ‘DevOps will Kill QA’ to QA pundits coming out to the rescue of testers saying that ‘QA will be an integral part of DevOps’, the internet is full of information around DevOps and how it affects QA. Here is a quick look at what DevOps is all about and what it means to QA folks. In simple terms, DevOps is a methodology where Software Developers (Dev) collaborate with IT (Ops) that involves automation of software delivery and infrastructure. A decade ago the responsibility of QA was to find the bug and document it and that was it. This was a more casual approach.


Throwing the siloes to the pasture, DevOps seed time to market, and we can only hope that more and more enterprises adopt this in the coming decades. As more companies open their doors to collaboration, DevOps is also transforming testing methods and routines. The short development cycle normally associated with agile is also aiding in this mind shift. Therefore, DevOps and Agile can no longer be ignored as a passing trend.


Emergence of DevOps and Rise in Popularity
DevOps symbolizes a change in IT culture, concentrating on prompt IT service delivery through agile adoption, lean practices of a system-oriented approach. DevOps seeks to improve collaboration between development and operations teams. DevOps implementations make use of technology particularly test automation tools that can leverage more programmable and dynamic infrastructure from a life cycle perspective.

Over the years as CIOs and CTOs have been forced to bring down the ‘Cost of Quality’ and hence the focus of QA has shifted from a ‘casual’ approach to ‘a value driven’ approach. It’s now more about preventing defects than finding defects. The traditional waterfall model gave way to agile and now DevOps that allow frequent build and releases to production. As the digital transformation continues to accelerate into more industries, there is an increase in the adoption of agile and DevOps principles to ensure organizations can achieve the speed, quality, and scale needed to succeed. Security, performance, customer experience, and quality are more important than ever. At ImpactQA we have been seeing a growing demand for security, performance and UI/UX testing from our customers.

While organizations are struggling to find the answer to the question of how to achieve speed with the right level of quality, DevOps seems to have provided a solution. The shift-left approach would allow QA to be directly embedded into the sprint team or the scrum teams right from the inception where they’re involved from the word go and start writing the test cases as soon as a user story is complete. Also, a striking development in the approach to QA is the uptake of continuous monitoring with predictive analysis, along with the increased adoption of more cloud-based test environments. This shift-right approach would allow QA engineers to take product feedback from the end-users.  The Shift-Right approach to testing also empowers the test engineers to test more, test on-time and test late.

DevOps Statistics
For those who doubt, here are some additional DevOps statistics to take you over the top regarding enterprises that employ DevOps:

  • 38% report a top quality of code production
  • 63% experience upgrading in the quality of their software deployments
  • 63% release new software on a frequent basis
  • 55% noticed improved collaboration and assistance


What does this mean to QA Engineers?
 1.    As DevOps brings in more and more automation to the fore, the need for traditional manual QA will decline sharply. However, manual functional QA would not cease to exist.
2.    Not only would the QA need to understand the technology, but they will also need to understand the business and the end-customer. The end customer is a lot close to the business than ever before, with profound implications for the Quality Assurance and Testing functions.
3.    QA will have to change their mindset and start helping people instead of providing a transactional service to them. E.g. I would expect an automation QA to reach out to a developer (proactively) and say ‘Hey, for each UI element, you need to put an identifier and not have us rely, for example, on the X-Path will change. That will make tests more robust’.
4.    Automation is still evolving and there is a growing trend to higher levels of intelligent automation, largely driven by data-rich digital applications. QA engineers will have to be much closer to technology than they were a decade ago. In summary, DevOps testing has opened up an exciting and intriguing world of self-aware, self-remediating, analytics-driven automation and a paradigm shift in the QA mindset.


What Can We Expect for the Future of DevOps?
DevOps has come a long way. Initially, waterfall methodology was the way of the world. Then tester teams learned to shift left and test soon. They turn out to Agile. However, when DevOps accelerated, it scaled to fit the needs of bigger and bigger software testing teams. And now DevOps is growing and becoming smarter, thanks to new-edge technologies like artificial intelligence and machine learning. Teams today chase continuous testing for rapid releases and accelerated DevOps. The future of DevOps holds how DevOps will look entirely different in the coming years.


Change is exciting and the future of DevOps is bright. There is no shortage of it on the horizon for web and mobile app testing!!
