Test Pyramid is a blueprint divided into three parts that help Devs and QA professionals to get better results. Since the test pyramid increases the efficiency of a Dev team, it plays a vital role in the software testing strategy.
Like everything else, this strategy also comes with a toll. See, the traditional test pyramid consists of three layers: Unit test, Integration test, and End-to-End Test. As a result, it takes a lot of time and effort.
The Dev team requires three to six cycles on average to complete a whole testing phase with this idea. And it takes a lot of manual testing to go through. So, what’s the solution here?
Meet API testing. It’s a testing type that maintains short test cycles and handles frequent changes. In this article, I’ll give you a full-fledged idea about API testing and try to answer all your questions. So, let’s get to it.
API stands for Application Programming Interface. A software testing strategy that checks whether an API performs the way it should define API testing. In other words, it analyzes API’s functionality, readability, performance, and security.
In conventional testing, developers work with standard inputs and outputs. But in API tests, they use software to call APIs, get results and note down the system’s response.
You already know that the conventional test consists of three layers: presentation, business, and database. API works as an add-on to the middle layer (business) of traditional testing. The API test lies between the presentation and business layer in software development.Also read: 9 Best Cybersecurity Companies in the World
Different API tests are available to ensure the ongoing project’s API works as it should. Let’s get to know some of those.
The definition of functional testing is simple. It ensures whether the software of the application is performing within the expected parameters.
This method analyzes the whole codebase and compares it with the intended output to get to a decision. The software can also prevent bugs outside the designed parameters in this process.
Reliability ensure consistency in software testing. It ensures whether an API can perform and function consistently in each testing environment for a specific time. In general, the purpose of this type of API testing is to ensure that the end product is error-free and reliable at the same time.
Validation testing mainly checks the behavior and efficiency of an API. It’s a quality assurance strategy for determining if the product is ready to meet the dev’s and client’s expectations. The testing process is divided into three question sets to verify the entire development process.
In API tests, developers use load testing to understand how an API performs with the increased number of calls. This test helps the development team to agree on whether the product can meet certain real-life expectations under a high load.Also read: Top 10 IoT Mobile App Development Trends to Expect in 2021
Security Testing gives the Dev team an overview of how the API will perform against cyberattacks. The process tests an API’s encryption methods and checks how it behaves with permissions and access controls.
You can call it “Security Test 2.0” because this process is the next level of security testing. In this type, the testers analyze different attacks on API from an outsider’s point of view. This helps them to design better security for the product.
In this API test, developers input massive amounts of invalid data to see how the API responds to errors. It also checks if the API processes those errors or crashes badly.
The general idea of UI testing is to check whether the API or other integral parts’ user interface is running correctly. In terms of the codebase, UI testing is not a significant part of API testing. However, this process helps measure the health and efficiency of the app’s front-end and back-end.
This type of testing is directly associated with the running of the API itself. Mainly, it monitors, overviews, and executes errors and resource leaks of a product.
Traditional testing does not cover all the aspects of back-end testing. As a result, the final product has a high possibility of containing bugs, which is pretty bad. That’s why we need API tests to ensure connections among different platforms are safe and reliable.
However, there’re other benefits of using API tests as well. Let me cover some of those for you.
These are some of the biggest benefits of using API tests. Since you already know it’s a software-dependent testing strategy, you must be expecting a few names to get started with the process.Also read: Top 10 Job Search Websites of 2021
Every developer has two options to run an API test: Write a framework or work with the ready-to-go tools. Yes, both have pros and cons, but I’ll talk about the available software on the market.
There are a lot of API Testing tools out there on the internet. However, as the internet has become a tough place to find the best things, I’ll give you a few names to work with.
API test is more like conventional software testing on steroids. The main difference is steroids have too many cons, but API testing doesn’t. I’ve tried briefly explaining API testing and its benefits in the above article.
Yes, there are a few anti-sides as well. Since the number is way too less, I didn’t feel the urge to address them. One of the biggest problems with API testing is MAINTENANCE.
But I’ve already given you a list of automated tools as a big SOLUTION to this problem. I hope this article was enough to answer all of your concerns.
